New York State OMIG Medicaid provider exclusion screening — check a provider by name, NPI or license number against the NY Office of the Medicaid Inspector General’s exclusion list, the state-level counterpart to the federal HHS OIG LEIE (leie pack) for New York specifically.

Tools

• ny_omig_check_exclusion(name?, npi?, license?, limit?) — screens a provider against the ~9,100-row NY OMIG exclusion list. An NPI or license match is an identification (both are exact, provider-specific identifiers); a name match — even an exact one — is a candidate lead only, since OMIG’s list carries no date of birth or address to tell same-named providers apart.
• ny_omig_exclusion_coverage() — total exclusions held, how many carry an NPI or license number, provider-type diversity, the oldest/newest exclusion date, and OMIG’s own “data last updated” date for the baked copy this pack serves.

Auth

Keyless.

Data sources

• https://apps.omig.ny.gov/exclusions/tabdelimited.aspx — the full exclusion list as tab-delimited text (provider name, license number, NPI, provider type, exclusion effective date). No JSON/REST endpoint exists; this is the cleanest of OMIG’s export formats (vs. a 6.5MB HTML “formatted list” for the same ~9,100 rows).
• https://apps.omig.ny.gov/exclusions/shortlist.aspx — the “last 30 days” HTML page, fetched only for its cheap “Data was last updated” banner (45KB vs. 6.5MB for the full formatted list).
• https://apps.omig.ny.gov/exclusions/ex_search.aspx — OMIG’s own online search tool (up to 5 names at once), linked in every response as online_search_url for a caller who wants to verify directly.

Why this is baked, not a live proxy

OMIG publishes the list only as flat files. Per root CLAUDE.md’s standing rule for exactly this shape, the table (~9,117 rows, ~1.3MB as generated TypeScript) is baked by scripts/bake-index.mjs into src/ny-omig-index-data.ts, registered in workers/gateway/src/pack-baked-indexes.json, uploaded to KV at deploy, and injected into every call as args._bakedIndex — never a static module-scope import (fleet #2754: six packs doing that put ~48MB of retained heap into every gateway isolate and cost about one call in four as a Cloudflare 1102). A missing or malformed injection throws loudly rather than answering “not found” — see src/index.test.ts.

Re-run node mcps/ny-omig-exclusions/scripts/bake-index.mjs periodically to refresh the copy and recommit; data_as_of on every response says how stale it is relative to OMIG’s own “last updated” banner, so staleness is visible rather than silent.

What this data does NOT include

Every OMIG export — tab-delimited, Excel, and the HTML formatted list — carries only provider name, license number, NPI, provider type and the exclusion effective date. There is no exclusion reason, statutory authority or case citation in this data, unlike the federal LEIE’s statutory exclusion-type code. Per-record detail, if OMIG holds any, sits behind an ASP.NET VIEWSTATE postback tied to a freshly-loaded search session rather than a stable queryable endpoint, and was not pursued for this first cut. Every response says this plainly rather than inventing a field OMIG does not publish.

Reachability

Verified live 2026-10-07 from both a laptop curl and a throwaway wrangler dev --remote Worker on the prod account: identical 200 / 535,395 bytes from the Cloudflare edge on tabdelimited.aspx. Unlike oklahoma-code / utah-code / new-hampshire-code, this host needs no Supabase egress relay.
