California Medicaid exclusion list
California publishes its Medicaid exclusion list as a CSV file; 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: California Medi-Cal Suspended & Ineligible List.
Counts are from the published RosterProof dataset, refreshed weekly; the page re-reads them on load. Format: CSV · cadence: monthly · last change RosterProof observed: 2026-10-12.
What the federal gap means in California
Of the 23,465 active records on the California list, 59.7% 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 California exclusion matters to any payer or employer in any state. The earliest exclusion start date the agency publishes is 1972-07-01 and the most recent is 2026-10-19 (dates are shown exactly as published). 1,982 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 California list
- In the browser, no account: paste or upload NPIs on Screen my providers. Each NPI is checked against the California list and every other list at once; results download as CSV.
- By API:
POST /v1/screenwith NPIs, names or organizations; a free key allows 500 lookups a month. API documentation. - In your warehouse: the free Snowflake listing or the weekly CSV / Parquet download; filter
JURISDICTION = 'CA'inEXCLUSIONS_SCREENABLE. - 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 California list (and OIG's SSN-based search for LEIE matches).
