Funding Medicare: Exploring the Sources and Expenses
Medicare Part B, a crucial federal healthcare program, provides medical care coverage for adults aged 65 and older, adults with disabilities, and people with end-stage renal disease (ESRD). Beyond the funding from the Federal Insurance Contributions Act (FICA) taxes, Medicare Part B in the United States is additionally funded by a combination of beneficiary premiums, transfers from general federal tax revenues, and federal funding supporting state Medicaid-administered Medicare Savings Programs (MSPs).
The primary source of funding for Medicare Part B is the monthly premiums paid by most enrollees. For instance, the standard base premium in 2025 stands at $185 per month per person. These premium revenues contribute directly to funding Part B benefits.
General federal tax revenues also play a significant role in Medicare funding. These revenues provide nearly half of Medicare spending, including for Part B and Part D coverage. This means that congressional appropriations from the overall federal budget help finance Medicare Part B costs.
Furthermore, state-run Medicare Savings Programs (MSPs) indirectly supplement Medicare financing. While MSPs primarily assist low-income beneficiaries by paying their Part A and Part B premiums and certain out-of-pocket costs, the federal government funds these programs based on state Medicaid programs.
In 2023, Medicare expenditures totaled $1,029.8 billion, with the hospital insurance (HI) trust fund spending $403.1 billion on Part A services and administrative expenses. The Part B deductible for 2025 is $257, a $17 increase from 2024. For an annual income of at least $500,000, the maximum monthly premium for Medicare Part B is $628.90.
It is important to note that the 2024 Medicare Trustees Report indicates that it is difficult to predict future Medicare costs due to uncertainties in changes and advances in technology and medicine. Despite these uncertainties, the funding structure of Medicare Part B remains a combination of FICA taxes, beneficiary premiums, general federal tax revenues, and state-run Medicare Savings Programs.
