FAQs

What happens during my first visit?
If you are a new patient, you can expect to have a complete physical exam. You will also be asked detailed questions about your current problems and your past medical history, your current medications, allergies, your family history and other pertinent medical information. If you are taking medications, please bring a completed medical history form with you to your appointment. Once the physician has reviewed your medical information and completed the physical examination, a plan of care will be developed. You may need to be seen again in the office, be referred back to your family physician for follow-up care, or require additional testing. If additional tests are needed, we will assist you in scheduling these tests.
What if I need to schedule an endoscopic procedure?

An endoscopic procedure allows the physician to visualize a part of your gastrointestinal tract with a special instrument called an endoscope. If your family physician has ordered testing, you will be contacted by telephone by one of our staff members. If a physician orders testing and you are in the office, the procedure can generally be scheduled during the course of your visit. You will be given a date, time, and location for the test, as well as written instructions telling you how to prepare for the test. If you have any questions about the procedure, please feel free to ask one of our staff members or the physician.

How do I get test results?

We ask that you wait 10 to 14 days before contacting us for results. Often results come from several different sources. This information needs to be compiled and reviewed by your physician before you can be appropriately advised. 

What insurances do you accept?

We accept payment from most insurance companies including Medicare, Blue Cross/Blue Shield, Blue Care Network, Physicians Health Plan, Cofinity, Sparrow Professional Health Network, Medicaid, McLaren, Health Plus, and several others. Accepted insurances are subject to change at any time without notice.

If your insurance requires an authorization from your primary care physician, you may be asked to assist us in obtaining this authorization.

All patients are responsible for all copays and deductibles at the time of service.

If you have any questions regarding your benefits or insurance coverage, please contact our Billing Department at 248-844-9710.

What if I need to contact the doctor?

To contact your doctor during business hours please call our main number 248-844-9710. If you have an urgent need to speak with the doctor after hours, you will be rerouted to our after hours answering service, and your doctor will be paged. In the case of a medical emergency please proceed directly to the nearest hospital emergency room.
