Every year, the Medicare Trustees — a group of six officials including the Secretaries of Treasury, Labor, and Health and Human Services — release a detailed financial report on the health of the Medicare program. The 2026 report delivers a message that every beneficiary should understand: Medicare spending is growing faster than the program's income, and the timeline for a potential funding shortfall is getting closer. This is not a reason to panic, but it is a reason to pay close attention to how these trends may affect your coverage choices, your costs, and the political decisions that will shape Medicare for the next decade.
The most headline-grabbing finding in the 2026 Trustees Report involves the Hospital Insurance trust fund, which is the pool of money that pays for Medicare Part A — your hospital stays, skilled nursing facility care, home health services, and hospice. The Trustees project that this trust fund will be depleted by approximately 2033. That does not mean Medicare disappears. What it means, under current law, is that incoming payroll tax revenue would only cover about 89 cents of every dollar owed to hospitals and other Part A providers. Congress has historically acted before depletion dates arrive, but there is no guarantee of what form that action will take — whether it means benefit cuts, premium increases, tax hikes, or some combination. Beneficiaries who rely heavily on hospital or skilled nursing facility care should be aware that this funding pressure exists.
Total Medicare spending in 2025 is estimated at approximately $1.1 trillion, according to projections consistent with CMS.gov data and Trustees Report modeling. That figure is expected to grow substantially over the next decade as the last of the Baby Boomer generation ages into Medicare eligibility. By 2034, Medicare spending is projected to represent roughly 4.3 percent of the entire U.S. gross domestic product, up from about 3.1 percent a decade ago. These are not abstract numbers — they represent the financial pressure that drives decisions about premiums, plan benefits, and provider reimbursement rates that directly affect what you pay and what care you can access.
Data Snapshot: According to CMS.gov data, Medicare Advantage enrollment reached approximately 33.8 million beneficiaries in 2025, representing more than 54 percent of all Medicare-eligible individuals. The number of Medicare Advantage plans available nationally in 2025 was 4,009 — a slight contraction from the peak of recent years as insurers pulled back from some markets due to tightening reimbursement rates. The average Medicare Advantage plan premium in 2025 was approximately $17 per month, though many plans continue to offer $0 premium options in competitive markets. These enrollment and plan availability figures matter because Medicare Advantage now accounts for a growing share of total Medicare expenditures, and how CMS reimburses these plans has become a central driver of the program's overall financial trajectory.
One of the most important dynamics the 2026 Trustees Report highlights is the relationship between Medicare Advantage growth and overall program costs. For years, Medicare Advantage was promoted as a cost-saving alternative to traditional Medicare, with the theory that private insurers could deliver care more efficiently. The reality has proven more complicated. Multiple analyses, including work from KFF and the Medicare Payment Advisory Commission (MedPAC), have found that the federal government pays Medicare Advantage plans more per enrollee than it would cost to cover those same people under traditional Medicare — a gap that has been estimated at $83 billion in excess payments in 2023 alone. CMS has been gradually tightening the payment benchmarks and risk adjustment methodology used to calculate what MA plans receive, which is one reason some insurers reduced benefits or exited markets in 2025 and 2026.
For beneficiaries currently enrolled in a Medicare Advantage plan, this reimbursement squeeze has real consequences. When insurers receive less money from CMS, they typically respond by reducing supplemental benefits — things like dental, vision, hearing, and over-the-counter allowances that are not covered by traditional Medicare. In 2025 and heading into 2026, many plans reduced or eliminated these extras, and some plans raised their out-of-pocket maximums. The statutory out-of-pocket maximum for Medicare Advantage in 2025 is $9,350 for in-network services and $14,000 for combined in- and out-of-network costs. If your plan is near those limits, you are carrying significant financial exposure for a serious illness or hospitalization. Reviewing your plan's Evidence of Coverage document — available from your insurer or at Medicare.gov — is the most direct way to understand your actual exposure.
Traditional Medicare spending trends are equally important to understand. The standard Medicare Part B premium in 2025 is $185.00 per month for most beneficiaries, up from $174.70 in 2024. Higher-income beneficiaries pay more through the Income-Related Monthly Adjustment Amount, or IRMAA. If your individual income exceeded $106,000 in 2023 (the income year used for 2025 IRMAA calculations), you are paying a surcharge on top of the standard premium — ranging from an additional $74.00 to $443.90 per month depending on your income bracket. The Part B deductible in 2025 is $257. The Part A inpatient hospital deductible is $1,676 per benefit period — and critically, there is no cap on how many benefit periods you can have in a year, which is why many beneficiaries in traditional Medicare carry a Medigap supplemental policy.
Medigap, also called Medicare Supplement insurance, is one of the most effective tools for managing out-of-pocket risk in traditional Medicare. Plan G is currently the most comprehensive option available to new Medicare enrollees (Plan F was closed to new enrollees as of January 1, 2020). Plan G covers the Part A deductible, skilled nursing facility coinsurance, Part B excess charges, and foreign travel emergency care — leaving you responsible only for the Part B deductible. Average monthly premiums for Medigap Plan G vary significantly by age, gender, tobacco use, and state, but typically range from roughly $100 to $250 per month for a 65-year-old, with premiums rising as you age. If you are in one of the 13 birthday rule states — California, Idaho, Illinois, Kentucky, Louisiana, Maine, Maryland, Missouri, Nevada, New Jersey, New York, Oklahoma, or Oregon — you have a 30-day window each year around your birthday to switch Medigap plans without medical underwriting, which is a meaningful consumer protection worth using if you find a better rate.
The prescription drug spending trajectory is another major driver of the numbers in the 2026 Trustees Report. Medicare Part D spending has been reshaped by the Inflation Reduction Act, which took effect in stages beginning in 2023 and reached a significant milestone in 2025 with the implementation of a $2,000 annual out-of-pocket cap on Part D drug costs. This cap is genuinely valuable for beneficiaries who take expensive specialty medications — people who previously faced unlimited exposure in the catastrophic phase of Part D coverage. However, the cost of funding this cap is being distributed across the system through higher plan premiums and changes to how manufacturers and pharmacies are paid. The average Part D standalone plan premium in 2025 increased notably compared to prior years, and beneficiaries should compare their current plan against alternatives during the Annual Enrollment Period, which runs October 15 through December 7 each year.
The Annual Enrollment Period — AEP — is the single most important window for most Medicare beneficiaries to act on the information in reports like this one. From October 15 through December 7, you can switch from traditional Medicare to Medicare Advantage, switch between Medicare Advantage plans, return to traditional Medicare from Medicare Advantage, and change your Part D drug plan. Changes take effect January 1. If you miss AEP and realize in early spring that your plan is not working, the Medicare Advantage Open Enrollment Period runs January 1 through March 31 — but it only allows you to switch from one MA plan to another or return to traditional Medicare; you cannot use it to enroll in a new Part D plan if you are in traditional Medicare. Special Enrollment Periods exist for qualifying life events such as moving out of your plan's service area, losing employer coverage, or qualifying for Extra Help with drug costs.
The broader message of the 2026 Trustees Report for individual beneficiaries is this: Medicare is not going away, but it is under financial pressure that will continue to produce changes in premiums, benefits, and plan availability year after year. The best defense is an active approach to your coverage. Compare plans every fall during AEP using the Medicare Plan Finder tool at Medicare.gov, which allows you to enter your specific medications and preferred pharmacies to get an accurate cost comparison. If you are in traditional Medicare, review your Medigap coverage annually and check whether your state's birthday rule gives you a chance to find a lower premium. If you are in Medicare Advantage, read your Annual Notice of Change letter — which plans are required to mail by September 30 each year — to understand exactly what is changing in your plan before AEP begins. The financial trends documented in the Trustees Report are real, but informed beneficiaries have more tools than ever to navigate them effectively.
