Consider the following statistics that support the claim that fecal incontinence is a hidden condition: – For 84% of patients with FI, the physician was unaware of the patient’s disorder1 – 65% of patients with severe or major FI which had an impact on the quality of life wanted help with their symptoms2 1.

Adverse Events The most common adverse events experienced during clinical studies included: • • • • • • • Pain at implant sites New pain Lead migration Infection Technical or device problems Adverse change in bowel or voiding function Undesirable stimulation or sensations Any of these may require additional surgery or cause return of symptoms. For additional safety information, please refer to the Important Safety Information on the last slide of this presentation. Patient Selection and Workup for the InterStim System Patient Selection • Sacral neuromodulation can benefit those patients who have: – Chronic fecal incontinence – Patients who may not be able to undergo a more invasive surgical procedure • One advantage of InterStim is the ability to evaluate the therapy before implant of the device – Note: tined lead test period is up to 14 days • Sacral neuromodulation is not appropriate for patients who: – Have not demonstrated an appropriate response to the evaluation – May require an MRI • Now FDA approved for MRI head scans under specific conditions* – Are unable to operate the neuromodulation device (patient programmer) – Are not appropriate candidates for surgery *For InterStim II and specific InterStim I systems. Refer to the labeling prior to an MRI head scan. Patient Workup • When assessing a patient with fecal incontinence for sacral neuromodulation, there are four areas to consider: – – – – Patient history Bowel diary Validated QOL questionnaires Physical exam and diagnostic testing Initial Assessment and Patient History • A detailed history of symptoms, related conditions, and lifestyle factors are essential to understanding a patient's fecal incontinence condition. • A detailed history includes:1 – Current bowel care and management including diet, fluid intake, medications affecting bowel functions – Severity of fecal incontinence – Previous and present lower gastrointestinal function and disorders – Co-morbidity/complication (e.g., urinary incontinence, autonomic dysreflexia, pressure sores, sexual dysfunction) – Previous obstetric and surgical history – Neurological diagnosis and functional level – Patient’s satisfaction, needs, restrictions and quality of life – Environmental factors and barriers and facilitators to independent bowel 1.

Neurology and Urodynamics. 29:231-240 (2010). Bowel Diary • Prior to the first visit, it may be useful to have the patient keep a record of their bowel episodes by using a bowel diary. • Self-monitored and includes: – – – – written record of the frequency of bowel episodes the amount of incontinence experienced, urgency stool description whether or not the episode happened while the patient was asleep. • Can also be used as a tool to identify a pattern of episodes which may assist in diagnosis. Validated Quality of Life Questionnaires • These tools can help you assess the impact of fecal incontinence on the patient’s lifestyle • In addition, determine and document the severity of FI. CCF (Wexner) FI Score FI QOL Score Physical Exam and Diagnostic Testing • Evaluation of defecation function generally requires a combination of two or more assessment techniques. • There is no single objective study that can definitively assess all aspects of anorectal function. • A variety of anorectal investigations can help to define structural or functional abnormalities of anorectal function. Diagnostic tools include: – – – – – – – Anorectal examination Anal sonography or endoanal ultrasound Barium defecography (or proctography) Pelvic MRI Anorectal manometry Colonoscopy Barium enema InterStim: Treatment Algorithm for FI Initial Evaluation Patient Improvement Conservative Treatment Failed Conservative Treatment •Diet Modification •Medication •Behavioral Therapy Continue as Appropriate InterStim Basic Evaluation Positive Negative InterStim System Implant Positive InterStim Advanced Evaluation Negative Consider Other Surgical Treatment http://professional.medtronic.com/pt/gastro/snm/edu/patient-selection/index.htm Incorporating the InterStim System into Your Practice Patient Resources • Patient information on InterStim System on Medtronic website: – http://www.medtronic.com/patients/bowelincontinence – Patient Education Materials and Video – Bowel Ambassador Program • Patient Therapy Guide/Patient Post-Op Instruction Sheets Medtronic Reimbursement Resources Medtronic has resources available to assist your practice with coding and reimbursement considerations: • Field Based Health Economics Managers (available for coding and reimbursement education, claims reviews, appeal assistance, meetings with facilities, etc.) • Coding Sheets (Procedural and Diagnosis) • Financial/Coding Models • Prior Authorization Guides and Sample Letters of Medical Necessity Reimbursement Coverage • The coverage profile for sacral nerve stimulation for fecal incontinence is developing: – Local Medicare Coverage confirmed in all states – Many commercial payers have coverage policies in place • Diagnosis code used: – 787.60 fecal incontinence • Same procedural codes (CPTs) used as for urinary control Medtronic provides this information for your convenience only.

Summary • Ask your patients about fecal incontinence - they won’t come out and tell you • Sacral Neuromodulation • Ability to test • Effective and durable therapy to treat chronic fecal incontinence • Strong clinical evidence • Reimbursement is generally favorable • Medtronic offers comprehensive support Important Safety Information InterStim® Therapy for Bowel Control is indicated for the treatment of chronic fecal incontinence in patients who have failed or are not candidates for more conservative treatments. Contraindications: Diathermy. Patients who have not demonstrated an appropriate response to test stimulation or are unable to operate the neurostimulator. Precautions/Adverse Events: Safety and effectiveness have not been established for bilateral stimulation; pregnancy, unborn fetus, and delivery; pediatric use under the age of 18; or for patients with progressive, systemic neurological diseases. The system may be affected by or adversely affect cardiac devices, electrocautery, defibrillators, ultrasonic equipment, radiation therapy, MRI, theft detectors/ screening devices. Adverse events include pain at the implant sites, new pain, lead migration, infection, technical or device problems, adverse change in bowel or voiding function, and undesirable stimulation or sensations, including jolting or shock sensations.
