Methodology
Every fact on this site traces back to a public government file. This page describes the pipeline, in plain terms.
Source
Our sole provider-data source is the NPPES Data Dissemination file, published monthly by the US Centers for Medicare & Medicaid Services (CMS). The current site build uses the June 2026 file. Specialty names and definitions follow the NUCC Health Care Provider Taxonomy code set.
Scope of this release
We include individual providers (NPI Type 1) whose primary practice address is in Texas and whose taxonomy identifies them as a nurse practitioner or physician assistant: 55,346 providers, 40,840 NPs and 14,506 PAs, across 865 cities. Organizations, other professions, and other states are not yet included.
Update cadence
CMS publishes a full NPPES file every month; we rebuild the site from each new file. Changes providers make in NPPES therefore appear here within roughly one month. Each profile shows both the file month and the date NPPES last updated that record.
What we derive
- City and specialty counts, and city ranks within Texas.
- “At this location” lists: providers whose records share the same street address, city, and ZIP.
- Years in the registry, computed from the NPI enumeration date.
- Plain-English specialty explainers, written by us, alongside the official NUCC classification.
Derivations are deterministic arithmetic on the source records. We do not infer, estimate, or generate facts.
Accuracy disclaimer
NPPES content is self-reported by providers and can lag reality: providers move, retire, or change phone numbers without updating the registry. A listing here is not proof of current licensure or practice, and nothing on this site is medical advice. Verify independently before care or credentialing decisions, and report record errors through the process on our corrections page. Questions: contact@npiatlas.com.
