THE PHYSICIANS AND STAFF OF
NORTHWEST INDIANA NEUROLOGICAL ASSOCIATES
WELCOME YOU
The information that follows is designed to answer many of the questions patients have. The more you know, the
more we can be of service. If there are any questions, however, please ask, since we do want to be of help to you.
Dr. Rozenfeld, Dr. Bayer, Dr. DeLeo, Dr. Akan, and Dr. Gupta are Neurologists, specialists in diseases of the nervous
system and muscles. Neurologists diagnose diseases and offer medical treatment; they are not surgeons.
Most patients seeing a Neurologist have been referred by their own physician for evaluation of particular problems.
After appropriate tests and the start of treatment, further care may be provided by the Neurologist, or by the patient’s family
doctor. In any case, your own physician will continue to care for any other problems you might have.
Our doctors are on staff at St. Catherine’s, St. Margaret’s (North & South Campus), and Munster Community
Hospital. EMG (Electromyography) and EEG (Electroencephalogram) tests are performed either in our office or the hospital.
CT Scans, MRIs and other complicated tests are usually performed in the hospital.
(More detailed information about Neurologists and Neurologic tests may be found at the end of this brochure.)
Appointments and Office Hours: The office is open Monday through Friday from 8:00 am- 5:00 pm.
Patients are seen on an appointment basis only. Our main office phone number is (219) 836-2995 and is answered by staff
from 9:00 am until 4:50 pm except for lunch hour, which is generally from noon until 1:00 pm. When we are unavailable to
answer the phone, our 24-hr.answering service will always pick up the line and offer to take a message or page a doctor for
you if there’s an emergency.
We will make every effort to honor your appointment time, and request that you extend the same courtesy to us. On
occasion, emergencies can cause delays, and whenever possible you will be informed of scheduling changes or delays. If
there is an emergency and your doctor is running late, we will offer to reschedule your appointment at a time that is
convenient for you. If you are running late, we will also attempt to fit you in as time allows but might have to reschedule your
appointment for another date and/or time.
Please remember that your appointment time has been set aside just for you. If for some reason you cannot keep
your appointment, please try to give us 24 hours notice, so that another patient may be seen at an earlier time.
As a patient in our office, please remember that more than one physician may be seeing patients in the office at the
same time. Therefore, if someone arrives after you but seems to be called in to see the doctor before you, it might be
because that person is seeing another physician, or is having a test. If you have waited longer than ½ hr. for your
appointment, please be sure to alert the front desk. Also, please make sure to check in at the front desk at each visit. If you
don’t check in, we won’t know if you’re here for your appointment.
Once you have seen one of our doctors, that particular physician will continue to care for you and will see you for your
follow-up visits. The same policy would apply if you happen to be hospitalized. However, the doctors will sometimes alternate
weekend, evening, and hospital call schedules. Therefore, if you are in the hospital, or in the emergency room, depending on
the call schedule you might see one of our other doctors. Please note that Dr. Pradeep V. Kalokhe shares our weekend call
schedule, although he is not an associate in our practice. Also, if you feel that you need to come into the office on an
emergency basis, and your particular physician does not have office hours that day, you will probably be able to see one of
our other neurologists on that particular day or your neurologist might be able to meet you in the emergency room.
Emergency Care: Our 24-hour answering service is available by phoning the office number. Please let the phone
ring at least 4 times and the answering service will pick up your call. The doctors will do their best to respond to your problem
promptly. In the event of an emergency, or a situation in which you are in doubt, go immediately to the emergency room of
the nearest hospital and ask them to contact Dr. Rozenfeld, Dr. Bayer, Dr. DeLeo, Dr. Akan, or Dr. Gupta.
Telephone Calls: All patients are encouraged to call with any non-emergency questions they may have concerning
their neurologic problems. These calls should be made during regular office hours. The best time to call is in the mornings
between 9:00 and 11:00.
Your questions are best answered when your medical records are available to your physician.
Since it would be most unfair to you, were the doctor to leave the exam room to answer every telephone call
immediately, the office staff has been trained to answer many of your questions. They will also relay your questions to the
doctor. On those days when the office is closed, the answering service will forward all messages to the doctor. In either
case, your call will be answered at the earliest opportunity. Many telephone calls can be avoided by having a member of the
family come in with the patient for their appointments with the Neurologist.
Prescriptions and Renewals: Prescriptions and authorizations for renewals are best provided during office hours,
when your records are readily available. Prescriptions for certain medications cannot be renewed over the telephone or if you
have not seen the doctor for an extended period of time. Medications for pain will not be renewed when the office is closed
and your chart is unavailable to the doctor. This policy is in your best interest, and is designed for your protection.
PLEASE READ THIS IMPORTANT LETTER
CONCERNING YOUR INSURANCE COVERAGE AND PAYMENT INFORMATION
Dear Patient:
We may, from time to time, recommend diagnostic tests or procedures, which are not covered by your insurer,
HMO or PPO unless authorized before the test or procedure is performed.
It is your responsibility to make sure that the authorization for the test or procedure has been granted.
In addition, please be aware that many insurer’s HMO’s or PPO’s will only cover your hospital stay at certain hospitals
and prior authorization for hospital admissions is usually required.
It is important that you be aware of your insurance company’s policies and knows which hospitals you may use.
Although we will work with you in seeking the necessary authorization, we cannot be held responsible for determining that the
authorization has been granted. Please understand that we work with over 800 different insurers, which makes it virtually
impossible for our office staff to remember the policies for each insurer.
Therefore, if your insurer, HMO or PPO has not notified you that it has authorized a specific test, procedure, or hospitalization,
you should contact your insurer, before a test or procedure is performed, or before you are admitted to a hospital.
We thank you for your understanding and cooperation in this matter.
Northwest Indiana Neurological Associates, P.C.
INSURANCE AND PAYMENT INFORMATION
At the end of your visit, you will receive a statement of charges. Our office policy is that payment is due at the time
services are rendered. Other arrangements can be made depending on special circumstances. If you wish, we will accept
your Visa or Master Card.
Our Physicians and Office Manager invite you to discuss with them any questions you might have regarding our
services or fees. We believe that the best medical service is based on a friendly, mutual understanding between the doctor
and the patient.
Insurance and Insurance Forms: Our insurance coordinator will be happy to help you file your claims for
reimbursement under whatever health insurance coverage plans you have. Payment for all services provided by this office is
the responsibility of the individual patient unless prior arrangements have been made through a particular insurance carrier or
if you are a member of a particular insurance plan with whom we have a contract.
Please remember that insurance is considered a method of reimbursing the patient for fees paid to the doctor, and is
not a substitute for payment. Some companies pay fixed allowances for certain procedures, and others pay a percentage of
the charge. It is your responsibility to pay the deductible amount, co-insurance, or any other balance not paid for by your
insurance company. It is also your responsibility to obtain any required preauthorizations from your Family Doctor or
PCP prior to seeing our Doctors. (We realize that this may seem a nuisance for you; it is also time-consuming for your
referring doctor and us. None of us appreciate the vast amount of paper work that has been thrust upon us all by the
insurance industry.)
If we participate in your particular insurance plan, we will automatically bill your insurance for you. Otherwise, our
office uses a specially designed super bill. This bill, when completed and signed by the doctor, need only be attached to your
regular claim form and sent off to your insurance company. Therefore, our secretaries and the doctors need not complete
your insurance form itself. You, however, must fill out your portion of your claim as required by your insurance carrier, so
that you are reimbursed as quickly as possible.
Please feel free to call the office during regular office hours with any questions you might have concerning your
insurance claims or your account.

WHAT IS A NEUROLOGIST ?
A neurologist is a physician who has specialized medical training in disorders affecting the nervous system.
The nervous system consists of the brain, spinal cord and nerves. Many muscle disorders are also considered within the
province of a neurologist. Pain problems, especially headaches, also fall within the neurologist’s field. Illness or injury may
affect the nervous system directly, or the nervous system may be involved as the result of disease of other parts of the body.
Examples of medical problems, which may lead to neurological complications, include diabetes, hypertension and cancers
elsewhere in the body. Some Neurological Disorders are Epilepsy, Neuritis, Brain and Spinal Cord Tumors, Multiple
Sclerosis, Parkinson’s Disease and Stroke. Myasthenia Gravis and Muscular Dystrophy are Primary Muscle Diseases
included among neurological disorders.
At present, neurologists are able to cure some of the diseases of the nervous system and offer symptomatic relief from
others. Advances in research continue to provide new treatments, which the neurologist will be able to offer his or her
patients in the future.
Neurologists see patients with a wide range of problems. These include headaches, dizziness, seizures, blackouts and sleep
disorders. Numbness of arms and legs are frequent symptoms of neurological disease. Neck, back and head problems
following injuries may also require neurological evaluation. Neurologists may work with psychiatrists, psychologists and
others to evaluate mental, emotional or behavioral disturbances. Every neurologist has had training in taking care of children;
however, some have had more training in this field, and thus may specialize in neurological disorders of children. A
neurologist is often called as a consultant for a patient in the hospital. For example, if a patient becomes confused, has
difficulty in thinking or has loss of memory, a neurologist may be called. Symptoms suggesting a stroke, episodes of
unconsciousness or a seizure indicate the need for neurological consultation. Indeed, the nervous system is vulnerable to
disorders or disease in almost every medical condition.
What Is A Consultation?
If your family physician is concerned that your symptoms may involve the nervous system, he or she may request a
specialized opinion. A neurological consultation consists of a history of your medical background, with special attention to
your present problems. The neurological examination will involve test of vision, strength, coordination, reflexes and sensation.
This will enable the neurologist to locate where in the nervous system your problem exists. The examination may indicate that
tests are required. These tests are necessary to help the neurologist confirm diagnoses, which may lead to specific
treatment. This may include referral to a surgeon. The neurologist does not perform surgery, although he or she may
continue to follow surgically treated patients and supervise the treatment of the patient’s neurological disorder. The consulting
neurologist may temporarily assume management of the patient because of his or her expertise in a particular area.
Do I Still Need My Family Physician?
Your family physician is in charge of your general health care, and he or she is aware of your total health needs. When the
neurological disorder is your major problem, the family physician may temporarily relinquish responsibility and the neurologist
becomes your primary physician. A report of your neurological consultation will always be sent to your referring physician. It
is possible for you to continue seeing your neurologist strictly for your neurological problems while relying on your family
physician for your total medical care. Please remember, that in order to assure the best possible health care for you and your
family, you should always inform the doctor if you are seeing one or more doctors, and what medications, if any, you are
currently taking.

NEUROLOGICAL TESTING

Electroencephalogram (EEG): Records the continual brain electrical activity, by means of electrodes applied to the
scalp. It is often used to help diagnose structural disease of the brain and episodes described as seizures, fainting,
blacking-out or falling out. It is painless and requires little preparation.

Evoked Potentials: Records the brain’s electrical response to visual, auditory, and sensory stimuli. They are useful in
many diseases of the spinal cord and brain to evaluate and diagnose symptoms of dizziness, numbness and tingling, as
well as certain visual disorders.

Electromyogram (EMG) and Nerve Conduction Velocity Studies (NCV): Measures and records electrical activity from
the muscle and nerves to investigate disorders of these structures. These may be helpful in patients who have symptoms
of pain, numbness, tingling or weakness. Because small needles are inserted into the muscle, and often-mild electrical
shocks are given to stimulate the nerve, slight discomfort might be experienced.

Computerized Tomography (CT) or Computerized Axial Tomography (CAT) Scans: Combines x-rays and
computers to construct pictures of the brain and back. These pictures can provide much information regarding disease
states in the brain and back. A CT Scan is painless. Dye may be injected in a vein.

Cerebral Spinal Fluid Analysis (Spinal Tap or Lumbar Puncture): After local anesthesia is administered, a needle is
inserted into the lower back and spinal fluid is withdrawn from the spinal canal. This test is often crucial in making a
diagnosis of an infectious, bleeding or tumor disorder of the brain or spinal cord. When dye or air is injected through the
needle, followed by x-rays of the spinal column, the procedure is then called a Myelogram. A myelogram may be helpful
in patients who have neck or back pains or suspected spinal tumors.

Arteriograms (Angiograms): This examination requires a needle or catheter to be inserted into a neck or groin artery to
inject a dye, which provides x-ray visualization of the neck and brain vessels.

Magnetic Resonance Imaging (MRI): Nuclear Magnetic Resonance Imaging is a new technique, which utilizes the
computer technology of CT Scanning with magnetic/radio frequency waves rather than radiation, and is therefore free
from biological hazard to human beings. MRI scanning has several advantages over CT scanning. MRI scanning can
often pick up certain details, which are not clearly visible in a CT Scan. Again, there is no exposure to radiation as in a
CT Scan and the procedure is painless.

Polysomnogram (Sleep Study): A Polysomnogram records and measures various brain and breathing and other body
activities, in order to help with the diagnosis and treatment of various sleep disorders. Testing requires an overnight stay
in a comfortable hotel-like setting within the hospital (Community Hospital or St.Catherine Hospital).
