Medicare
Original Medicare
Original Medicare provides broad provider access nationwide with no referrals required but lacks an out-of-pocket maximum, making supplemental coverage important.

Definition
Original Medicare refers to the traditional fee-for-service Medicare program operated directly by the federal government under the Centers for Medicare & Medicaid Services (CMS), consisting of Part A (hospital insurance) and Part B (medical insurance). Unlike Medicare Advantage, Original Medicare is not offered by private insurers — it is administered directly by CMS and paid for through federal funds and beneficiary premiums. Original Medicare allows beneficiaries to see any doctor, specialist, or hospital that accepts Medicare nationwide, without referrals and without network restrictions, providing maximum provider flexibility. The significant limitation of Original Medicare is the absence of an annual out-of-pocket maximum: because Part B cost-sharing is 20% of Medicare-approved amounts with no cap, a catastrophic illness can result in unlimited patient liability. This gap is the primary reason most Original Medicare beneficiaries purchase Medigap (Medicare Supplement Insurance) to cap their exposure. Original Medicare does not include prescription drug coverage — beneficiaries must add a stand-alone Part D plan for drug benefits.
