CMS prepares final 2027 Medicare plan and premium release
Medicare beneficiaries should prepare to review their 2027 coverage soon, but federal officials have not yet published the final plan-by-plan premiums, drug lists and provider and pharmacy networks that will determine what many people pay next year.
The Centers for Medicare & Medicaid Services released preliminary technical Part D information on July 28, including a 2027 national average monthly bid amount of $296.05 and a base beneficiary premium of $41.33. CMS said the final Medicare Advantage and Part D landscape and final average premiums would be released in mid-to-late September after plan offerings are finalized.
CMS’s open-enrollment materials page, last modified September 3, still listed 2027 Medicare cost materials, Medicare.gov and Plan Finder updates, state-by-state landscape fact sheets and plan source files as coming soon. A separate CMS enrollment guide says information for next year’s plans will be available beginning in October.
What the preliminary figures mean
The $296.05 national average monthly bid amount is not a price that every beneficiary will pay. CMS defines it as an enrollment-weighted average of applicable Part D plan bids for basic benefits. The figure is used in calculating the government subsidy paid to plans.
The $41.33 base beneficiary premium is also not a universal monthly bill. CMS describes it as the starting point for calculating a plan-specific basic Part D premium under a statutory formula.
The temporary Part D demonstration is ending
CMS said the voluntary Part D Premium Stabilization Demonstration will end after calendar year 2026. The agency said Part D plans will return to traditional market conditions in 2027 after plan sponsors gained experience with the redesigned benefit.
The decision does not establish a universal premium increase. What an individual pays will depend on the plan available in that person’s ZIP code, the plan’s premium and benefits, prescriptions, pharmacy choices and other factors.
Associated Press reporting said the end of the temporary program could make plan-by-plan comparisons more important, while the effect on individual premiums remained uncertain until final information is released.
Mark the enrollment dates
Medicare’s annual open-enrollment period runs from October 15 through December 7, 2026. During that window, people with Medicare can change Medicare Advantage or prescription drug coverage for the following year.
Beneficiaries do not have to change plans. CMS says people should review the Annual Notice of Change and Evidence of Coverage materials sent by their current plans. If the plan is still offered and continues to meet their needs, no change may be necessary.
What to compare before choosing
For Part D coverage, check the monthly premium, deductible, covered prescriptions, drug tiers, prior-authorization and step-therapy rules, pharmacy network and payment arrangements. Do not assume that a plan advertised with a $0 premium will remain $0 in 2027.
KFF Health News has documented cases in which beneficiaries lost drug coverage after small or unexpected premium changes created payment and enrollment problems. The practical lesson is to confirm both the amount due and how the plan will collect it.
Medicare Advantage enrollees should verify doctors, hospitals and specialists, as well as referrals, prior-authorization rules, supplemental benefits and the plan’s maximum out-of-pocket limit.
Compare total expected annual costs rather than focusing only on the monthly premium. Prescription needs, medical visits, deductibles, copayments, coinsurance and network restrictions can change the overall cost of a plan.
Once final 2027 information is available, beneficiaries can compare plans through Medicare.gov or by calling 1-800-MEDICARE. Free counseling is also available through the State Health Insurance Assistance Program. The key deadline for changes taking effect in 2027 is December 7, 2026.
