Wyoming Medicaid exclusion list

Wyoming Medicaid Provider Exclusion List · in the RosterProof dataset · as of 2026-10-29

Wyoming publishes its Medicaid exclusion list as a PDF; the agency updates it monthly. RosterProof loads it every week into the same schema as the federal OIG LEIE, SAM.gov and 41 other state lists, resolves names to NPIs where the national registry confirms them, and keeps every change. The official list is the record of truth: Wyoming Medicaid Provider Exclusion List.

What the federal gap means in Wyoming

Of the 118 active records on the Wyoming list, 61% do not appear on the federal OIG LEIE. A program that screens only the federal lists, as 42 CFR 455.436 requires at minimum, never sees those providers. Under ACA §6501, an exclusion or for-cause termination in one state's Medicaid program is grounds for termination in every other state, so a Wyoming exclusion matters to any payer or employer in any state. The earliest exclusion start date the agency publishes is 2000-02-20 and the most recent is 2025-03-20. 10 of the records belong to providers that at least one other jurisdiction has also excluded. How the gap is measured, for every state: The federal gap, measured.

How to check a provider against the Wyoming list

  1. In the browser, no account: paste or upload NPIs on Screen my providers. Each NPI is checked against the Wyoming list and every other list at once; results download as CSV.
  2. By API: POST /v1/screen with NPIs, names or organizations; a free key allows 500 lookups a month. API documentation.
  3. In your warehouse: the free Snowflake listing or the weekly CSV / Parquet download; filter JURISDICTION = 'WY' in EXCLUSIONS_SCREENABLE.
  4. Then confirm with the agency. A hit identifies a published record and, where present, an NPI match with a stated confidence. Before any adverse action, verify against the official Wyoming list (and OIG's SSN-based search for LEIE matches).
