Critical Update for Providers: New 2026 Medicare ABN Form Approved

In the world of Revenue Cycle Management (RCM), small administrative changes can have a big impact on your bottom line. On March 13, 2026, the Office of Management and Budget (OMB) officially approved the updated Medicare Advance Beneficiary Notice of Noncoverage (ABN), form CMS-R-131.

If your practice treats Medicare patients, ensuring you are using the correct and current form is vital for compliance and for legally securing patient financial responsibility when Medicare may not cover a service.

Here is everything you need to know about the transition, the deadlines, and where to download the new forms.

Understanding the Transition Period

While the previous version of the ABN form officially expired at the end of January 2026, CMS allowed providers to continue using it while the new documents were being finalized.

Now that the new CMS-R-131 form is approved and effective immediately, the clock is ticking on the grace period. Providers have until May 12, 2026, to phase out the old forms. If you issue an outdated ABN after this deadline, it may be considered invalid, leaving your practice financially responsible for denied claims.

What’s New in the 2026 Update?

The core function of the ABN remains the same, but the OMB has introduced a few quality-of-life improvements:

• Better Readability: The updated layout features improved readability and a cleaner design, making it easier for beneficiaries to understand their financial obligations.
• Language Accessibility: As always, the fully updated forms are readily available in both English and Spanish.

💡 RCM Pro Tip: After May 12, using an outdated ABN form could render the notice invalid. If Medicare denies the claim, you may be unable to bill the patient, leading to lost revenue and increased write-offs.

Action Plan for Your Practice

To avoid compliance issues or lost revenue, we recommend taking the following steps immediately:

1. Download the New Forms: Head to the official CMS Beneficiary Notices Initiative (BNI) webpage to download the latest English and Spanish versions.
2. Update Your EHR: If your Electronic Health Record (EHR) or billing software automatically generates ABNs, contact your vendor to ensure the template is updated before the May deadline.
3. Purge Old Paper Forms: If you keep physical copies at your front desk, recycle the old versions (exp. 01/31/2026) and print fresh batches of the new form.
4. Train Your Staff: Ensure your billing, clinical, and administrative teams are aware of the update and know to look for the new March 31, 2029, expiration date at the bottom of the form.
