CMS Revalidation

CMS Medicare Revalidation Due Date List

Centers for Medicare & Medicaid Services (CMS) · Tier-2 · profile-enrichment (renders on matched profiles)

Research-only
Source:CMS Revalidation·Checked May 2026Open official source ↗

The CMS Revalidation Due Date List publishes when each Medicare-enrolled provider must revalidate enrollment under 42 CFR 424.515 (ACA §6401(a)). The natural key is the pair (enrollment id, NPI): an enrollment id can carry several NPIs for organization enrollments. Each row carries name, organization, state, enrollment type, specialty, and the revalidation due date.

What Fonteum uses it for

How this source shows up on Fonteum.

Per-enrollment Medicare revalidation due dates, available via the read API and the dataset page. The NPI -> entity-graph link is a separate, gated follow-up — this source stores revalidation records, not resolved provider-graph entities — so it does not yet render on individual provider profiles.

What this source does NOT mean

A revalidation due date is a Medicare enrollment-administration deadline — it does not indicate quality, outcomes, or any disciplinary status. A 'TBD' or absent date means CMS has not set a due date, not that the provider is non-compliant; it is not a Fonteum assessment.

What this dataset answers

Research and data questions this source supports.

  • 01Look up when a Medicare-enrolled provider or organization must revalidate enrollment, by enrollment id and NPI.
  • 02Build an enrollment-operations dashboard that surfaces upcoming revalidation deadlines for a provider network.
  • 03Research revalidation due-date distribution by enrollment type and state.
  • 04Power a provider-data API that returns the revalidation due date per enrollment.

Dataset size: 2,900,588 enrollment records (2026-06-14 snapshot)

Fields used

Every field below has a `display_allowed` flag in the §94 provenance schema. Write-locked fields are captured to provenance for audit but never rendered on profile pages.

Limitations

What we can’t infer from this source.

  • A revalidation due date is an enrollment-administration deadline, not a quality or compliance signal.
  • Upstream 'TBD' / blank values are stored as null — an absent date means no due date is set, not non-compliance.
  • NPI-keyed where present, but the entity-graph cross-link is deferred — due dates do not render on individual provider profiles yet.
  • Snapshot-based: a row republished after the monthly snapshot does not appear until the next pull.

ToS & usage notes

What the source allows.

U.S. government public-domain works. CMS publishes the Revalidation Due Date List as a no-auth bulk CSV at data.cms.gov with explicit redistribution rights. Fonteum resolves the live release-dated CSV by the stable dataset UUID and attests each snapshot.

Sample provenance

Frequently asked

Common questions about CMS Revalidation.

What is the CMS Revalidation Due Date List?
It publishes when each Medicare-enrolled provider must revalidate enrollment under 42 CFR 424.515 (ACA §6401(a)). The natural key is the pair (enrollment id, NPI) — an enrollment id can carry several NPIs for organization enrollments. Each row carries name, organization, state, enrollment type, specialty, and the revalidation due date.
What does a 'TBD' or blank due date mean?
It means CMS has not set a revalidation due date for that enrollment yet. Fonteum stores upstream 'TBD' / blank values as null — an absent date is not a sign of non-compliance.
How often is the list published?
CMS republishes the list monthly at data.cms.gov as a no-auth bulk CSV under a release-dated path. Fonteum resolves the live CSV by the stable dataset UUID and attests each snapshot. As of the 2026-06-14 snapshot, Fonteum holds 2,900,588 enrollment records.
Is a revalidation due date a compliance or quality signal?
No. It is an enrollment-administration deadline. It does not indicate quality, outcomes, or any disciplinary status, and it is not a Fonteum assessment of the provider.
Does this render on provider profiles?
Not yet. Due dates are available via the read API and the dataset page, but the NPI → entity-graph link is deferred, so they do not yet render on individual provider profiles.
