— A look at the biggest changes
October 15, 2026 • 3 min read
Open enrollment for Medicare plans begins Thursday and enrollees will face a slew of changes that go into effect in 2027.
During the enrollment period, which ends Dec. 7, people will have the opportunity to choose between traditional Medicare and privately run Medicare Advantage plans in their area, as well as prescription drug plans. Those changes go into effect on Jan. 1.
Open enrollment also comes as inflation adds pressure on seniors whose healthcare costs have risen and as midterm elections are weeks away. Voters have consistently said cost-of-living is a major concern headed into the elections.
The Medicare enrollment period also comes as the Social Security Administration announced Wednesdayopens in a new tab or window that the annual cost-of-living adjustment for older adults and people with disabilities will go up by 3.6% beginning in 2027, which translates to $75 extra per month for the nearly 72 million people who receive monthly Social Security benefits and about 7.3 million beneficiaries who get Supplemental Security Income.
New changes to Medicare coming in 2027 include higher Part D out-of-pocket caps, the end of temporary federal Part D premium subsidies, and new drug price negotiations.
Here are a few of the biggest changes:
Medicare Part D
The cap on annual out-of-pocket expenses for Medicare Part D drugs will increase to $2,400, up from $2,100 in 2026, and the standard deductible will increase from $615 to $700.
The temporary Part D premium subsidy will also end early.
The Trump administration concludes at year's end a temporary Medicare Part D subsidyopens in a new tab or window program that has helped offset premiums.
It was initially implemented by former President Joe Biden's administration in 2024 to lower patients' Medicare Part D prescription drug costs in response to effects of the 2022 Inflation Reduction Act.
The Centers for Medicare & Medicaid Services (CMS) has projected only modest price increases for most people. CMS did not respond to an Associated Press request for comment.
Drug Price Negotiations
New Medicare-negotiated prices, part of a Biden-era lawopens in a new tab or window that allows the haggling for Medicare, will go into effect for 15 drugs, including weight-loss and diabetes medication semaglutide (Ozempic, Rybelsus, Wegovy).
Additionally, fluticasone furoate, umeclidinium, and vilanterol (Trelegy Ellipta); enzalutamide (Xtandi); pomalidomide (Pomalyst); palbociclib (Ibrance); nintedanib (Ofev); linaclotide (Linzess); acalabrutinib (Calquence); deutetrabenazine (Austedo, Austedo XR); budesonide, glycopyrrolate, and formoterol fumarate (Breo Ellipta); linagliptin (Tradjenta); rifaximin (Xifaxan); cariprazine (Vraylar); sitagliptin and metformin (Janumet, Janumet XR); and apremilast (Otezla) will be covered by Medicare as of Jan. 1.
CMS expects the changeopens in a new tab or window to lower prescription drug coverage for people enrolled in Medicare by $685 million in 2027.
AARP's Executive Vice President and Chief Advocacy Officer Nancy LeaMond said in a statement that "higher healthcare costs are making it harder for older Americans to afford the care they need."
"It's more important than ever to shop around, compare your options, and choose the coverage that's best for you," she said.
Other Trump Administration Promises
Along with the changes, President Donald Trumpopens in a new tab or window in recent weeks made a series of promises to Medicare enrollees and retirees.
Last week, Trump said his administration will make one-time payments of $90 per personopens in a new tab or window in October to help more than 20 million Medicare enrollees -- or less than one-third of enrollees -- pay for their Part B premiums. It will cost about $2 billion.
Not eligible are roughly 35 million Medicare Advantage enrollees, millions of other people with disabilities, and low-income Medicare recipients.
According to the CMS website, eligible beneficiaries will receive one $90 rebate this month, with most getting a direct deposit. Others will receive a paper check from the Treasury Department later in October.
Trump also announced recently that roughly 1 million people would get rebate checks of $500opens in a new tab or window for Affordable Care Act premiums.
