Medicare Has Eight Years. Nobody in Washington Is Telling You That.

The trust fund runs out in 2033. Congress just made the math worse.

Every week I perform joint replacements on Medicare patients. Total knees. Total hips. Patients who have spent their entire working lives paying into a program that promised to cover their medical care when they needed it most.

I think about those patients when I read the Medicare Trustees’ 2025 report, released last month, which moved the Medicare Hospital Insurance trust fund insolvency date from 2036 to 2033. Three years earlier than last year’s projection. Eight years from now.

When that trust fund runs out, payments to hospitals and physicians like me get cut by 11% automatically, unless Congress acts. The patients in my waiting room, who paid into this system for 40 years, will either lose access to providers who can no longer afford to see them at 11% below already compressed reimbursement rates, or watch the program they funded become something unrecognizable.

And as of today, there is no credible plan to prevent that.

The Clock Is Running. The Math Is Getting Worse.

The Medicare Trustees estimate the Medicare Hospital Insurance trust fund will be insolvent by 2033, at which point Medicare Part A benefit spending will be slashed by 11%. This is not a distant projection. The youngest baby boomers are currently 61 years old. They will be 69 when the trust fund runs dry. The wave that was always coming is fully here.

The program covered approximately 67.6 million people at the end of 2024. Total enrollment is projected to increase substantially by 2030, driven by the continued aging of the baby boomer generation. This demographic shift is changing the ratio of workers paying into the system compared to beneficiaries drawing benefits.

The structure of the problem is straightforward. Medicare Part A is funded by a 2.9% payroll tax. The working-age population paying that tax is shrinking relative to the retired population drawing benefits. The cost per beneficiary is rising as that population ages into higher-need care years. The reserve is being drawn down. By 2033, the math closes.

Part B premiums are projected to nearly double between 2024 and 2034, from $2,100 per year to more than $4,000 per year. Seven million Medicare beneficiaries already spend more than 10% of their annual income on Part B premiums alone. That burden doubles in a decade under current trajectory, before accounting for any trust fund crisis intervention.

The people most exposed to this are not abstractions. They are my patients. Working-class Americans who did everything the system asked of them, paid their payroll taxes for decades, and are about to discover that the contract they believed in is financially unsustainable.

Then Congress Made It Worse

Into this fiscal environment, Congress passed and the President signed the One Big Beautiful Bill Act on July 4, 2025.

The nonpartisan Congressional Budget Office estimated that the OBBBA will reduce federal Medicaid spending by more than $900 billion over a decade. Specifically, CBO estimates the health coverage provisions would reduce federal outlays by $907.5 billion over ten years, with 4.8 million people losing health insurance coverage by FY2034.

I want to be precise about what this means in practice, because the political debate around this legislation has generated significant confusion.

The OBBBA does not technically reduce spending below current levels in nominal dollar terms. Healthcare costs grow every year. What the cuts do is reduce that growth significantly below what it would otherwise be. The patients who lose Medicaid coverage as work requirements take effect, eligibility redeterminations accelerate, and provider tax restrictions constrain state funding, do not disappear. They become uninsured. And when they need care, many of them will arrive in emergency departments, or delay care until conditions become acute, or lean harder on a Medicare system that is already fiscally strained.

More than 300 rural hospitals are currently at immediate risk of closure, especially now that the OBBBA is projected to cut Medicaid spending by over $1 trillion. The average operating margin for rural hospitals was 3.1% in 2023. Forty-four percent were already operating with negative margins. A $900 billion reduction in federal Medicaid support does not land evenly. It lands on the institutions with the least cushion.

When rural hospitals close, the patients they served do not stop getting sick. They drive farther, wait longer, and arrive in worse condition when they finally reach care. The savings Congress booked on a spreadsheet will be partially recouped, with interest, in emergency care costs, worse surgical outcomes, and longer recovery trajectories for patients who should have been treated earlier.

I operate on the downstream consequences of delayed and foregone care every week. The math the OBBBA uses is not the math that shows up in my OR.

The Conversation Nobody Is Having

Here is what is missing from the public debate about Medicare solvency, and I want to say it directly because I have standing to say it.

The Medicare program as currently structured cannot deliver on its promise indefinitely without either more revenue, lower costs, or reduced benefits. Those are the only options. Everything else is accounting.

More revenue means higher payroll taxes, broader tax bases, or both. Lower costs means reforming what Medicare pays for and how much, including painful conversations about end-of-life care, technology adoption, and the administrative infrastructure that consumes roughly $680 per beneficiary more in the U.S. than in comparable countries, per KFF analysis. Reduced benefits means patients get less than they were promised.

No politician running for office wants to say any of those things plainly. The result is a policy environment where the Trustees issue annual warnings, the insolvency date moves closer, and Congress oscillates between cutting the program’s funding (OBBBA) and expanding its obligations (proposed GLP-1 coverage for Medicare patients, projected at $27 billion annually within a decade).

Both moves, the cuts and the expansions, are happening simultaneously. The program is being asked to do more while the financial foundation supporting it is being actively reduced.

The GLP-1 coverage expansion deserves specific attention here. I have written about the clinical complexity of these drugs, including the muscle loss data that the press releases omit. What I have not said publicly is this: adding a $27 billion annual obligation to a program eight years from insolvency, without a corresponding revenue mechanism, is not healthcare policy. It is political positioning.

The patients who would benefit from GLP-1 coverage under Medicare are real. The cardiovascular outcomes data is real. I am not dismissing either. What I am saying is that a financially honest conversation about GLP-1 Medicare coverage requires simultaneously answering the question of how a program eight years from insolvency funds a new $27 billion per year commitment.

Nobody is answering that question. Not in the coverage expansion proposals. Not in the reconciliation bill. Not in the campaign materials of anyone currently in office.

What the Surgeon in the Room Understands

I perform joint replacements on Medicare patients every week. I know what the reimbursement looks like. I know what an 11% cut does to the economic model of a surgical practice. I know how many orthopedic surgeons, across the country, are already making access decisions based on Medicare payment rates.

An 11% automatic cut at trust fund insolvency does not arrive with a warning bell and a transition period. It arrives on the day the reserve hits zero, applied immediately to every Medicare claim submitted. The practices and hospitals operating on thin margins around Medicare reimbursement do not absorb that cut gracefully. They reduce Medicare patient volume. They close. Or they exit certain service lines and certain geographies.

The patients most exposed are not wealthy. More than one-third of Medicare beneficiaries reported delaying or going without care in 2023 because of cost. Those are people already at the margin of access. An 11% provider payment cut does not affect them at the margin. It eliminates their access.

At Indiana Orthopedic Institute, the ASC model and the operational structure we have built provide more insulation against Medicare payment volatility than a hospital-employed practice or a purely Medicare-dependent facility. That is a design advantage I built deliberately, because I have watched the trajectory of this program for my entire career and I do not believe the political class will act before the crisis rather than after it.

I hope I am wrong. The data says I am not.

What Honest Leadership Would Require

An honest conversation about Medicare would acknowledge three things simultaneously.

First, the program’s value is real and the commitment to beneficiaries is legitimate. Medicare is the primary healthcare coverage for 67 million Americans who paid for it. Honoring that commitment is a genuine obligation, not a political talking point.

Second, the fiscal trajectory is unsustainable without structural change. The 2025 Trustees report moved the insolvency date three years earlier in a single year. That is not a rounding error. That is a program accelerating toward a cliff.

Third, the cuts already enacted through OBBBA do not solve the solvency problem. They reduce Medicaid, which has a separate funding mechanism. The Medicare Hospital Insurance trust fund is funded by payroll taxes. Cutting Medicaid by $900 billion does not extend Medicare solvency by a single day.

The politicians celebrating the OBBBA as fiscal responsibility and the politicians proposing GLP-1 Medicare expansion as healthcare progress are, in different ways, performing for different audiences. Neither is having the conversation that the 2025 Trustees report demands.

The clock is at eight years. The math is getting worse. And the people who will feel it first are the ones who can least afford to.
