The National Plan and Provider Enumeration System is the registry every healthcare provider in the United States must join to bill insurance. It is public domain, it is enormous, and it is published as a 9 GB text file that almost nobody reads. This site keeps a current copy and makes it answerable.

Every provider on this site is registered with CMS. That is not the same as practising: the registry has no field for retirement, and a record only disappears when someone deactivates it, which many never do. A practice address tells you where a clinician is based, not everywhere they are licensed — someone practising by video may hold licences in a dozen states and appear here under one.
What it is very good for is counting. How many of a specialty exist, where they are, how that has changed, and which places have almost none. That is what Data Labs does.
Free API
Everything here is available as JSON, including a delta feed designed for keeping your own copy in step.
Four ways to use the registry
Everything is built on the same monthly federal data. What differs is whether you want to watch it, read it, browse it or query it.
Provider Radar
Watch a place and a specialty. Every clinician who registers there lands in your list, and a digest tells you what is new. Fifteen stackable filters, and a filter set is a shareable link.
MonitoringPractice Radar
The same for organisations — new groups, clinics and practices registering in an area, before they appear anywhere else.
AnalysisData Labs
Ten published analyses of the registry: where nurse practitioners are displacing physicians, which addresses hold hundreds of providers, what physicians earn by specialty and metro.
AnalysisMedical salaries
Physician pay by specialty, state and metro, from four public sources, with a confidence grade on every figure and fifteen years of history in real terms.
DirectorySpecialty directory
All 861 taxonomies in use, each with counts by state and city, and a page for every specialty in every state with enough providers to be worth reading.
DevelopersAPI
JSON over the whole registry, a delta feed for what changed, and a free tier. The same data the site runs on, with no scraping.
Browsing is free. Extraction is paid.
The registry is public domain, so search and reading stay open to everyone. What costs money is taking data out in bulk — exports, saved monitoring and the API.
