When is your Medicare revalidation due?
CMS publishes every provider’s revalidation due date free, and almost nobody knows where to look. Type your NPI and read yours. Miss it and CMS can put a hold on your reimbursement or deactivate your billing privileges outright.
Why this date is worth knowing
Revalidation is the one deadline in revenue cycle that is set by federal regulation rather than by a payer’s discretion. Under 42 CFR 424.515 you resubmit and recertify your enrollment information every five years — every three for DMEPOS suppliers — and CMS may ask off-cycle as well.
What makes it expensive is the consequence. CMS’s own revalidation page says that failing to revalidate on time “could result in a hold on your Medicare reimbursement or deactivation of your Medicare billing privileges”. Deactivation is not a warning letter. Getting back on requires a complete new enrollment application, and the effective date that comes out of that is governed by the ordinary enrollment rules, not restored to where it was.
And the way practices miss it is entirely mundane. CMS posts due dates about seven months ahead and the contractor writes roughly three to four months out — to the address on the Medicare enrollment record. That is often an old address, and updating NPPES does not update it. The letter goes to a suite the practice left in 2021 and the first anyone hears of it is a remittance that stops.
What we do about it
A credentialing seat is one full-time person who keeps this calendar: revalidations, re-credentialing intervals, CAQH attestation, and the enrollment paperwork behind each. It is $2,200 per seat per month, published, one month minimum. Nothing on this page is gated behind that and the lookup does not ask who you are.
This is a research tool built on a public dataset, not enrollment advice. CMS’s list is a periodic snapshot and an enrollment record can change between refreshes, so confirm your date in PECOS before you act on it.
Questions
How often do I have to revalidate my Medicare enrollment?
Under 42 CFR 424.515, providers and suppliers other than DMEPOS suppliers must resubmit and recertify the accuracy of their Medicare enrollment information every five years. DMEPOS suppliers revalidate every three years. CMS can also request an off-cycle revalidation at its discretion, which is why the published date matters more than counting five years from your last one.
What actually happens if I miss the deadline?
CMS states that failing to revalidate on time "could result in a hold on your Medicare reimbursement or deactivation of your Medicare billing privileges". Deactivation is the serious one: reactivating requires a complete new enrollment application, and your effective date is then governed by the ordinary enrollment rules rather than restored to where it was.
When will CMS tell me?
CMS posts revalidation due dates about seven months in advance and the enrollment contractor sends a notice roughly three to four months before the date. The failure mode is mundane: the notice goes to the address on the Medicare enrollment record, which is frequently an old one, and updating NPPES does not update that record.
Where does this data come from, and how current is it?
The CMS Revalidation Due Date List, a free public dataset with no authentication and no license. It covers 2,440,081 NPIs. Of those, 233,499 carry an assigned due date and we keep the earliest per NPI, because a provider with several enrollments is bitten by whichever comes first. The remaining 2.2 million are enrolled with no date assigned yet, and the lookup says so rather than reporting them as missing. It is a snapshot published on a schedule, so confirm in PECOS before acting on it.
Why is my NPI not on the list?
Those are two different answers and the lookup separates them. If CMS lists the NPI but has not assigned a date, you are told exactly that — it means your window has not opened, and there is nothing to do today. If the NPI is not in the file at all, that usually means it is not enrolled in Medicare, or a digit is wrong.
Do I have to give you my email to see the answer?
No. There is no form beyond the NPI field, nothing is stored against you, and the answer is not held back behind a signup. If the tool is useful, use it and go.

The tool answers one question. A seat answers the queue.
Next step
A lapsed enrollment stops every claim behind it
A credentialing seat works revalidations, re-credentialing and CAQH attestation so a date never arrives unannounced.
