Medicare revalidation is the re-verification of your enrollment record every five years, and you do it through PECOS. The process is short when you start on time: find your due date on the Revalidation List, log in to PECOS, review and update your whole record, pay the fee if you’re an institutional provider, e-sign, and submit. Miss the deadline, though, and Medicare deactivates your billing privileges and won’t pay for the gap. This guide walks the steps and shows you how to avoid that.
What is Medicare Revalidation?
Medicare revalidation is a complete re-verification of the information in your Medicare enrollment record, done to confirm it’s still accurate. CMS puts it plainly: revalidation is re-enrollment. You’re not changing anything by choice, you’re proving your record is current so you can keep your billing privileges. Every actively enrolled provider has to do it.
It’s a renewal, not a new application, which makes it different from the initial enrollment process. If you’re enrolling in Medicare for the first time, that’s a different path, covered in our guides on how to enroll in Medicare as a provider and how to enroll in PECOS Medicare. This guide is for providers who are already enrolled and need to renew. Revalidation is one piece of the broader re-credentialing work that keeps every credential current, and it sits alongside the initial provider enrollment we handle for new providers.
How often do you revalidate Medicare?
Most providers and suppliers revalidate every five years. DMEPOS suppliers revalidate every three. CMS also keeps the right to ask for an off-cycle revalidation when it wants to verify something. Your due date generally stays with you from one cycle to the next, so once you know it, you can mark the next one five years ahead.
One detail worth holding onto: 2026 falls under what CMS calls Cycle 3 revalidation, which brings stricter data verification and less tolerance for outdated records. The bar for a clean revalidation is higher than it was a cycle ago, so the old habit of submitting whatever’s on file and hoping it clears is riskier now.
How to revalidate Medicare on PECOS, step by step
Six steps. The first one is the most important, because everything downstream depends on knowing your date.
Step 1: Find your revalidation due date
Go to the Medicare Revalidation List look-up tool on the CMS website and search by your NPI. If you’re due, the tool shows a specific due date, always the last day of a month. If you’re not due yet, it shows TBD. CMS posts due dates about seven months in advance. One small but real gotcha: when you enter your NPI, don’t leave a trailing space, because an extra space can return an inaccurate result.
Step 2: Log in to PECOS
Sign in to PECOS with your I&A credentials and multi-factor authentication. If you also got a revalidation letter, confirm which provider the request applies to, because in a group, the request targets specific providers. PECOS is the fastest way to revalidate, since it’s paperless and only shows you the sections relevant to your situation.
Step 3: Review and update your entire enrollment record
Revalidation covers your whole record, including the parts that didn’t change. Work through every section: practice locations, ownership and managing control, taxonomy, and every group or organization you reassign benefits to. Actively remove locations, suites, or affiliations you no longer use, because leaving an old one on can trigger a site visit failure. This is also where most of the verification scrutiny lands, so accuracy here is what keeps the application moving.
Step 4: Pay the application fee if you’re an institutional provider
Institutional providers and DMEPOS suppliers pay the application fee, 750 dollars in 2026, through the PECOS online fee tool, and you pay it before completing the application. Individual physicians and non-physician practitioners revalidating on the CMS-855I generally don’t pay it. If a fee applies, pay it through Pay.gov, then upload the receipt to PECOS.
Step 5: E-sign and submit to your MAC
Electronically sign the certification statement and submit. Your Medicare Administrative Contractor processes the revalidation. Make sure the email address on the application is current and that your spam filter won’t block MAC messages, because a missed request at this stage is how an on-time revalidation still ends in deactivation.
Step 6: Track status and respond to any development request
Track the application in PECOS using the enrollment status tool. If the MAC sends a development request for more information, respond carefully and on time, give them exactly what they asked for. Failure to respond to a development request is one of the most common ways a revalidation fails, and the result is deactivation.
What happens if you miss your revalidation deadline?
This is the part that makes revalidation worth taking seriously. If you don’t submit a complete revalidation by your due date, the consequences come in sequence:
- Payment hold. Your MAC first places a hold on your Medicare payments.
- If you still haven’t submitted, your billing privileges are deactivated, typically 60 to 75 days after the due date.
- No payment for the gap. Unlike initial enrollment, where some retroactive billing is allowed, Medicare does not pay for services provided during a deactivation caused by a missed revalidation. That revenue is gone.
- Reactivation is a full re-enrollment. To get billing privileges back, you submit a new, complete enrollment application, and the MAC can take 60 to 90 days to process it. Your Medicare revenue stays frozen the whole time.
Put simply, a missed revalidation can freeze your Medicare cash flow for months over a deadline you knew about five years in advance. That’s why this is a tracking problem, not a paperwork problem.
How to avoid a revalidation deactivation
The notice system isn’t enough to rely on. Your MAC sends a revalidation notice about three to four months before your due date, but if your contact information in PECOS went stale over five years, which happens constantly, that notice may never reach you. CMS is explicit that tracking your due date is your responsibility, notice or no notice.
What actually prevents deactivation:
- Check the Revalidation List tool periodically rather than waiting for a letter
- Start the revalidation about six months before the due date, early enough to handle a development request without pressure
- Keep your PECOS contact email current so MAC messages reach you
- Confirm your NPPES record still matches PECOS before you submit
- Track all your providers’ due dates centrally, since a group has many on different dates
That last point is where practices struggle most. One provider can track one date. A growing group tracking a dozen revalidations, alongside CAQH re-attestations and commercial re-credentialing, is where dates start slipping. Managing those overlapping cycles is exactly what our re-credentialing services exist to do.

Revalidation mistakes that cause deactivation
| Mistake | What it causes | How to avoid it |
|---|---|---|
| Not tracking the due date | Missed deadline, deactivation | Check the Revalidation List tool, don’t wait for a letter |
| Stale PECOS contact email | MAC notice never arrives | Keep the contact email current in PECOS |
| Submitting too early | Application returned as unsolicited | Submit about six months before the due date |
| Old practice locations left on | Site visit failure | Remove locations you no longer use |
| Ignoring a development request | Deactivation for non response | Respond promptly with exactly what’s asked |
| NPPES and PECOS mismatch | Rejection, delay | Align the records before submitting |
Frequently Asked Questions
How do I find my Medicare revalidation due date?
Search the Medicare Revalidation List look-up tool on the CMS website by your NPI. If you’re due, the tool shows a specific due date, always the last day of a month. If you’re not due yet, it shows TBD. CMS posts due dates about seven months in advance. When you search by NPI, don’t include a trailing space, since that can return an inaccurate result.
How often do I have to revalidate Medicare?
Most providers and suppliers revalidate every five years, and DMEPOS suppliers revalidate every three years. CMS also reserves the right to request off-cycle revalidations. Your due date generally stays with you across cycles, so once you know it, you can plan the next one five years out.
What happens if I miss my Medicare revalidation deadline?
If you don’t submit a complete revalidation by the due date, your MAC places a hold on your Medicare payments and then deactivates your billing privileges, typically 60 to 75 days after the due date. Medicare does not pay for services during a deactivation gap caused by a missed revalidation, and that revenue is not recoverable. Reactivation requires a new, complete enrollment application.
Does Medicare send a reminder before revalidation is due?
Yes. Your MAC sends a revalidation notice by email or mail about three to four months before your due date. But you can’t rely on it, because if your contact information in PECOS is outdated, which is common over five years, the notice may never reach you. CMS makes clear you’re responsible for tracking your own due date regardless of the notice.
Do I have to pay a fee to revalidate Medicare?
Institutional providers and DMEPOS suppliers pay the application fee, which is 750 dollars in 2026, through the PECOS online fee tool before submitting. Individual physicians and non-physician practitioners revalidating on the CMS-855I generally do not pay the fee. Pay before completing the application and upload the receipt to PECOS.
Can I revalidate too early?
Yes, and it backfires. If you submit a revalidation application more than about seven months before your due date, the MAC returns it as unsolicited. The right window is to submit within the months leading up to your due date, ideally early enough to handle any development request comfortably. Submitting six months out is a safe target for most providers.
