Medicare revalidation

Every Medicare enrollment has to be revalidated on a schedule. Missing the date can stop Medicare payments, and CMS does not grant extensions.

Checked against each source on October 12, 2026. Rules change, so confirm with the payer or agency before you file.

How often, and how to find the date

• Every five years for most. "In general, providers and suppliers revalidate every five years but DMEPOS suppliers revalidate every three years." The regulation: a provider or supplier "must resubmit and recertify the accuracy of its enrollment information every 5 years."
• Look it up. "You can search the Medicare Revalidation List to find a due date for an individual or organizational provider." CMS "posts revalidation due dates seven months in advance."
• Notice. Your Medicare contractor sends a revalidation notice "about three to four months prior to your due date."
• Timing. CMS says to submit once you're within three months of the due date, even without a notice, and that submissions more than seven months early without a notice "will be returned."

If you miss it

• CMS: "Failing to revalidate on time could result in a hold on your Medicare reimbursement or deactivation of your Medicare billing privileges."
• "There are no exemptions from revalidation. Additionally, CMS doesn't grant extensions."
• If deactivated, "you'll need to re-submit a complete Medicare enrollment application," and "Medicare won't reimburse you for any services during the period that you were deactivated."
• If the contractor asks for more documentation, CMS says to respond within 30 days.

Groups and clinicians each have a date

A group's enrollment and each clinician's enrollment are revalidated separately, so check every one. We revalidate groups for a flat fee, and Upkeep tracks every date so none slips.
