Missed Your Medicare Revalidation Due Date? What Happens Next

Published October 5, 2026

If your Medicare revalidation due date has passed, or is about to, you are not out of Medicare yet. But the outcomes that follow cost money, and deactivation takes away payment for every day it lasts. Here is what CMS can do, the clocks that apply, and how to get back.

First, confirm the date

CMS posts revalidation due dates on the Medicare Revalidation List, seven months in advance. Your contractor sends a notice by email or mail about three to four months before the due date, but you are responsible for tracking the date yourself. (Source: CMS: Revalidations (Renewing Your Enrollment).) CMS does not grant extensions and there are no exemptions from revalidation. (Source: CMS: Revalidations (Renewing Your Enrollment).) If you are within three months of the due date, revalidate even if no notice arrived. (Source: CMS: Revalidations (Renewing Your Enrollment).)

The clocks in the regulations

Outcome 1: a stay of enrollment

CMS may stay your enrollment if you are out of compliance and can fix it with a change of information or revalidation application, which includes a revalidation application that was rejected. During a stay you remain enrolled, but claims with dates of service in the stay period are rejected. They become payable, and can be resubmitted, if you resume compliance before the stay period ends. A stay lasts at most 60 days. (Source: 42 CFR 424.541, stay of enrollment, (a).) CMS describes this as a possible "hold on your Medicare reimbursement." (Source: CMS: Revalidations (Renewing Your Enrollment).)

Outcome 2: deactivation

Deactivation stops your billing privileges. The effective date can be set back to the date you became non-compliant, not just the date CMS acts. (Source: 42 CFR 424.540, deactivation of Medicare billing privileges, (d)(1)(ii)(A).) You may not receive payment for services furnished while deactivated. (Source: 42 CFR 424.540, deactivation of Medicare billing privileges, (e).) Deactivation does not affect a provider agreement or conditions of participation. (Source: 42 CFR 424.540, deactivation of Medicare billing privileges, (c).)

Reactivation, and why it does not reach back

To reactivate, you recertify that your enrollment information is correct, furnish anything missing, and meet all enrollment requirements. CMS may require a complete Form CMS-855 application. (Source: 42 CFR 424.540, deactivation of Medicare billing privileges, (b).) On its revalidation page, CMS says that after a deactivation you will need to re-submit a complete enrollment application. (Source: CMS: Revalidations (Renewing Your Enrollment).)

The reactivation is effective on the date the contractor received the reactivation submission that was processed to approval. (Source: 42 CFR 424.540, deactivation of Medicare billing privileges, (d)(2).) CMS puts it plainly: "Medicare won't reimburse you for any services during the period that you were deactivated." (Source: CMS: Revalidations (Renewing Your Enrollment).) Every day between the deactivation date and the date your complete submission is received is a day you cannot bill for. That is why speed matters more than anything else here.

Outcome 3: revocation

Revocation ends enrollment. CMS may revoke for noncompliance with enrollment requirements, and the rule specifically covers revocations based on a failure to respond timely to a revalidation request. (Source: 42 CFR 424.535, revocation of enrollment, (a)(1) and (c)(1)(ii).) In that case the reenrollment bar, which otherwise lasts from 1 to 10 years apart from listed exceptions, does not apply. (Source: 42 CFR 424.535, revocation of enrollment, (c)(1).) A revocation is effective 30 days after the notice is mailed, apart from listed exceptions, and to come back you enroll again as a new provider with a new application. (Source: 42 CFR 424.535, revocation of enrollment, (g)(1) and (d)(1).)

What to do now

1. Look up your due date on the Medicare Revalidation List and read any letter or email from your contractor.
2. If you have a notice, a rejection, a stay or a deactivation letter, note its date. The 15-day rebuttal window runs from it.
3. Submit a complete revalidation in PECOS now. An incomplete one starts a new problem: missing information can bring a 30-day request and, if it goes unanswered, a rejection. (Source: 42 CFR 424.525, rejection of an enrollment application, (a)(1).)
4. Do not submit if there is no due date on the list and no request from your contractor: CMS says those are returned. (Source: CMS MLN9658742, Medicare Provider Enrollment (December 2025).)
