Overview
The ABN is a notice given to beneficiaries in Original Medicare to convey that Medicare is not likely to provide coverage in a specific case. “Notifiers” include:
- Physicians, providers (including institutional providers like outpatient hospitals), practitioners, and suppliers paid under Part B (including independent laboratories);
- Hospice providers and religious non-medical health care institutions (RNHCIs) paid exclusively under Part A; and
- Home health agencies (HHAs) providing care under Part A or Part B.
Revisions
The ABN is a formal information collection subject to approval by the Executive Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (PRA).
The notice is subject to public comment and re-approval every 3 years. With the latest PRA submission, a change has been made to the ABN. In accordance with Title 18 of the Social Security Act, guidelines for Dual Eligible beneficiaries have been added to the ABN form instructions.

CMS recommends that notifiers remove the lettering labels from the blanks before issuing the ABN to beneficiaries.
Once the claim is adjudicated by both Medicare and Medicaid, providers may only charge the patient in the following circumstances:
- If the beneficiary has QMB coverage without full Medicaid coverage, the ABN could allow the provider to shift financial liability to the beneficiary per Medicare policy.
- If the beneficiary has full Medicaid coverage and Medicaid denies the claim (or will not pay because the provider does not participate in Medicaid), the ABN could allow the provider to shift financial liability to the beneficiary per Medicare policy, subject to any state laws that limit beneficiary liability.
