Bunionectomy CPT Coding Clinical Coder: Skeletal Anatomy of the Foot A quality improvement organization (QIO) reviewer recently observed that coders “don’t understand the feet” and, as a result, encounter difficulties when they try to code procedures performed on the foot. This coding resource reviews the bones of the foot so that coders can better understand related procedures. Source: Illustration by Ida Dox. From Melloni, June L., et al.

Bunionectomy CPT Coding Clinical Coder: Skeletal Anatomy of the Foot (continued) Bones of the Foot are listed below: Bone(s) Location Description Phalanx; phalanges (pl.) Toes The toes of one foot include a total of 14 bones, or phalanges. Each bone consists of a base, a shaft or body and a head. The first toe (great toe or hallux) has a proximal and distal phalanx. The other toes have three phalanges each: proximal, middle and distal. Metatarsus; metatarsi (pl.) Foot These five long bones are located between the proximal phalanges and the distal row of tarsal bones in the back of the foot. Sesamoid(s) First metatarsal These two small, ovoid bones are found on the head of the first metatarsal bone. They are found embedded within a tendon or joint capsule, principally in the hands and feet. Tarsus; tarsi (pl.) Foot These seven bones of the posterior half of the foot are arranged in two rows. The distal row consists of the medial cuneiform, intermediate cuneiform, lateral cuneiform, cuboid and navicular; the proximal row consists of the talus (located at the ankle) and calcaneus (heel bone). All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 10 Advanced Clinic I. Bunionectomy CPT Coding Clinical Coder: Skeletal Anatomy of the Foot (continued) Terms for procedures frequently performed on the bones of the feet are defined as follows: Term Definition Exostectomy Removal of a benign bone tumor (exostosis)—for example, a bunion or hallux valgus Ostectomy Excision of a bone Osteoclasis Surgical refracture of a bone in the case of a malunion of broken parts Osteoplasty Reconstruction or repair of a bone Osteotomy Surgical division or section of a bone Sequestrectomy Surgical removal of a piece of dead bone Sources: Melloni, June L., et al.

All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 11 Advanced Clinic II. Bunionectomy CPT Coding Bunionectomy: Background Hallux valgus is the lateral deviation or subluxation of the great toe. With progressive subluxation of the first metatarsophalangeal joint, footwear exerts pressure on the medial metatarsal head, and a thickened bursa or “bunion” develops. Many different procedures can be used to correct the bunion deformity. Common to most procedures is the excision of the exostosis (median eminence) from the medial aspect of the first metatarsal head. Osteotomies, bone resection, and joint replacement, which require prolonged convalescence, may be used in severe bunion cases. The CPT codes for bunionectomies are found in the range 28110, 28290 - 28299. In their Complete Global Service Data for Orthopaedic Surgery publication, the American Academy of Orthopaedic Surgeons (AAOS) has identified procedures that are integral to various orthopedic procedures. In most instances, the integral procedures listed do not warrant separate code identification in the CPT coding system. NOTE: Use also the Medicare Hospital Outpatient Correct Coding Initiative (CCI) edits to identify procedures that are “integral to” or “components of” the bunionectomy codes. Hallux valgus is the lateral deviation or subluxation of the great toe. With progressive subluxation of the first metatarsophalangeal joint, footwear exerts pressure on the medial metatarsal head, and a thickened bursa or “bunion” develops. Most cases are asymptomatic, but extreme cases interfere with footwear and become painful. These are the patients who seek medical attention. Many different procedures can be used to correct the bunion deformity. Common to most procedures is the excision of the exostosis (median eminence) from the medial aspect of the first metatarsal head. Osteotomies and bone resection or joint replacement are used in severe cases and require a prolonged convalescence. In addition to the clinical details of these procedures, we also have included “Integral Procedures” often performed as part of the overall procedure and, as such, do not warrant separate code identification in CPT. Integral procedures documented are not intended to present a medical standard of care or practice parameter for the health care community. Please note that procedure codes are listed more than once in some instances to focus on each method/type of repair mentioned in the code description. Coding Tips: • Insertion of a wire with application of skeletal traction is part of the bunionectomy procedure. Do not code the wire insertion separately. • All bunionectomy codes include a sesamoidectomy of the great toe. All CPT Codes © 2003 American Medical Association * Lolita M.

CPT Bunionectomy Codes and Case Studies Type of Bunionectomy: Ostectomy, partial excision, fifth metatarsal head (bunionette) CPT Code: 28110 Procedure Description: Through a lateral longitudinal arthrotomy, the fifth metatarsophalangeal (MP) joint is exposed. The lateral prominence or exostosis of the metatarsal head is resected, and the capsule is tightly imbricated. Integral Procedures: Closure of wound and repair of tissues divided for initial surgical exposure, partial or complete; application of initial; dressing, orthosis, continuous passive motion, splint or cast, including traction; preparation and insertion of synthetic bone substitutes (e.g., hydroxyapatite, coral, methylmethacrylate, demineralized bone matrix); arthrotomy; tenotomy; synovectomy; tenolysis and/or tenosynovectomy; release joint contractures. Diagnostic Implications: There are several types of procedures for bunionette correction. The simple ostectomy described is indicated for prominence of the fifth metatarsal head. A chevron osteotomy may be required for lateral deviation of the fifth metatarsal neck or a diaphyseal osteotomy for a wide 4-5 intermetatarsal angle. Comments (if applicable): Coding Tip - A Tailor’s bunionectomy (the same as a bunionette excision) would be assigned to code 28110. All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 14 Advanced Clinic Bunionectomy CPT Coding Cast Study #1: Operative Report Preoperative Diagnosis: Tailor’s bunion, left foot Postoperative Diagnosis: Tailor’s bunion, left foot Operation(s): Tailor’s bunionectomy and osteotomy, left foot Description of Operation: The patient was brought to the Operating Room, sedated with intravenous sedation, the left foot anesthetized with a total of 12 cc of equal amounts of .5% Marcaine plain plus 2% Carbocaine with 1 cc of Triamcinolone added to the injectable mixture 5 cc of the mixture was used for posterior tibial nerve block. The foot was then prepped with sterile Betadine solution, draped in a sterile fashion and ankle tourniquet applied over appropriate padding. The tourniquet inflated to 250 mm Hg following exsanguination of the foot and ankle with an Esmarch bandage. The Esmarch was removed and the leg placed on the table and the procedure begun. On the dorsolateral aspect of the left fifth metatarsophalangeal joint, a 5 cm curvilinear incision was made. The incision was carried deep by sharp and blunt dissection, cauterizing small bleeders with the Bovie. Subcutaneous tissue was reflected off the dorsal and medial aspect of the fifth metatarsophalangeal joint and a dorsolinear capsulotomy was performed. The capsule was reflected and the periosteum was tagged with simple sutures of #4-0 Vicryl for easier identification later in the procedure upon closing. The periosteum was reflected off the dorsal, lateral and plantar aspects of the metatarsophalangeal joint area and the lateral aspect of the metatarsal head was resected with an oscillating saw. At this point, a failsafe drill hole was placed from dorsal to plantar parallel with the lateral cortex of the bone approximately 1.5 cm proximal to the metatarsal head. An oscillating saw was now used to make an osteotomy cut from the drill hole medially through the medial cortex from dorsal to plantar. This was recut one other time and the osteotomy easily closed with light pressure. Three drill holes were now placed, one distal and two proximal to the osteotomy site, and a double strand of #2-0 monofilament wire was passed through these drill holes from medial to lateral. The wire was then twisted snug with a Kocher clamp and cut, and the cut end placed into one of the proximal drill holes. The osteotomy held in good position and kept the bone well-aligned. There was a slight crack that developed in the lateral cortex through the failsafe hole distally which did not displace the osteotomy at all or make it any less stable. It was, in fact, extremely stable at the time of closure. The wound was flushed with copious amounts of sterile saline. The periosteum and capsule were closed with simple interrupted sutures of #4-0 Vicryl. The subcutaneous tissue closed with #4-0 Vicryl and the skin with a continuous subcutaneous stitch of #5-0 Vicryl. Mastisol’s solution and _ inch Steri-Strips were further used to coapt the would edges. The wound was then dressed with sterile 4x4’s, Kling and a Coban dressing applied. The tourniquet was released, normal blood flow returned to the toes as evidence by pink coloration and blanching of the toes on pressure. Estimated blood loss was less than 1 cc. There were no complications. The patient tolerated surgery well and left the Operating Room to go to Recovery in apparent satisfactory condition. Specimens were disposed of.

Hemostasis: Pneumatic ankle tourniquet 250 mmHg. Tourniquet Time: 95 minutes Materials: 3-0 Vicryl, 4-0 Vicryl, 4-0 nylon. Pathology: None Procedure/Findings: The patient was placed on the operating room table in the supine position. A well-padded ankle tourniquet applied to her right ankle. After aforementioned anesthesia, the tourniquet was inflated to 250 mmHg. The foot was exsanguinated and incisions were planned 4 cm in length over the fifth metatarsal head and neck area. This was made with a #15 scalpel blade. Blunt and sharp tissue dissection took place, denuding the fifth metatarsal of periosteal capsule. The fifth metatarsal having noted to be significantly prominent laterally. Next, utilizing a sagittal saw, the prominence was removed and the dorsal exostosis was rasped and smoothed. There was large amounts of normal sterile saline and periosteum closed with a 3-0 Vicryl sutures in superficial fascia, 3-0 Vicryl suture for the skin, 4-0 Vicryl suture running subcuticular stitch. Next the fifth digit was examined. Two semi-elliptical incisions were made obliquely across the fifth digit and upon sharp dissection took place to the TIPJ and DIPJ. Next, utilizing the sagittal saw, the head of the proximal phalanx was removed. The remaining base was remodeled with a rongeur and flushed with large amounts of normal sterile saline. The digit was then de-rotated and the tendon All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 17 Advanced Clinic Bunionectomy CPT Coding Case Study #2 cont’d repaired with a 3-0 Vicryl suture, the skin with 4-0 nylon suture holding the digit in the corrected position. The fourth digit was then examined and noted to be in significant abducted varus position. Two synovial elliptical incisions were made over the PIPJ. The central ellipse of skin was removed. Blunt and sharp digital dissection took place down to the extensive digitorum lateris tendon. This was incised with a #15 scalpel blade. The head of the middle phalanx was then removed with a sagittal saw and remodeled utilizing a rongeur. This was flushed with large amounts of normal sterile saline and repaired with 3-0 Vicryl suture, derotating the toe and repaired with 4-0 nylon suture. The areas were then injected with 3 cc of 0.5% Marcaine plain. The foot was then dressed with Betadine soaked in Adaptic, 4 x 4’s, Kerlix and cling. The patient was transferred to the operating room to the recovery room with vital signs stable and neurovascular status to a right foot fully intact. She is to be partial weightbearing and surgical shoe. She was given medications for pain. Percocet one tablet 9.6h.p.r.n. pain, Motrin 800 mg one tablet t.i.d. She is to return for a postoperative visit in 48 hours. CPT Procedure/Modifier Code(s):__________________________________________ All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 18 Advanced Clinic Bunionectomy CPT Coding Type of Bunionectomy: Simple exostectomy/Silver-type procedure CPT Code: 28290 Procedure Description: A medial longitudinal arthrotomy exposes the first MP joint. The median eminence or exostosis is osteotomized, and the medial capsule is repaired. Integral Procedures: Closure of wound and repair of tissues divided for initial surgical exposure, partial or complete; application of initial; dressing, orthosis, continuous passive motion, splint or cast, including traction; preparation and insertion of synthetic bone substitutes (e.g., hydroxyapatite, coral, methylmethacrylate, demineralized bone matrix); arthrotomy; synovial biopsy; extensor tenotomy; synovectomy; capsular release and reconstruction; removal of additional exostoses in the area of the joint; internal fixation; articular shaving; arthroscopy; removal of bursal tissue; excision of redundant skin and closure; capsular arthroplasty; excision of bone or synovial cysts. Diagnostic Implications: This procedure is performed for a mild bunion deformity in which the metatarsal head is slightly prominent on the medial side. Comments (if applicable): A simple exostectomy involves no extensive corrective procedures but may necessitate a release of contracted lateral structures. All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 19 Advanced Clinic Bunionectomy CPT Coding Case Study #3 Operative Report Preoperative Diagnosis: Hallux Valgus Deformity with Degenerative Joint Changes, Right Toe Postoperative Diagnosis: Hallux Valgus Deformity with Degenerative Joint Changes, Right Toe Procedure: Silver Bunionectomy, First Metatarsophalangeal Joint, Right Toe Anesthesia: Monitored Anesthesia Care with Local Infiltration of 0.5% Marcaine Plain and 1% Lidocaine Plain in a 1:1 Mixture Totaling 12 cc. Hemostasis: Ankle tourniquet inflated at 250 mmHg. Procedure: The patient was taken to the operating room and placed in the supine position on the surgical table at which time an IV was started in the patient’s arm for purpose of intravenous sedation and hydration. Also 1 gm of Ancef was given to the patient in an intravenous push type form. The patient’s right lower extremity was then prepped and draped in the usual sterile manner. Next attention was then directed to the lower right extremity which was elevated about a 45 degree angle and was exsanguinated and a pneumatic tourniquet was inflated to 250 mmHg for the purpose of creating hemostasis. Attention was then directed to the right metatarsophalangeal joint where a 4.5 dorsal linear incision was made medial to the extensor hallucis longus tendon and parallel to center over the right first metatarsophalangeal joint. The incision was deepened in the same plane with special attention paid to all bleeders which were Bovie ligated and retracted out of the surgical field as necessary. Special attention was paid to the neurovascular field as necessary. Special attention was paid to the neurovascular bundle which was retracted both medially and laterally from the surgical field. An incision was made through the subcutaneous down to the capsule and the periosteal structure layer. With a fresh #15 blade an incision was made through the capsule of the periosteal tissue in the same plane and was reflected medially and laterally and dorsally to get exposure to the first metatarsal bone. Next the integrity of the first metatarsophalangeal joint was then evaluated. The articular cartilage of the head of the first metatarsal was observed to be nonerosive with severe areas of proliferation surrounding the dorsal medial and dorsal lateral aspects of the first metatarsal head. With the use of the oscillating saw, the medial eminence was resected from the site of the first metatarsal head in toto and passed off the surgical field for pathological study. The first metatarsal head was then assessed. With the use of a small oscillating bur all bony proliferation on the dorsal medial and dorsal lateral aspects of the first metatarsal head were burred smooth to contour the bone, as well as the medial aspect of the metatarsal head was burred smooth. The surgical site was then irrigated with copious amounts of saline solution. The forefoot was then loaded and the hallux was taken through a range of motion exhibiting good dorsiflexion. The surgical site was then flushed again with copious amounts of saline solution. The periosteal capsule was then closed utilizing 3-0 Vicryl in a running continuous fashion. The subcutaneous tissue was then closed using 3-0 Vicryl in a horizontal mattress suture type fashion. The skin was closed using 4-0 nylon in a continuous running interlocking fashion. All surgical sites had been dressed with Betadine-soaked Adaptic, sterile 4x4 gauze pads, and sterile Kling in a compressive type fashion. The tourniquet was released and normal vascular status returned to all of the digits of the right foot. At no time during All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 20 Advanced Clinic Bunionectomy CPT Coding Cast Study #3 cont’d the surgical procedure was the sterile technique broken, and sterile conditions remained at all times. After a brief period in the recovery room the patient was to be discharged with postoperative pain medications of Vicodin one tablet to be taken p.o. q.6h. p.r.n. The patient was dispensed one postoperative shoe and cane to be used at all times. The patient was also discharged with written postoperative instructions. The patient is instructed if an emergency were to arise to contact Dr. Rucker at 202-801-5474 or call the page operator at Howard University Hospital. CPT Procedure/Modifier Code(s):__________________________________________ All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 21 Advanced Clinic Bunionectomy CPT Coding Type of Bunionectomy: Keller CPT Code: 28292 Procedure Description: A longitudinal medial arthrotomy with resection of the median eminence and one-third of the base of the proximal phalanx is performed.

Bunion of the right foot. 2. Hallux valgus. Postoperative Diagnoses: 1. Bunion of the right foot. 2. Hallux valgus. Procedure Performed: Implant arthroplasty with correction of bunion to the right foot. Anesthesia: Local with IV sedation. Hemostasis: Pneumatic ankle tourniquet at 250 mmHg for 69 minutes. Procedure: The 72-year-old patient was brought from the holding area and placed on the operating table in the supine position. After the administration of IV sedation, a local block was achieved using a 0.5% MARCAINE plain, approximately 17 cc used in a Mayo block fashion about the right first metatarsal. The foot was prepped and draped and then an Esmarch bandage was applied for exsanguination, and a pneumatic tourniquets was inflated 250 mmHg. Bunionectomy via implant arthroplasty of the right first metatarsal phalangeal joint. Attention was directed to the dorsal medial aspect of the right foot in the area of the first metatarsal phalangeal joint. Just medial to the extensor tendon a 5 cm curvilinear incision was made. The incision was deepened via sharp and blunt dissection, taking care to preserve and protect all neurovacular structures. Those structures encountered were retracted to the side or bovied as required. The incision was carried down to the level of the joint capsule, about the first metatarsal phalangeal joint. Here a T-shaped capsulotomy was performed extending from the base of the distal phalanx onto the neck of the first metatarsal and also down along the medial aspect of the joint. All soft tissue was then dissected free from the head of the first metatarsal and the base of the proximal phalanx. There was quite a bit of erosions noted to the joint cartilage, a lot of gouty tophi present imbedded into the joint cartilage and pocketed into the joint capsule, The capsule was quite thick around the head of the first metatarsal. As much as possible this was cleaned up and removed. I then used a power oscillating saw to resect the cartilaginous head of the first metatarsal and the cartilaginous surface of the base of the proximal phalanx. I used a Shannon-type burr to ream out both the first metatarsal distal portion and proximal portion of the proximal phalanx of the great toe. In doing this I was able to create a channel for acceptance of the implant stems. I went ahead and irrigated the wound and used sizers to measure the appropriate implant. I decided on a total flexible hinged implant, size #3, and we used the grommets. I went ahead and placed All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 27 Advanced Clinic Bunionectomy CPT Coding Case Study #4 cont’d this in the normal manner and reevaluated the joint. We found that the implant was the right size for the patient. There was good range of motion at the first metatarsal phalangeal joint with no impingement of bone. We did a final irrigation of the wound and then began to close the soft tissues using 3-0 and 2-0 Vicryl for the periosteal tissues and joint capsule. I performed a capsulorrhaphy along the medial aspect of the head of the first metatarsal and then closed subcutaneous tissues and skin using 4-0 Vicryl in a running subdermal suture fashion. I augmented the closure with Steri-Strips, and then injected 1 cc of dexamethasone phosphate for his postoperative anti-inflammatory effect. We dressed the wound with Adaptic, sterile 4x4 gauze, 3inch Kling, and a mildly compressive Coban wrap. Pneumatic tourniquet was released to reveal an instantaneous reflex hyperemia to digits 1-5 of the right foot. Estimated blood loss for this procedure was less than 5 cc. There were no specimens for pathology. The patient tolerated the surgery and anesthesia without complication and left the operating room for recovery with vital signs stable and neurovascular status intact.

Postoperative Diagnoses: 1. Painful bunion in the left foot. 2. Hallux valgus. Procedure: Left foot Austin bunionectomy with hemi-implant to the great toe and 3.5 mm screw fixation Anesthesia: Pneumatic ankle tourniquet at 250 mmHg. Procedure in Detail: The 71-year-old female patient was brought from the holding area and placed in the operating table in the supine position. After administration of IV sedation, a local block was achieved using 0.5% MARCAINE plain. The left foot was then prepped and draped in the usual sterile manner. The foot was elevated and an Esmarch bandage was applied and then a pneumatic tourniquet was inflated to 250 mmHg. The left foot Austin bunionectomy with 3.5 mm screw fixation and hemi-implant to the great toe. Attention was directed to the dorsomedial aspect of the left foot where a 6 cm curvilinear incision was made just medial to the extensor tendon of the great toe. The incision was deepened via a sharp and blunt dissection taking care to preserve and protect the neurovascular structures. The structures encountered were retracted to the side or bovied as required. The incision was carried to the level of the deep fascia and joint capsule around the first metatarsophalangeal joint. Here a T-type capsulotomy was performed exposing the base of the proximal phalanx and head and neck region of the first metatarsal. All the soft tissue was dissected away from these areas. There was quite a bit of hypertrophic bone medially which was resected using a power oscillating saw off the head of the first metatarsal. I then distracted the hallux to reveal the first metatarsophalangeal joint. While I found most of the cartilage intact and nondeviated, there was quite a bit of destruction to the cartilage itself because of chronic gouty arthritis. Almost 50% of the cartilage was covered over by a gouty tophus which could not be scrapped clean. It was at this point that I went ahead and decided do the hemi-implant of the great toe joint placing a titanium implant in place. I went to the first intermetatarsal space and did a complete lateral release of the first metatarsophalangeal joint consisting of release of the fibular sesamoidal apparatus for release of the conjoined adductor tendon and then I bordered up the forefoot and found the hallux to be free of all lateral contracture. I then addressed the medial head of the first metatarsal and the anatomical and the surgical neck area and made a through-and-through Vshaped osteotomy. I then distracted the head of the metatarsal and translocated it laterally about 0.5 cm, and then re-impacted it on to the shaft of the first metatarsal. Temporary fixation All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 29 Advanced Clinic Bunionectomy CPT Coding was achieved using 45 K wire. Permanent fixation was achieved using a Duvall 3.5 mm cannulated Case Study #5 cont’d screw 20 mm in length abutted from dorsal proximal to plantar distal across the osteotomy site. Once this was in place, the osteotomy was stable and in good anatomical position. I removed the temporary fixation and then removed the medial shelf of bone created by the translocation of the first metatarsal head. All rough osseous edges were smoothed using a Cottle rasp. I went ahead and irrigated the wound at this time and then addressed the base of the proximal phalanx. Once the sufficient portion of the base of the proximal phalanx was exposed, I made a through-and-through osteotomy removing the proximal 3 to 4, maybe 5 mm base of the proximal phalanx, effectively removing the cartilaginous surface. I then went ahead and prepped for a hemi-implant. By the size of bone, it was felt that a median hemi-implant would be the appropriate size. I prepped the bone creating a small hole in the edge of the medullary canal and then using the instrumentation provided created a channel into the canal that the implant could then seat in. We then opened up a medium Biopro hemi-implant and seated into place where it sat flush against the base of the proximal phalanx. I then irrigated the wound again. I took the hallux range of motion and found it to be in good alignment and free of any grinding, crepitus, nor did it catch on any aspect of the head of first metatarsal cartilage. I went ahead and irrigated the wound one more time and inspected for any remaining debris, of which none was found. I closed the joint capsule and periosteal tissue using 2-0 Vicryl and 3-0 Vicryl. I then closed the subcutaneous tissues and skin with 4-0 Vicryl in a running subcuticular suture fashion. I augmented this with Steri-Strips. I injected 1 cc of dexamethasone phosphate for its postoperative anti-inflammatory effects. Dressed the wound with Adaptic, sterile 4x4 gauze, 3 inch Kling, and a mildly compressive Coban wrap. The pneumatic tourniquet was released after 58 minutes to reveal good hyperemia to digits 1 through 5 of the left foot. Estimated blood loss for this procedure was less than 10 cc. There was no specimen for pathology. The patient tolerated the surgery and the anesthesia without complications. She left the operating room to recovery with vital signs stable and neurovascular status intact.

Once adequate anesthesia was obtained, tourniquet was placed and the left lower extremity was prepped and draped in routine sterile fashion. Leg was exsanguinated, tourniquet was inflated. A 3-4 cm longitudinal incision was made over the medial aspect of the left great toe directly over the bunion. We sharply incised down to the capsular layer. Then, with a distally based flap, we All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 33 Advanced Clinic Bunionectomy CPT Coding Case Study #6 cont’d elevated the capsule exposing underlying MP joint and bunion. Once we had adequate exposure, we were able to take off the bunion with the sagittal saw. Next, attention was turned on the Mitchell osteotomy. Once adequate exposure was obtained, we placed two drill holes. The first one was about 1cm proximal to the articular surface. The second one, about 1 _ -2cm proximal and slightly more medial. Next, sagittal saw was used to make a transverse cut half way across, just proximal to the first drill hole. Another parallel cut was made just behind this one and cut all the way across. The osteotome was used to take out the wafer of bone which produced a nice ledge/step cut of the Mitchell osteotomy. Next, the articular surface piece was immobilized medially and the step cut was wedged into place. At this time, a #1 Vicryl stitch was used to pass through the drill holes and tie over the top for fixation. At this time, the toe was deviated slightly laterally and the distal based capsular flap was tensioned. This straightened the toe nicely. Next, before repairing the capsule, we again took the sagittal saw and shaved off the medial prominence after Mitchell osteotomy. Then, the capsule was tensioned, was repaired with interrupted #1 Vicryl keeping the toe in a corrected position. Next, attention was turned to the hammertoe of the second small toe. Elliptical incision was made over the dorsal aspect of the PIP joint. This again was circumcised. Next, a capsular incision was made exposing the underlying articular surface. Articular surface were removed with rongeur’s, both sides. Then a K-wire was inserted distally, to come out just below the toenail.

Attention was directed to the dorsal aspect of the patient’s right medial first metarsophalangeal joint where a 5.0 cm incision was made utilizing a number 15 blade. The incision was made deepened in the same surgical plane, being careful to retract the neurovascular structures both medially and laterally. All bleeders were cauterized as encountered utilizing a Bovie. A dorsal capsulotomy was performed utilizing a number 15 blade. All capsular and periosteal tissues were removed from the head and mid shaft of the first metatarsal. This allowed for exposure of a large proximal phalanx base, which appeared to be hypertrophied and arthritic in nature. All arthritic bone was resected from the surgical site and removed in toto. There was also a large medial eminence and this was resected utilizing a sagittal saw and removed in toto from the surgical site. All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 41 Advanced Clinic Bunionectomy CPT Coding Case Study # 9 cont’d Attention was then directed to the first metatarsal where a V-shaped osteotomy was made through-and-through with the apex of the osteotomy distal within the mid shaft of the first metatarsal head. This capital fragment was then translated laterally into a more rectus position. The first metatarsal space was explored and found to have a tight adductor tendon. This adductor tendon, along with the sesamoidal apparatus, was also released utilizing a number 15 blade. The capital fragment was then fixated temporarily utilizing a 1.1. mm guidewire and 3.0 mm cannulated screw was placed into the site, going from the dorsal proximal to the plantar distal, to hold the fragment permanently in place. The remaining bone meal was resected utilizing and sagittal saw and all bony prominences were smoothed utilizing a hand rasp. The 1.1 mm guidewire was removed utilizing a K-wire driver. The bone cyst in the first metatarsal head was curetted and repacked with bone from the medial eminence. The wound was then copiously irrigated with warm normal sterile saline. Capsular tissues were approximated utilizing 2-0 Vicryl in a simple interrupted fashion. The subcutaneous tissue was approximated utilizing 3-0 Vicryl in a simple interrupted fashion. The skin was approximated utilizing 4-0 Monocryl in a running subcuticular fashion. The wound was then dressed with gauze, KLING and an ACE bandage. The pneumatic ankle tourniquet was lowered after a total tourniquet time of 50 minutes. Disposition: The patient was escorted to the recovery room where vital signs were stable and vascular status was at preoperative levels. Postoperative Instructions: The patient will follow up with me as an outpatient. Hemostatis: Pneumatic ankle tourniquet at 250mmHg for a total tourniquet time of 50 minutes. CPT Procedure/Modifier Code(s):__________________________________________ All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 42 Advanced Clinic Bunionectomy CPT Coding Type of Bunionectomy: Lapidus-type procedure CPT Code: 28297 Procedure Description: This procedure involves correcting the angulation of the first metatarsal by fusing the first metatarsocuneiform joint and the tibial side of the base of the second metatarsal. This is not a variation of the chevron procedure because there is no metatarsal osteotomy performed at the proximal aspect of the first metatarsal shaft. Integral Procedures: Closure of wound and repair of tissues divided for initial surgical exposure, partial or complete; application of initial; dressing, orthosis, continuous passive motion, splint or cast, including traction; preparation and insertion of synthetic bone substitutes (e.g., hydroxyapatite, coral, methylmethacrylate, demineralized bone matrix); arthrotomy; tendon release or transfer; synovectomy; capsular release and/or reconstruction; removal of additional exostoses in the area of the joint; internal fixation; removal of bursal tissue; repair of released tendon; arthrodesis, tarsometatarsal joint; local bone graft; proximal first metatarsal osteotomy. Diagnostic Implications: This procedure is performed for metatarsus primus varus, a condition in which the metatarsal is angled toward the midline of the body, and the digit or phalanx is angled away from the midline of the body. Comments (if applicable): The complications include shortening of the first ray (the length of the metatarsal to the distal phalanx) and possible transfer of loading force to the lesser metatarsals with resulting metatarsalgia.

Jones Consulting Services 43 Advanced Clinic Bunionectomy CPT Coding Case Study #10 Operative Report Date of Procedure: April 26, 2002 Procedure Performed: Lapidus bunionectomy with screw fixation. Anesthesia: MCA Preoperative Diagnosis: Severe hallux valgus with hypermobile first metatarsal cuneiform joint, right foot. Postoperative Diagnosis: Severe hallux valgus with hypermobile first metatarsal cuneiform joint, right foot. Description of Procedure: The 21 year-old patient was prepped and draped in the usual sterile fashion. Anesthesia was achieved with the instillation of approximately 18cc of 1% plain Xylocaine. The foot was then exsanguinated using an Esmarch bandage. The tourniquet was inflated at the ankle level to 250 mmHg. A long linear incision was made with a number 15 blade across the first metatarsal cuneiform joint area and extending down to the base of the proximal phalanx of the hallux. All bleeders were identified and ligated. A linear capsulotomy was made in the first metatarsophalangeal joint and the medial eminence of the first metatarsal head was exposed. It was removed with a power saw and then rasped smooth. Attention was then directed to the first metatarsal interspace where the adductor tendon was released from its attachments and the attachments to the fibular sesamoid were freed, as well as the intermetatarsal ligaments. Attention was then directed to the base of the first metatarsal where a linear capsulotomy was again performed. The first metatarsal cuneiform joint was exposed with sharp and blunt dissection. The first osteotomy performed was when a parallel portion was removed from the All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 44 Advanced Clinic Bunionectomy CPT Coding Case Study 10 cont’d cuneiform, from dorsal to plantar. Then the first metatarsal was held in the corrected position and a small angular piece was removed with the power saw. The area was inspected for any remaining pieces of bone, with a laminar spreader holding the joint open. All areas were then copiously flushed. Utilizing a 0.045 K-wire, the bone on the base of the first metatarsal was fenestrated to a small to moderate degree. It was then held in correct apposition and two threaded K-wires were inserted in a crossing fashion for stabilization. An x-ray was then taken in order to confirm the position of the first metatarsal cuneiform joint. It was found to be in good position, as were the cannulated K-wires. Utilizing one 22 mm x 4.0 cannulated screw and one 36 mm x 4.0 cannulated screw, the joint was then fixated. Alignment was then checked again and all areas were copiously flushed. The capsule was then closed with 3-0 PDS interrupted sutures. The subcutaneous tissues were closed with 4-0 Vicryl simple interrupted sutures. The flexor hallucis brevis was identified and a small portion was removed. The skin was closed with a combination of 5-0 Monocryl running subcuticular suture and steri-Strips. Then approximately 10cc of 0.25% Marcaine were instilled for postoperative analgesia. A dry sterile dressing was applied. Upon release of the tourniquet, patency of all toes was noted. A posterior splint was then applied in the operating room. Disposition: The patient transferred to the recovery room in good condition.

Jones Consulting Services 45 Advanced Clinic Bunionectomy CPT Coding Case Study #11 Operative Report Preoperative Diagnosis: Arthritis, left foot. Postoperative Diagnosis: Arthritis, left foot. Operation: 1. Lapidus bunionectomy 2. Arthrodesis, second and third tarsometatarsal joints. 3. Osteotomy of the fourth metatarsal. Anesthesia: Monitored. Indications: This 77-year-old white female has had chronic pain in the left foot associated with instability and degenerative joint disease in the tarsometatarsal joints, severe bunion deformity, and pain under the metatarsal heads. Procedure/Findings: Under IV sedation, a left ankle block was instilled with 1% Xylocaine, 0.25% Marcaine. The left foot and ankle were prepped and draped in the usual fashion with tourniquet applied to the left ankle. The tourniquet was inflated to 250 mmHg. A longitudinal 4 cm incision was made on the dorsal foot between the first and second metatarsal heads. Soft tissue was bluntly dissected to lateral capsule of the first metatarsophalangeal joint, which was incised longitudinally. The lateral sesamoid was mobilized. He capsule was further perforated to allow realignment of the great toe parallel to the first metatarsal. The medial aspect of the first metatarsophalangeal joint was exposed through a longitudinal 5 cm incision. Soft tissue was bluntly dissected to the joint capsule, which was incised in a distally based V and sharply elevated. A portion of the medial eminence was resected with a rongeur, and the medial sesamoid and remainder of the plantar plate was mobilized with sharp and blunt dissection. The first tarsometatarsal joint was exposed through a dorsal 6 cm incision. Soft tissue was bluntly dissected down to the joint. The joint capsule was incised. The articular surfaces of the tarsometatarsal joint were resected with osteotomes and rongeurs and high speed bur, and a portion of the medial first metatarsal was resected to allow realignment of the first metatarsal parallel to the second. This was stabilized initially with a K wire, subsequently with a staple, and the K wire removed. The second tarsometatarsal joint was exposed through a dorsal 5 cm incision. Soft tissue was bluntly dissected down to the joint capsule which was incised. The dorsal osteophytes were resected with osteotome and rongeurs. The articular surfaces of the joint were resected with osteotome, rongeur, and high speed bur. The joint aligned appropriately. It was stabilized with a single dorsal implanted staple. The third tarsometatarsal joint was treated in similar fashion. All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 46 Advanced Clinic Bunionectomy CPT Coding Case Study #11 cont’d Following that the fourth metatarsal was osteotomized through a dorsal 4-cm incision. The periosteum was incised and elevated, and a horizontal osteotomy was fashioned to the fourth metatarsal. This was stabilized with a 2.0 cortical screw. The osteotomies were carefully assessed using a C-arm, and the alignment was deemed satisfactory. Fixation was satisfactory. The fifth metatarsal was subsequently judged to be in satisfactory alignment and was therefore not osteotomized. At this point the medial capsule of the first metatarsophalangeal joint was reefed with interrupted 2-0 Vicryl sutures. The tourniquet was then released. Bleeding was controlled with electrocautery, and all wounds were closed with interrupted 4-0 nylon sutures. Sterile dressings were applied. The patient tolerated this procedure well and was taken to the recovery room in satisfactory condition.

All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 48 Advanced Clinic Bunionectomy CPT Coding Type of Bunionectomy: By Double Osteotomy CPT Code: 28299 Procedure Description: Code 28299 represents a combination of codes 28296 and 28310-28315. As bunion surgery has evolved, it is now common practice to perform a double osteotomy. For the correction of hallux valgus deformities with double osteotomy, two operative procedures must be performed. The first is an osteotomy (i.e., chevron) of the distal first metatarsal with correction of the hallux valgus, followed by an osteotomy of the proximal phalanx to correct additional angular deformity. This code may also be used to report two osteotomies of the first metatarsal. Example: A Chevron osteotomy is performed at the base of the first metatarsal, and an Akin osteotomy is performed on the proximal phalanx. (Also see code 28296 for chevron, and 28298 for Akin osteotomy.) Integral Procedures: Closure of wound and repair of tissues divided for initial surgical exposure, partial or complete; application of initial; dressing, orthosis, continuous passive motion, splint or cast, including traction; preparation and insertion of synthetic bone substitutes (e.g., hydroxyapatite, coral, methylmethacrylate, demineralized bone matrix); any combination of hallux valgus procedures; includes all osteotomies of the first metatarsal and the first proximal phalanx. Diagnostic Implications: This procedure is usually performed for a more pronounced hallux valgus that cannot be corrected by a chevron osteotomy alone.

Jones Consulting Services 49 Advanced Clinic Bunionectomy CPT Coding Case Study #12 Operative Report Preoperative Diagnoses: Hallux abducto valgus deformity of the right foot and metatarsus primus varus deformity of the right foot. Postoperative Diagnosis: Hallux abducto valgus deformity of the fight foot and metatarsus primus varus deformity of the right foot with the inclusion of arthritis of the first metatarsophalangeal joint area of the right foot. Operation: Austin bunionectomy and metatarsal osteotomy and Akin osteotomy of the right hallux. Anesthesia: Intravenous sedation. Hemostasis: The patient had an ankle tourniquet for hemostasis. Procedure/Findings: On October 19, 2001, the patient was taken from the preoperative holding area to the operating room and placed on the operating room table in the supine position. Following the induction of intravenous sedation and regional local anesthesia, the right foot was prepped and draped in the usual sterile manner. The right foot was then elevated 60 deprees from the horizontal plane for the purpose of preoperative exsanguination of the limb. During that threeminute time period of elevation, the pneumatic ankle tourniquet was applied to a well-padded site just proximal to both malleoli. The pneumatic ankle tourniquet was then elevated to a level of 250 mmHg for the purpose of intraoperative hemostasis. The right lower extremity was then returned to the operating room table. The remainder of sterile draping was completed, and the following procedure was performed: Austin Bunionectomy and Metatarsal Osteotomy: Attention was directed to the first metatarsophalangeal joint area. At this time, there was noted to be a prominent bunion deformity and medially deviated first metatarsal. Therefore, at this time, an approximately 3 cm dorsolinear incision was created over the dorsal aspect of the first metatarsophalangeal joint of the right foot. The incision was carried down to the level of the subcutaneous tissues, and all coursing venous tributaries were identified, clamped, cut, electrocoagulated, and ligated as necessary. All vital neuromuscular structures were identified, underscored, mobilized, and retracted in a medial and lateral direction. Next, utilizing a combination of sharp and blunt dissection, the incision was carried down into the first intermetatarsal space. A lateral release was performed. Attention was then redirected back up to the dorsomedial aspect of the first metatarsal. At this time, a linear capsulotomy was performed within the margins of the original skin incision. The capsular and periosteal tissues were then dissected free in one confluent layer both medially and laterally. This delivered into view the first metatarsophalangeal joint. It should be noted that there was a lot of inflamed tissue around the first metatarsophalangeal joint area. There was also some exostoses of bony prominences around the first metatarsal and a very prominent bump on the medial aspect of the first metatarsal. At this time, utilizing a sagittal saw, an osteotomy was created within the medial aspect of the first metatarsal. The osteotomy was oriented from dorsal to plantar, distal to All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 50 Advanced Clinic Bunionectomy CPT Coding Case Study #12 cont’d proximal, through and through in such a fashion to remove that prominent bump of bone. The exostoses and bony prominences around the dorsal aspect of the first metatarsal were also osteotomized and removed from the surgical site. Attention was then directed to the medial aspect of the first metatarsal. At this time, a V-shaped Austin bunionectomy was performed from medial to lateral, through and through. The osteotomy was created in such a fashion to allow for transposition of the first metatarsal head in a lateral direction. The first metatarsal head was then transposed approximately one third the width of the metatarsal in a lateral direction and then impacted onto the shaft. At this time, it was fixed in place utilizing an OrthoSorb taper pin driven from dorsal distal lateral to proximal plantar medial. It was also fixed in place utilizing a 0.045 K-wire driven from dorsal proximal medial to plantar distal lateral. The pins crossed the osteotomy site. The osteotomy was well fixated. Attention was then directed to the medial aspect of the first metatarsal. At this time, the redundant cortical portion of bone, which was created by the transposition of the first metatarsal head, was now osteotomized from dorsal to plantar, distal to proximal, through and through. That osteotomized portion of bone was then rasped to a more smooth and even contour. The wound was then flushed with copious amounts of sterile saline solution. Attention was then directed to the hallux. At this time, the following procedure was performed: Akin Osteotomy of the Right Hallux: Attention was directed to the right hallux which was noted to sit in a laterally deviated position. Therefore, at this time, the previous skin incision was extended by 1.5 cm over the hallux area. The incision was carried down to the level of the subcutaneous tissues. All coursing venous tributaries were identified, clamped, cut, electrocoagulated, and ligated as necessary. All vital neurovascular structures were identified and retracted from the incision site. Next, utilizing deeper dissection, the base of the proximal phalanx was exposed. At this time a “V” or wedge-shaped osteotomy was performed in the proximal aspect of the proximal phalanx. The osteotomy was performed in such a fashion to allow for a wedge of bone to be removed with the apex lateral and the base medial. The wedge or bone was removed from the surgical site. The osteotomy was feathered. It was closed and then fixed in place utilizing a 0.045 K-wire driven from dorsal distal lateral to proximal plantar medial. The K-wire crossed the osteotomy site. It engaged the cortices. The osteotomy was well fixated. The wound was then flushed with copious amounts of sterile saline solution. Attention was directed towards closure. The capsular tissues were recoapted and maintained utilizing #4-0 Vicryl. The subcutaneous tissues were recoapted and maintained utilizing #4-0. The skin was then recoapted and maintained utilizing #5-0 Prolene. The incision was then further reinforced utilizing _ inch Steri-Strips. An injection of Solu-Medrol was instilled around the surgical site. A dressing consistent of Adaptic, 3 x 3’s, 3 x 3 splints, a Kling, a Kerlix, and an Ace wrap was applied in a sterile, compressive and corrective fashion. The patient, having tolerated the surgery and anesthesia well, with vital signs stable and afebrile, was then transported to the post-anesthesia recovery room for further monitoring.

Hallux limitus of the left great toe joint. 2. Arthralgia 3. Plantar fasciitis of the left heel. Postoperative Diagnoses: 1. Hallux limitus of the left great toe joint. 2. Arthralgia. 3. Plantar fasciitis of the left heel. Title of Procedure: 1. Youngswick decompressional bunionectomy, left foot, with internal fixation. 2. Endoscopic plantar fasciotomy (EPF) procedure of the left heel. Anesthesia: Local with IV sedation. Hemostasis: Pneumatic ankle tourniquet at 250 mmHg for 61 minutes. Procedure in Detail: The 45-year-old female patient was brought from the holding area and placed on the operating table in the supine position. After administration of IV sedation, a local block was achieved using 0.5% Marcaine with epinephrine about the heel, approximately 10 cc, and about 20 cc of 0.5% Marcaine plain in a Mayo block fashion about the left first metatarsal. The foot was then prepped and draped in the usual sterile manner. The foot was elevated from the table and Esmarch bandage applied. The pneumatic tourniquet was inflated to 250 mmHg. Procedure No. 1: EPF procedure, left heel. It was decided that excessive manipulation and force would be needed to stress across the foot while doing this procedure and it was felt we should do this procedure first before any osteotomies in the first metatarsal. We, therefore, identified the plantar medial aspect of the left heel at the origin of the plantar fascia and here made a 1 cm linear incision. I used curved hemostats to bluntly open the area up to identify the most medial extent of the plantar fascia. I then used a fascial elevator and passed it from medial-to-lateral inferior to the plantar fascia. I then introduced the trocar cannula along the same plane and where it dimpled the skin on the lateral aspect of the heel I made a second 1 cm linear incision and then passed the trocar cannula through that incision. The trocar was removed leaving the cannula in place. I introduced the camera through the medial portal and hook blade through the lateral portal. I was able to hook the most medial extent of the plantar fascia and then sever it from a medialto-lateral direction severing effectively the medial and intermediate bands of fascia. The plantar musculature superior to the fascia became visible once there was good separation of the fascia. I irrigated the area and then reinspected it and found it to be free of all fibrous attachments where I had released it. I loaded up the foot and palpated the medial arch and found it to be also free of any tension from the plantar fascia. I removed the cannula system and then closed the wound edges with 4-0 nylon in horizontal mattress suture fashion, one on each side of the heel. All CPT Codes © 2003 American Medical Association * Lolita M. Jones Consulting Services 54 Advanced Clinic Bunionectomy CPT Coding Case Study #13 cont’d Procedure No. 2: Youngswick decompressional bunionectomy of the left foot with Duval screw fixation 3.5 mm in diameter. Attention was directed to the dorsal medial aspect of the foot at the area of the first metatarsophalangeal joint where there was easily palpated bony spurs present on the head of the first metatarsal dorsally. Also noted was limited range of motion in the area of dorsiflexion. Here, in this area, I made a 6 cm curvilinear incision. The incision was deepened via sharp and blunt dissection taking care to preserve and protect all neurovascular structures. Those structures encountered were retracted to the side or bovied as required. The incision was carried down to the level of the deep fascia and joint capsule around the first metatarsophalangeal joint. Here an inverse L-capsulotomy was performed and all soft tissues were dissected free from the dorsal head and medial aspects of the head of the first metatarsal. This in fact did reveal quite a bit of hypertrophic bone formation on the dorsal aspect of the head of the first metatarsal. Using an oscillating saw, I was able to resect this bone and remove it from the wound in total. I then inspected the joint. I found that there was cartilage satisfactorily covering the base of the proximal phalanx, but the dorsal third of the head of the first metatarsal showed erosion of the cartilage and rough bone. I went ahead and smoothed any rough osseous edges and then I took a 45 K-wire and drilled into the bone where the cartilage was missing to create a little bit of bleeding, and the production, hopefully, fibrocartilage in these areas where cartilage has been worn done. I then made a through-and-through V-shaped osteotomy from medial-to-lateral in the head of the first metatarsal. I made a second dorsal cut about 4 to 5 cm proximal to the first dorsal cut, effectively removing a block of bone. I then reduced the osteotomy site which allowed for slight plantar flexion of the head of the first metatarsal and some shortening by the length of the block of bone removed. There was good bone-to-bone fit once this was complete. I temporarily fixated with a 45 K-wire. I then permanently fixated it with a 3.5 mm cannulated screw. Temporary fixation was removed. The osteotomy site was found to be very stable with good correction of the length of the first metatarsal and also some plantar flexor changes to the head. I used a power rasp to smooth any rough osseous edges. I then irrigated the wound with normal sterile saline, closed the wound with 3.0 Vicryl and 2.0 Vicryl closing effectively the joint capsule and periosteal tissues around the first metatarsal. Subcutaneous tissues were closed using 3-0 Vicryl and the skin was closed in a running subcuticular suture fashion using 3-0 Vicryl and then augmented with Steri-Strips. I injected a cc of dexamethasone phosphate divided evenly about the heel and the first metatarsophalangeal joint. I then dressed all wounds with Adaptic, sterile 4x4 gauze, 3 inch Kling, and a mildly compressive Coban wrap. The pneumatic tourniquet was released after 61 minutes to reveal an instantaneous reflex hyperemia to digits 1 through 5 of the left foot. Estimated blood loss for this procedure was less than 10 cc. There were no specimens for Pathology. The patient tolerated the surgery and anesthesia without complication. She left the operating room for recovery with vital signs stable and neurovascular status intact.
