What Is the Hospital Insurance Trust Fund?

The Federal Hospital Insurance Trust Fund is also known as Part A of Medicare, the health insurance program for people aged 65 and older in the United States. The program is financed through payroll taxes derived from current workers and employers as well as taxes on Social Security benefits. This trust fund is overseen by a board of trustees that report yearly to Congress regarding its financial status. Due to changes in legislation and demographics in the United States, the fund is projected to be depleted in 2026.

Understanding the Hospital Insurance Trust Fund

The Federal Hospital Insurance Trust Fund is managed by the U.S. government and pays for specific health care services for Medicare recipients, including hospital stays, hospices, and skilled nursing facilities. It is not an actual fund, with money coming in or going out, but rather an accounting mechanism to keep track of government securities that underpin the program.

Key Takeaways

  • The Federal Hospital Insurance Trust Fund is Part A of Medicare and covers hospital stays, hospices, and skilled nursing facilities.
  • The trust is not an actual fund, but rather an accounting mechanism for the government securities that underlie the program.
  • The hospital insurance trust is designed to be something that every worker pays into, then benefits from at retirement.
  • Given changing demographics and regulations, the trust fund is expected to be depleted by 2026 and, from that point forward, retirees will no longer receive full benefits from the program.

Medicare is a government-funded health insurance program for those 65 and older, disabled people, and people with a specific set of health conditions specified by the government. The other parts of Medicare—Parts B, C, and D—pay for health care services not covered by the hospital insurance trust fund (doctor visits, lab tests, and prescription drugs) and are funded through premium payments from beneficiaries.

The hospital insurance trust is funded by revenue from Social Security benefits and payroll taxes from all workers in the United States, not just from beneficiaries. The program is intended to be something all workers pay into and then receive benefits from when they reach normal retirement age or become unable to work anymore due to a disability. 

Disadvantages of the Hospital Insurance Trust Fund

If the hospital trust has a positive balance, payments from the fund can be made. But if the fund runs dry, millions of beneficiaries might lose insurance coverage with no mechanism to regain it. Analysts are concerned that the U.S. economy will not support the hospital trust within Medicare in the future because of changes in population demographics.

Indeed, the population of the United States is aging, as the birthrate goes down and as people live longer. This means that the number of younger workers to be taxed to support the trust fund is decreasing as the number of beneficiaries of the program is increasing.

The Social Security and Medicare Boards of Trustees released an annual financial review of Medicare programs on April 22, 2019. In the report, it was projected that the Federal Hospital Insurance Trust Fund can continue to pay full benefits until 2026 before it is depleted. After that, the share of scheduled benefits will drop to 89% (of full benefits) and then decline slowly to 77% through 2046, before rising gradually to 83% through 2093. The estimates are based on a number of factors, including utilization rates of skilled nursing facilities, overall levels of worker productivity, and recent trends in healthcare costs relative to individual incomes.
