Medicare open enrollment runs from October 15 to December 7, 2026, giving beneficiaries time to adjust their coverage before the 2027 Medicare changes take effect on January 1, 2027.
As of October 2026, people across the country can review their plan options for the coming year. This explainer from BoringMagazine.Co covers the confirmed dates, Part D rules, and price updates that take effect in 2027.
This article provides general information only, not financial, legal or medical advice. Coverage rules depend on individual plans, so readers should check the official source for their own situation, such as Medicare.gov or CMS.
What Changed for Part D and Prescription Drug Costs
Medicare Part D includes several updates for 2027. The Part D annual out-of-pocket cap rises to $2,400 in 2027, up from $2,100 in 2026. Once an enrollee spends $2,400 out of pocket on covered drugs during the calendar year, they pay nothing out of pocket for covered Part D medications for the rest of that year.
The standard Part D deductible is expected to rise from $615 to about $700. This figure is a forecast reported by analysts, not yet a final CMS number. Individual plans may set lower deductibles, but the standard benchmark deductible is expected to rise to about $700 before plans share drug expenses.
Monthly premiums may also shift. A temporary Part D premium subsidy, which offered about $16 a month off stand-alone plan premiums in 2026, ends at the end of 2026, so some premiums may rise. Without that relief, stand-alone drug plans may increase monthly charges.
From January 1, 2027, Medicare-negotiated prices take effect for 15 more drugs. They include Ozempic, Wegovy and Rybelsus, Trelegy Ellipta, Janumet and Janumet XR, Linzess, Tradjenta, Otezla, Breo Ellipta, Austedo, Xifaxan and Vraylar, and CMS publishes the full list. CMS estimates about $685 million in out-of-pocket savings for beneficiaries in 2027 from these prices.
Who It Affects
These updates affect all people enrolled in Medicare prescription drug coverage. Enrollees taking brand-name prescriptions will notice the biggest shifts.
People taking any of the 15 negotiated drugs may see lower out-of-pocket costs at the pharmacy counter starting January 1, 2027. Because CMS estimates about $685 million in out-of-pocket savings for beneficiaries in 2027 from these prices, patients who rely on these prescriptions may pay lower copayments or coinsurance.
People with high drug costs will face a higher ceiling. Because the Part D annual out-of-pocket cap rises to $2,400 in 2027, up from $2,100 in 2026, members who reach the cap will spend more money out of pocket before catastrophic coverage begins for the calendar year.
Beneficiaries in stand-alone drug plans may see higher monthly bills because the temporary Part D premium subsidy of about $16 a month ends at the end of 2026. Furthermore, because some plans may change benefits, copays or service areas, every beneficiary should verify their plan details each year.

What to Do Now
Because some plans may change benefits, copays or service areas, people should compare plans each year. Taking practical steps during open enrollment helps you find the right coverage before December 7, 2026.
First, write down all your current medications, exact dosages, and preferred pharmacies. Check whether your prescriptions include any of the 15 negotiated drugs.
Second, review the annual notice of change from your plan. Check whether your plan changes premiums, copays, or service areas for 2027. If your stand-alone plan raises premiums after the temporary $16 monthly subsidy ends, review alternative plans.
Third, compare plans on Medicare.gov. Enter your drugs to see total estimated out-of-pocket costs, accounting for the expected deductible rise to about $700 and the $2,400 cap. Submit plan changes before December 7, 2026, so coverage starts January 1, 2027.
Fourth, consult official resources if you need assistance. Contact CMS or review Medicare.gov for individual guidance. Readers exploring family options can also learn about ACA open enrollment for 2027 coverage or read more news explainers on federal programs.
