Answer: The correct Advance Beneficiary Notice of Noncoverage (ABN) form is CMS-R-131 (Exp. 01/31/2026).

ABN refresh: An ABN form is a written notification indicating that Medicare may refuse to cover or reimburse for services or items recommended by your doctor, healthcare provider, or supplier. You should use the ABN to inform the patient in advance about their potential financial responsibility for the services or items in question. By signing the ABN, the patient acknowledges their understanding that they may be responsible for payment if Medicare denies coverage. The ABN also ensures transparency and allows patients to make informed decisions regarding their healthcare and associated costs before treatment.

Remember: When you believe a service may not be covered, such as a screening colonoscopy that exceeds frequency limits, you must provide the patient with a copy of the signed ABN, and you should keep the original ABN on file.

The Centers for Medicare & Medicaid Services (CMS) offers additional guidelines for patients covered by both Medicare and Medicaid, known as dual-eligible beneficiaries. These patients cannot be charged for Medicare cost-sharing when they receive services under Medicare Part A or Part B.
