Federally Excluded Providers in Colorado Carrier Networks

These providers appear on the OIG List of Excluded Individuals/Entities (LEIE) and/or the SAM.gov exclusion list, yet are still listed as in-network by one or more Colorado health insurance carriers.

Why This Matters

Providers on the OIG LEIE or SAM.gov exclusion list are federally prohibited from participating in Medicare, Medicaid, and all federal healthcare programs. When a carrier lists an excluded provider in their network directory, it creates multiple risks:

  • Compliance violation: Carriers and employers who contract with excluded providers may face Civil Monetary Penalties (CMPs) under the Social Security Act.
  • Patient safety: Exclusions are typically triggered by fraud convictions, patient abuse, license revocations, or other serious misconduct.
  • Claims liability: Services rendered by excluded providers are not reimbursable by federal healthcare programs.
