Medicare's prescription drug spending limit is set to increase by $300 in 2027, even as negotiated prices expand to more medications. Premiums are also shifting, although the amount you pay will depend on your specific plan.
You do not need to track every Medicare announcement to make an informed coverage decision. What matters is knowing which updates could affect your prescriptions, monthly costs, and access to care. Looking at these changes now gives you time to compare plans before open enrollment. Here's a closer look at what is changing.
Negotiated prices will cover 15 more drugs
Beginning January 1, 2027, Medicare-negotiated prices will apply to 15 additional drugs, bringing the total to 25. The expanded list includes treatments for diabetes, cancer, asthma, and other chronic conditions.
CMS estimates combined out-of-pocket savings of $685 million in 2027. How much of that benefit reaches you will depend on your prescriptions and your plan's cost-sharing rules.
The Part D out-of-pocket cap increases to $2,400
The annual out-of-pocket limit for covered Part D prescriptions will rise from $2,100 in 2026 to $2,400 in 2027, according to CMS's finalized benefit amounts.
For someone with costly prescriptions, that means up to $300 more in spending before reaching the cap. The $2,400 limit applies only to covered Part D drugs. It does not include monthly premiums, and it generally does not count spending on medications outside your plan's coverage.
The standard drug deductible climbs to $700
The standard Part D deductible will increase from $615 to $700 in 2027. Some plans may charge less or waive the deductible for certain drugs, so $700 is not necessarily what you will pay.
Still, this figure matters if you usually pay most of your prescription costs early in the year. The deductible counts toward the Part D out-of-pocket limit; it is not an additional $700 on top of the $2,400 cap.
Temporary Part D premium support is ending
CMS has confirmed that the Part D Premium Stabilization Demonstration will end after 2026. This temporary program provided extra support to participating standalone prescription drug plans to help soften premium changes.
Some plans may raise premiums once that support disappears. Review the 2027 premium listed in your Annual Notice of Change, even if you have been satisfied with your coverage.
Average Medicare Advantage premiums are expected to decline
CMS projects an average Medicare Advantage premium of $12 per month in 2027, down from $14.37 in 2026.
That average is weighted toward plans with more members, so it does not necessarily reflect what you will pay. It also does not represent your full Medicare cost: You will generally still owe the Part B premium. Compare copays and benefits along with the monthly premium.
Standalone drug plan premiums are expected to inch higher
For standalone Part D plans, CMS projects an average monthly premium of $36 in 2027, compared with $35.09 in 2026.
Your increase could be larger than the average. And any savings on premiums can be erased quickly if a medication you use every month becomes more expensive. Compare the estimated yearly cost of premiums and prescriptions together, using the pharmacies you actually use.
Medicare Advantage will have slightly fewer plans nationwide
CMS expects about 5,532 Medicare Advantage plans nationwide in 2027, down from 5,553 in 2026. About 97% of beneficiaries will still have access to at least 10 options.
Those national numbers do not show what is available in your county. Check your ZIP code in Medicare Plan Finder, especially if your insurer has told you that your current plan is ending.
Star ratings now include more medication-safety measures
The 2027 Star Ratings, released for enrollment comparisons, add measures that review opioid-and-benzodiazepine combinations and the use of multiple anticholinergic medications in older adults.
If you take several prescriptions, those safety-related measures may deserve a closer look. Review the individual scores as well as the overall star rating when comparing plans.
Plans must explain who qualifies for certain extra benefits
Under the 2027 final rule, Medicare Advantage plans must publicly post their own eligibility criteria for special supplemental benefits for chronically ill members.
That matters when an ad promises help with groceries or other everyday expenses. Enrollment alone does not always qualify you for those benefits. Before choosing a plan for a grocery allowance, ask whether you qualify and how much you would actually receive.
Benefit cards will come with clearer spending rules
CMS also finalized requirements for supplemental-benefit debit cards, including real-time checks to confirm that purchases qualify for plan coverage and limits tying the cards to the specific plan year.
Before counting on a benefit card in your budget, check what it covers, where it can be used, and when the funds expire. The advertised allowance may be less helpful if it excludes the stores or items you normally buy.
The bottom line
Medicare's 2027 changes may lower some prescription costs while also leaving you with a higher deductible or premium. If you rely mostly on Social Security, compare your total annual costs before renewing. A lower monthly premium may not offset higher medication charges if you refill prescriptions every month.
If you are switching Medicare Advantage plans, confirm with both the insurer and your doctors' offices that your doctors are in the new plan's network. Be sure to use the exact plan name, since different plans from the same insurer may have different networks.
