CMS Order & Referring

CMS Order and Referring

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

Research-only
Source:CMS Order & Referring·Checked May 2026Open official source ↗

The CMS Order and Referring file is the list of NPIs eligible to order and refer in Medicare, with a Y/N eligibility flag per benefit category (Part B, DME, Home Health, Power Mobility Devices, Hospice). One row per NPI, with last and first name. NPI is carried verbatim; the entity-graph cross-link is deferred.

What Fonteum uses it for

How this source shows up on Fonteum.

Per-NPI Medicare order/refer eligibility, available via the read API and the dataset page. The NPI -> entity-graph link is a separate, gated follow-up — this source writes no entity rows — so eligibility does not yet render on individual provider profiles.

What this source does NOT mean

Order-and-refer eligibility is a Medicare administrative authorization — it does not indicate quality, outcomes, board certification, or appointment availability, and absence is not a negative quality signal. Eligibility is not a Fonteum assessment of the provider.

What this dataset answers

Research and data questions this source supports.

  • 01Check whether an NPI is eligible to order and refer in Medicare, by benefit category (Part B, DME, Home Health, Power Mobility Devices, Hospice).
  • 02Build a claims-integrity check that validates the ordering/referring NPI on a claim is eligible for that benefit.
  • 03Cross-reference order/refer eligibility against the OIG LEIE to surface eligible-but-excluded providers for compliance research.
  • 04Power a provider-data API that returns Medicare order/refer eligibility flags per NPI.

Limitations

What we can’t infer from this source.

  • Eligibility is a Medicare administrative flag, not a quality measurement.
  • NPI-keyed, but the entity-graph cross-link is deferred — eligibility does not render on individual provider profiles yet.
  • The file republishes roughly weekly; eligibility changes lag the live CSV by up to one publication cycle.
  • Absence from the file is not a negative signal — many providers are not order/refer-eligible by enrollment type.

Frequently asked

Common questions about CMS Order & Referring.

What is the CMS Order and Referring file?
It is the CMS list of NPIs eligible to order and refer in Medicare, with a Y/N eligibility flag per benefit category — Part B, Durable Medical Equipment, Home Health Agency, Power Mobility Devices, and Hospice. There is one row per NPI, with last and first name.
How often does it update and where is it published?
CMS republishes the file roughly weekly 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 2,008,019 order/refer-eligible providers.
Does eligibility render on provider profiles?
Not yet. Order/refer eligibility is available via the read API and the dataset page, but the NPI → entity-graph link is a separate, gated follow-up, so eligibility does not yet render on individual provider profiles.
Is order/refer eligibility a quality signal?
No. Eligibility is a Medicare administrative authorization. It does not indicate quality, outcomes, board certification, or appointment availability, and absence from the file is not a negative signal — many providers are not order/refer-eligible by enrollment type.
