Advance Beneficiary Notice (ABN)
An Advance Beneficiary Notice (ABN) is a written notice a provider gives a Medicare patient before delivering a service Medicare is likely to deny, informing them they may be financially responsible. Surgery centers use ABNs to protect billing rights on non-covered procedures.
What is an Advance Beneficiary Notice (ABN)?
An Advance Beneficiary Notice (ABN) is a written notice a provider gives a Medicare patient before delivering a service that Medicare is expected to deny or consider not medically necessary. It informs the patient in advance that they may be personally responsible for the cost.
The notice describes the specific service, the reason Medicare is likely to decline payment, and the estimated cost, allowing the patient to make an informed choice about whether to proceed and accept financial responsibility.
Why does it matter for billing?
A properly issued ABN preserves the provider's right to bill the patient if Medicare denies the claim. Without it, the provider generally cannot hold the patient responsible for a non-covered service and must absorb the loss.
Surgery centers use ABNs when a scheduled procedure or item may fall outside Medicare coverage, protecting their ability to collect while keeping the patient informed. Issuing the notice correctly and at the right time is what makes that protection valid.
