According to the Centers for Medicare & Medicaid Services (CMS), the National Plan and Provider Enumeration System (NPPES) listed 7,056,332 active National Provider Identifiers as of the May 2026 release — the most comprehensive public registry of U.S. healthcare providers. PlainDoctor mirrors that federal dataset in full, attaches each clinician's Medicare Part D prescribing and MIPS quality record where it exists, and never adds a proprietary rating. Full sourcing, refresh cadence, and documented limitations are in the methodology.

Frequently asked questions
How do I look up a healthcare provider by name? +
Use the name search at the top of this directory, or browse by specialty or state below. Every record is keyed to the provider's National Provider Identifier (NPI) — the 10-digit HIPAA-standard ID that CMS issues at enrollment — so each of the 7.06M clinicians resolves to a single, unambiguous profile.
Is this the official CMS provider directory? +
No. PlainDoctor is an independent directory built directly from public CMS data — the National Plan and Provider Enumeration System (NPPES), Medicare Part D prescriber files, MIPS quality scores, and Open Payments. We publish the federal records verbatim with no proprietary rating; CMS remains the system of record, and corrections must be filed with NPPES.
What does a doctor provider number (NPI / PTAN) tell me? +
The NPI is the national identifier every clinician carries across insurers and states. Each PlainDoctor provider page shows the NPI, the NUCC taxonomy (primary specialty), enumeration date, and practice location — the same fields payers use to verify a provider. PlainDoctor does not publish PTANs, which are Medicare-enrollment numbers private to the provider and their administrative contractor.
How current is the provider data? +
The NPPES registry is mirrored on a monthly cadence aligned with the CMS bulk-data release; Part D, MIPS, and Open Payments reflect the most recent CMS publication year. Each release replaces the prior mirror in full — NPPES publishes no delta file — so a clinician who deactivates between snapshots remains listed until the next monthly refresh.
Methodology & sources
This directory is compiled from the CMS National Plan and Provider Enumeration System (NPPES), refreshed monthly from the CMS bulk-data release. Every clinician is uniquely identified by their National Provider Identifier (NPI), classified by a self-selected NUCC Health Care Provider Taxonomy code, and attributed to a state by their self-reported practice address. Prescribing data is drawn from CMS Medicare Part D, quality scores from CMS MIPS, and industry payments from CMS Open Payments.
Counts are point-in-time snapshots published exactly as CMS releases them, with no editorial ranking or proprietary score. See the full methodology for the pipeline, coverage, and documented limitations.
