What is an ABN?

An Advance Beneficiary Notice (ABN) is a liability waiver that you receive when we believe Medicare may not cover medical services provided to you.

It gives a detailed explanation of diagnostic and treatment services and/or items that your doctor recommends, along with your fees for each item should Medicare not reimburse your care.

Why do I have to sign the ABN Medical Necessity Waiver?

The ABN waiver allows you to make an informed decision on whether or not to choose services or items that may not be covered by Medicare. We ensure that you understand what charges you may incur before proceeding with any treatment, so you aren’t surprised with a bill later.

What if my claim is denied?

If Medicare denies your claim, you can file an appeal with them. You will need to do this on the Medicare Summary Notice that you receive in the mail quarterly. The last page of the summary contains step-by-step directions for filing an appeal.
