WASHINGTON, APRIL 18, 2026 —
Key Takeaways
- Medicare Part B premiums rose nearly 10% in 2026 to $202.90 per month — the largest single-year dollar increase in years — while the Part D prescription drug cap climbed slightly to $2,100, providing a ceiling on out-of-pocket drug costs that could save some seniors thousands annually.
- Nearly 9 million Medicare Part D enrollees will see out-of-pocket costs drop by an average of 50% on 10 specific brand-name medications this year, as the first round of Medicare drug price negotiations takes effect — drugs treating blood clots, diabetes, heart disease, and cancer are included.
- Nearly 3 million seniors were involuntarily dropped from their Medicare Advantage plans heading into 2026 as insurers exited unprofitable markets — the highest plan exit rate in the program’s history — leaving millions scrambling to find new coverage in a shrinking marketplace.
Medicare covers more than 67 million Americans. For most of them, it is the most important financial and healthcare decision they make in retirement — and the one they understand least. In 2026, the changes to Medicare are significant enough that doing nothing and assuming your coverage is the same as last year could cost you thousands of dollars in unnecessary out-of-pocket expenses, or leave you without coverage you thought you had.
This is the complete picture of what changed, who it affects, and exactly what you should be doing about it right now.
Part B Premiums Jumped Nearly 10% — Here’s the Real Cost
The standard monthly Medicare Part B premium — which covers doctor visits, outpatient services, and preventive care — rose from $185 to $202.90 in 2026, an increase of $17.90 per month. Annually, that’s $214.80 more per year than 2025 for every Medicare beneficiary on standard Part B. The annual Part B deductible rose from $257 to $283.
For the roughly 57 million Americans who have their Part B premium automatically deducted from their Social Security check, this increase reduced the net impact of the 2.8% COLA raise. The average SSDI beneficiary received a $44 monthly increase from the cost-of-living adjustment, but then lost $17.90 of that immediately to the Part B premium increase — leaving a net real-world gain of approximately $26 per month.
For higher-income Medicare beneficiaries, the situation is worse. Those earning above $103,000 individually or $206,000 jointly pay significantly higher premiums through the Income-Related Monthly Adjustment Amount — and those IRMAA thresholds affect millions of retirees with pension income, Social Security, and investment distributions combined.
The Part A inpatient hospital deductible — what you pay for the first 60 days of a hospital stay — rose to $1,676 per benefit period in 2026 from $1,632 in 2025. Daily coinsurance for hospital stays from day 61 through 90 rose to $434 per day. For seniors facing a serious hospitalization, these numbers represent real and significant costs that Medigap supplemental insurance is designed to cover.
The Drug Price Negotiations That Could Save You $1,500+ Per Year
The most consequential Medicare change of 2026 for seniors on expensive medications is the debut of the first federally negotiated drug prices under the 2022 Inflation Reduction Act. For the first time in history, the Department of Health and Human Services negotiated directly with pharmaceutical companies on the prices of 10 specific high-cost brand-name drugs. Those negotiated prices take effect January 1, 2026.
The 10 drugs span multiple serious conditions — including diabetes, blood clots, autoimmune disease, heart failure, and cancer. Nearly 9 million Medicare Part D enrollees use at least one of these medications. According to AARP research, out-of-pocket costs for these drugs will fall by approximately 50% on average compared to 2025. For seven of the ten drugs, average out-of-pocket costs will drop below $100 per month — a threshold only two of the ten drugs crossed in 2025.
| Medicare Drug Price Negotiation — 2026 Impact | |
|---|---|
| Number of drugs with negotiated prices | 10 |
| Enrollees who use these drugs | ~9 million |
| Average out-of-pocket cost reduction | ~50% |
| Drugs below $100/month out-of-pocket | 7 of 10 (was 2 of 10 in 2025) |
| Estimated total beneficiary savings | $1.5 billion |
| 2026 Part D annual out-of-pocket cap | $2,100 |
| Once you hit the cap | $0 for covered drugs rest of year |
If you take any of the 10 negotiated drugs — which include widely used blood thinners, diabetes medications, and heart failure treatments — your costs should have dropped significantly at the pharmacy counter starting January 1. If they did not, contact your plan directly to confirm the negotiated price is being applied correctly. All Medicare Advantage plans with drug coverage and all standalone Part D plans are required to include these drugs in their formularies at the negotiated price.
3 Million Seniors Lost Their Medicare Advantage Plans — Are You Among Them?
The most disruptive Medicare story of 2026 is not a policy change — it is a market collapse. Heading into the 2026 plan year, private insurers exited 10% of Medicare Advantage markets across the country, the highest plan exit rate in the program’s history. The result: nearly 3 million seniors who had been enrolled in Medicare Advantage plans found themselves without coverage at the start of 2026, forced to find new plans under intense time pressure.
The exits were driven by a math problem that had been building for years. After the COVID-19 pandemic, seniors flooded back into medical care, driving utilization far above insurers’ projections. Meanwhile, the Centers for Medicare and Medicaid Services slowed payment increases to insurers to close what analysts described as a persistent overpayment relative to traditional Medicare. The result was that dozens of counties across the country — particularly rural counties and markets dominated by smaller carriers — became unprofitable for private insurance companies.
The Medicare Advantage Open Enrollment Period, which ran from January 1 through March 31, gave displaced seniors one window to find new coverage. Seniors who missed that window are largely locked in — or out — until the Annual Enrollment Period begins October 15. If you were affected and did not find new coverage before March 31, contact Medicare directly to understand your remaining options, including whether a Special Enrollment Period applies to your situation.
For those still on Medicare Advantage, the marketplace has shrunk. The average number of available plans per county decreased for 2026. Some plans have changed their formularies, networks, or prior authorization rules. If you have not reviewed your Annual Notice of Change document — which your insurer was required to mail you before the plan year — read it immediately.
A New Prior Authorization Pilot That Could Delay Your Care
In a change that has flown largely under the radar, the Centers for Medicare and Medicaid Services launched a six-year prior authorization pilot in 2026 for certain Part B services in six states. Under this pilot, original Medicare enrollees in those states may need to obtain insurer approval before receiving certain outpatient procedures — including specific orthopedic procedures and certain wound care treatments.
Prior authorization is common in private insurance but has historically not applied to original Medicare, where doctors have generally been able to order covered services without pre-approval. The pilot tests whether adding prior authorization requirements reduces unnecessary utilization without harming patient outcomes.
Under the new rules, insurers must respond to urgent prior authorization requests within 72 hours and standard requests within 7 days — significantly faster than prior processes that could stretch for weeks. Emergencies and inpatient care are exempt.
If you are in original Medicare in one of the pilot states, ask your doctor before scheduling any outpatient procedure whether prior authorization is required and whether they have submitted the request. Failure to obtain prior authorization where required could result in claims denials.
What This Means For You
If you take brand-name medications covered by Part D, check your 2026 Explanation of Benefits statement to confirm your costs dropped. If you are on any of the 10 negotiated drugs and your costs stayed the same or rose, call your plan immediately — this may be a billing error.
If you were dropped from a Medicare Advantage plan and missed the January-March enrollment window, contact 1-800-MEDICARE to determine whether you qualify for a Special Enrollment Period based on plan termination. Seniors whose plans were terminated have guaranteed issue rights for Medigap supplemental insurance — meaning no carrier can deny you coverage for preexisting conditions.
If you are approaching Medicare eligibility, understand that 2026 is not the time to be passive. The landscape is more complex than it has been in years — with rising premiums, a shrinking Advantage marketplace, new drug savings, and new prior authorization rules all arriving simultaneously.
