An exclusion, revocation, or suspension refers to actions taken against an individual or entity that prevents them from participating in Medicare, Medicaid, or other Federal health care programs. These actions are typically taken when there is evidence of past or present program violations. A debarment, on the other hand, is a more severe action that prohibits an individual or entity from contracting or participating in any Federal program or receiving Federal financial assistance. Debarment is usually imposed for more serious or repeated violations.
