Sharpens H30a from "billed Part B" to per-HCPCS, per-place-of-service post-exclusion billing — the per-claim recoupment unit.
The NDH manifest still serves the May release after 66 days. The CMS directory team published a scrape of 31,255 certified-EHR FHIR endpoints (HTI-1 bundles) with NPIs and states attached; 98.7% of NDH orgs carried zero endpoints in the April release. H45 pre-registered: the per-state coverage gap, computed from public data on both sides.
When AINPI crawled every distinct FHIR-REST host referenced by the CMS National Provider Directory (2,974 hosts, 2026-04-09 release, one probe per host), 2,539 of them (85.4%) returned a parseable CapabilityStatement. Th
Practitioner records in the CMS National Provider Directory deduplicate cleanly: 7,441,211 NPIs, zero excess rows. One person, one record.
The CMS National Provider Directory carries a telecom entry for nearly every active practitioner. Here is the complete breakdown of what kind, measured on the 2026-05-08 release across 7,196,385 active Practitioner recor
H44 — endpoint metadata coverage vs the HTE submission spec — published. Of the 9 endpoint fields the spec collects, 5 have no home in the NDH FHIR Endpoint profile (STU1); the extensions that could carry the others are 0% populated across all 114,071 FHIR-REST endpoints. Today the NDH knows an endpoint address and payload type (both 100%), and that is the whole record.
H43 — practitioner phone-number reachability — published. 7,195,270 of 7,196,385 active practitioners (99.98%) in the 2026-05-08 release carry a phone directly on the Practitioner record; the role/location traversal adds nothing; 1,115 have no phone on any resource. The pre-registered prior (phone on the location, NPPES-style) was rejected by the data.
H43 (practitioner phone-number reachability) published — resolves practitioner → phone across three FHIR paths (Practitioner.telecom, PractitionerRole.telecom, referenced Location.telecom). Result rejected the pre-registered prior: 99.98% of active practitioners carry a phone directly on the Practitioner record; the traversal adds nothing.
Provider data landscape (Karpathy-style treemap, 548 cells, 6 audit dimensions) becomes the homepage at /; choropleth moves to /map. REAL Health Providers Act audit framework published at /real-health-providers. Endpoint-liveness denominator clarification (host-level not practitioner-level).
Two coordinated releases: the homepage swaps to a Karpathy-style hierarchical treemap (548 cells, 6 audit dimensions, one per state × specialty) and a new policy brief maps every § 6220 obligation of the REAL Health Providers Act to the AINPI signal that measures it. The choropleth moves to /map.
99.98% of active practitioners carry a phone right on the Practitioner record.
