Key Insights

  • The Medicare Hospital Insurance (HI) trust fund may run out by 2032, but this is not the program’s biggest challenge.
  • The real issue is that Medicare operates in the most expensive health care system in the developed world, pushing costs ever higher.
  • Medicare Advantage, now covering nearly half of beneficiaries, costs about 20% more per person than traditional Medicare, adding to the financial strain.

When news breaks about Medicare, headlines often zero in on the date when the Hospital Insurance (HI) trust fund will be “exhausted.” The latest projections show that depletion could happen as soon as 2032, thanks in part to new tax changes. But while that sounds alarming, a report by the Center for Retirement Research at Boston University found the reality is less dire: even after the trust fund runs out, incoming payroll taxes will still cover nearly 90 percent of Part A’s expenses.

The real story isn’t that Medicare is running out of money. It’s that the program is very expensive—and getting more so.

Medicare is the largest public health program in the U.S., covering nearly all Americans over 65 as well as people with certain disabilities. It makes up more than one-fifth of all national health care spending and about 13% of the federal budget.

But unlike Social Security, where costs rise mainly because of an aging population, Medicare’s cost growth is being driven by something else: the high price of U.S. health care. Americans pay more for doctor visits, hospital stays, drugs, and administrative overhead than people in almost any other developed country. On average, U.S. health care costs are double those of peer nations in the Organisation for Economic Co-operation and Development (OECD).

This expensive environment means that Medicare, even though it is not unusually generous compared to private insurance, inevitably comes with a big price tag.

Medicare Advantage: A growing cost shift

One of the most striking trends is the rapid growth of Medicare Advantage (Part C), where beneficiaries get coverage through private insurers instead of traditional Medicare. Almost half of enrollees are now in Medicare Advantage plans, drawn by perks like dental and vision coverage, caps on out-of-pocket costs, and sometimes even zero premiums.

But these plans are costing the government more. In 2025, Medicare will pay about 20% more per beneficiary in Medicare Advantage than in traditional Medicare. Overpayments come from several sources:

  • Coding practices that make enrollees look sicker on paper than they really are.
  • Favorable selection, where healthier seniors gravitate to Medicare Advantage.
  • Quality bonuses that raise payments to private insurers.

This shift is inflating Medicare’s bill at a time when every dollar counts.

Looking ahead

The Medicare Trustees warn that if current-law limits on reimbursements to doctors and hospitals prove unsustainable, costs could end up even higher than projected. Hospitals already receive just 55 percent of what private insurers pay for similar services, and physicians get about 64 percent. If those payments are cut further, access to care for seniors could be threatened.

The bottom line: Medicare isn’t about to collapse, but it is becoming increasingly expensive – for taxpayers, for seniors, and for the health care system overall. Addressing the high costs of Medicare Advantage and tackling America’s sky-high health care prices may be the most important steps to keeping Medicare strong for the long run.
