Sharpens H30a from "billed Part B" to per-HCPCS, per-place-of-service post-exclusion billing — the per-claim recoupment unit.
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.
Sharpened H30a to per-(NPI, HCPCS, place-of-service) detail. Cross-audit surfaced 4 strict-post-exclusion candidates nationally; primary-source verification confirms 1 (Eduardo Miranda MD, LEIE-excluded 2015, $880K Medicare Part B in CY 2023) and reveals 3 SAM-NPI-join false positives. H42 null result honestly framed.
508,064 PECOS-NPPES taxonomy mismatches nationally (27.31%). Under the 2026 verification rules, every one is a denial-risk flag.
30.38% behavioral-health PECOS-NPPES mismatch rate. 44,875 providers at automatic-denial risk under the 2026 verification rules.
255,700 NPIs enrolled in ≥2 US states. Some are telehealth; some are stale. Under 2026 rules, every one needs triage.
PECOS-as-authoritative workstream (H37-H39) shipped; all-states claims-side cross-audit (H29-H36) covers 50 states + DC + PR; map-first homepage and CMO-facing per-state surface.
Excluded providers were paid by Medicaid. AINPI quantifies how much — in context.
