What is an ABN and why is it required for certain tests?
An Advanced Beneficiary Notice (ABN) is a requirement by Medicare. The Medicare program pays for services only if it determines that the services are reasonable and necessary. Some tests are medically necessary only if the patient has certain medical conditions, symptoms or diseases. Medicare calls these “limited coverage tests”. The ABN is to help patients make an informed choice about whether or not they want to receive certain laboratory tests that have a likelihood of being denied. The patient will have financial responsibility for the testing if Medicare denies payment.
