Medicare is a key social insurance program that provides health coverage to 59 million older adults and people with disabilities in the U.S. But where does the financing for Medicare come from and what is the Medicare trust fund? This article will explain what trust funds support Medicare and how the different parts of Medicare are funded.
Overview of Medicare
Medicare is the national health insurance program primarily for Americans aged 65 and older. It also covers younger people with long-term disabilities and end-stage renal disease. Medicare was signed into law in 1965 under the Social Security Act and has provided fundamental health coverage to older adults for over 50 years.
Medicare consists of different parts, each covering certain services. Medicare Part A covers hospital and inpatient care. Medicare Part B covers physician services, outpatient care, preventive services, and medical equipment. Medicare Advantage Plans, or Part C, offer an alternative way to receive Medicare benefits through private insurers. And Medicare Part D provides prescription drug coverage.
Medicare Trust Fund
Trust Fund
Medicare has two main trust funds that help finance the program – the Hospital Insurance Trust Fund and the Supplementary Medical Insurance Trust Fund. So what are these trust funds?
A Medicare trust fund is essentially a pot of money, made up of dedicated revenue from payroll taxes, beneficiary premiums, and federal income taxes. The funds are set aside and invested in interest-earning Treasury securities to pay for Medicare benefits and administrative costs.
Trust Fund Solvency
By law, the Medicare trust funds cannot borrow money. Revenues going into a trust fund must be sufficient to cover that part’s expenses. If a trust fund is depleted, Medicare would be unable to fully pay providers and health plans. That is why monitoring the solvency of the Medicare trust funds is so important.
Medicare Parts
The two main Medicare trust funds finance different parts of the Medicare program:
Part A
The Hospital Insurance (HI) Trust Fund finances Medicare Part A, or hospital insurance. This trust fund pays for services like inpatient hospital stays, skilled nursing facility care, hospice, and some home health services.
Part B
The Supplementary Medical Insurance (SMI) Trust Fund finances Medicare Part B and Part D. Part B helps pay for physician services, outpatient hospital care, medical equipment like wheelchairs, and preventive services.
Medicare Financing
Medicare is funded through a combination of sources including payroll taxes, premiums, deductibles, and federal income taxes.
Medicare Spending
In 2022, Medicare spending is estimated to have reached $854 billion and is projected to almost double to $1.5 trillion by 2028. This rising spending is putting pressure on the Medicare trust funds.
Medicare Is Funded
Medicare Part A is primarily funded by payroll taxes through FICA and the Self-Employment Contributions Act. Employers and employees each pay 1.45% of earnings which go into the Hospital Insurance Trust Fund.
For Part B, about 25% of funding comes from beneficiary premiums. The remaining 75% is covered by federal income taxes and transfers from the general fund of the U.S. Treasury.
Part D prescription drug plans are funded through beneficiary premiums, federal subsidies, and transfers from the general fund.
Pay for Medicare
Beneficiaries also pay for portions of their Medicare out of pocket through deductibles, coinsurance, and copays. But the bulk of Medicare spending is financed through the payroll taxes, income taxes, government transfers, and premiums going into the Medicare trust funds.
Spending and Financing
Both Medicare spending and the number of beneficiaries are expanding rapidly as baby boomers age into Medicare eligibility. At the same time, the resources financing Medicare are more constrained. This imbalance is creating concern about the long-term viability of the Medicare trust funds.
Medicare Hospital Insurance Trust Fund
Financing for Medicare Part A comes primarily from the Medicare Hospital Insurance (HI) Trust Fund. Here is how this trust fund works:
Hospital Insurance
Medicare Hospital Insurance, or Part A, helps pay for inpatient hospital, skilled nursing, hospice, and certain home health services for millions of Americans. These benefits are crucial but also among the most costly that Medicare covers.
Hospital Insurance Trust Fund
The HI Trust Fund specifically receives income from payroll taxes, a small amount of beneficiary premiums, and interest earnings to fund Part A benefits. But Medicare hospital spending has exceeded this trust fund’s income in most years.
Part of Medicare
The HI Trust Fund is the largest of Medicare’s trust funds. But it is also facing insolvency most quickly, with depletion projected in 2028 if changes are not made. Since this finances vital hospital coverage for older adults, the looming shortfall is a major concern.
Medicare Advantage
You may be wondering how Medicare Advantage, or Part C, is funded since many beneficiaries get their Medicare benefits this way. Here is a look:
Insurance Trust
While Medicare Advantage Plans are an alternative to Original Medicare, they are still part of the Medicare program and financed largely through the SMI Trust Fund.
Medicare Part B
The SMI Trust Fund includes money allotted for Medicare Part B spending. Medicare pays the private insurers offering Medicare Advantage Plans a monthly lump sum for each enrolled beneficiary.
So while beneficiaries choose to receive benefits through a private Medicare Advantage Plan, the overall funding source is still Medicare via the SMI Trust Fund. The solvency of both trust funds is critical for financing all parts of Medicare.
In summary, Medicare relies on two main trust funds which are supported through dedicated payroll taxes, beneficiary premiums, and income taxes. Monitoring the adequacy of these trust funds is crucial to ensuring Medicare remains solvent and available to provide health coverage for older Americans. As the population ages, enhancing Medicare’s financing will grow even more important.
