The OIG Exclusion List is a registry of individuals and entities that have been excluded from participation in Federal health care programs. Exclusion may be mandatory in nature or permissive, depending based on the underlying adverse action.

The CMS Preclusion List is a registry of all health care providers, suppliers, and prescribers who are precluded from receiving reimbursement for Part C Medicare Advantage items and services or Part D drugs that are provided or prescribed to Medicare beneficiaries.

II. Purpose

If a health care provider, supplier, or other entity is on the OIG Exclusion LIST, the excluded party cannot provide care or services to Medicare and / or Medicaid beneficiaries. Nor can the excluded party work for a participating provider or serve as an agent, contractor, or vendor for participating provider or supplier.

The CMS Preclusion List was implemented to better ensure patient safety and to protect the integrity of the Medicare Trust Funds from the actions of providers and prescribers that have been identified as “BAD ACTORS.”
