Frequently Asked Questions:

Why do I have a statement sent to me before my insurance is billed?

Our statements are generated automatically every  week.  It may be that you receive a statement  prior to the time your insurance company actually  was notified of your visit.  In this circumstance you are not expected to send a payment unless you have not paid your copay or patient portion at the time of service.

What is a "Medicare Waiver" ?

There can be times where Medicare does not cover a test or procedure. Medicare will only pay for services that it determines to be "REASONABLE & NECESSARY" according to Section 1862(a)(1) of the Medicare Law. Your Thunderbird Internal Medicine physician may order lab tests which they feel are recommended for you but Medicare may deny payment for that service. If this service is denied for payment from Medicare, you, the patient, agree to be responsible for payment for these services personally and fully, in a timely manner.  See additional information on this page.
