Nj Medical Exclusions MCP server

@pipeworx/nj-medical-exclusions

Screens a provider or business name, an NPI, or a Vendor ID against New Jersey's Medicaid provider exclusion/debarment list — the state-level counterpart to the federal HHS OIG LEIE for New Jersey specifically, and the sibling of ny-omig-exclusions, ca-medical-exclusions, tx-medical-exclusions, fl-medical-exclusions, pa-medical-exclusions, ga-medical-exclusions and oh-medical-exclusions.

Part of Pipeworx — an MCP gateway connecting AI agents to 1843+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

provider or business against the list. An NPI or Vendor ID match is an IDENTIFICATION; a name match is a CANDIDATE lead only (no date of birth in this data). Every match carries the published action (Debarment, Suspension, or Disqualification), the reason code/label, the debarring department/agency, and a currentlyexcluded flag DERIVED from the expiration date and permanent-debarment flag — null with statusunknown:true when neither signal is present, never a guess.

arguments, reports total rows, how many are currently excluded vs. ended vs. status-unknown, how many carry an NPI or Vendor ID, the distinct action types, and the oldest/newest effective dates. With year or a date range, counts how many exclusions took effect in that window (counted by effective_date, over the whole list, not a page).

• njmedicalexclusioncoverage(year?, startdate?, end_date?) — with no

Data sources

Services — Ineligible Provider List (Medical) — the state's debarment, suspension, and disqualification notices for entities and individuals excluded from the New Jersey Medicaid program. No login, no CAPTCHA.

• New Jersey Department of the Treasury, Division of Revenue and Enterprise

Notes

go back to 1976 and include providers whose debarment/suspension/ disqualification has since expired or been lifted.

• This is the "ever excluded" file, not "currently excluded only." Rows

and a home (Individual) street/city/state/ZIP for every row; neither is baked or served here, matching the field set the seven precedent state exclusion packs serve.

• No home address is served. The upstream carries both a business (Firm)

publish a single current-status field. Only a minority of rows carry an expiration date, and the Permanent Debarment flag is Y/N/blank. A row with neither signal reports status_unknown:true rather than an assumed still-active status.

this dataset's Individual Name field is Treasury's own combined display string ("LAST, FIRST MIDDLE (TITLE)"), with no separate first/last columns. Matching works on the combined string and the Firm Name field.

• No parsed first/last name split — unlike the TX/PA/NY precedent packs,

match is the more common identification path.

• Vendor ID is sparse — populated on a small minority of rows; an NPI

carries an implausible year ("4014"), kept and reported as published rather than silently corrected.

• One known upstream data-entry artifact: a single row's effective date

and rebuilds src/nj-ips-index-data.ts; re-run periodically and recommit. dataasof on every response says how stale the baked copy is.

• Refreshed by scripts/bake-index.mjs, which re-fetches the published file
