How many providers are excluded by Maryland Medicaid?

The Maryland Medicaid exclusion list Fonteum mirrors holds 1,605 records, 265 of which carry an NPI. The list reflects the published source; reinstatements can lag.

Does a Maryland Medicaid exclusion appear on the federal OIG LEIE?

Not necessarily. State Medicaid exclusion lists and the federal LEIE overlap but are not identical — a state-excluded provider can be absent from the federal list. A complete screen checks both.

Screening aid, not a determination. The list mirrors the published source as-is; Fonteum does not adjudicate exclusions.
Reinstatements and corrections can lag the published file. Cross-check any single record against the publishing agency before acting on it.
NPI matching is exact. Names are shown as published by the agency; a state exclusion is separate from the federal OIG LEIE.
