Introduction
The latest Medicare rates 2027 announcement is giving beneficiaries a mixed picture ahead of open enrollment. The Centers for Medicare & Medicaid Services says the average monthly premium across Medicare Advantage plans is projected to fall from $14.37 in 2026 to $12 in 2027, while the average premium for stand-alone Part D prescription drug plans is expected to increase from $35.09 to $36.
That distinction matters because Medicare Advantage and stand-alone Part D plans work differently, and a lower average premium does not necessarily mean every beneficiary will pay less overall.
The new figures arrive just weeks before Medicare’s annual Open Enrollment period, which runs from October 15 through December 7, 2026, for coverage taking effect January 1, 2027.
Background and Context
The CMS announcement covers Medicare Advantage, commonly known as Medicare Part C, and Medicare Part D prescription drug coverage.
Medicare Advantage plans are offered by private insurers and generally combine Medicare hospital and medical coverage with additional benefits and, in many cases, prescription drug coverage.
Stand-alone Part D plans provide prescription drug coverage for people who receive their health coverage through Original Medicare.
CMS released the final 2027 premium projections on September 28, giving consumers a clearer picture of the private-plan market before enrollment begins.
The agency projects that the weighted average monthly premium across Medicare Advantage plans will fall 16.5%, from $14.37 in 2026 to $12 in 2027. For Medicare Advantage plans that include prescription drug coverage, the average monthly Part D premium after Medicare Advantage rebates is projected to fall from $11.32 to $7.
The stand-alone Part D picture is different. CMS projects an average monthly premium of $36 in 2027, compared with $35.09 in 2026.
Latest Update or News Breakdown
The headline numbers are straightforward:
- Medicare Advantage: $12 average monthly premium in 2027, down from $14.37.
- Stand-alone Part D: $36 average monthly premium, up from $35.09.
- Medicare Advantage plans with drug coverage: $7 average monthly Part D premium after MA rebates, down from $11.32.
- MA plan availability: About 5,532 plans are projected nationally in 2027, compared with 5,553 in 2026.
- MA access: More than 99% of Medicare beneficiaries are expected to have access to at least one Medicare Advantage plan, with 97% having access to 10 or more options.
The figures were also highlighted by USA TODAY, which reported that insurers must notify Medicare Advantage and Part D enrollees by September 30 about changes involving premiums, prescription drug coverage and provider networks.

The enrollment outlook is another important part of the story. CMS estimates Medicare Advantage enrollment at roughly 34 million people in 2027, or about 47.4% of people enrolled in Medicare. CMS also says historical enrollment projections have tended to underestimate actual enrollment.
That estimate is disputed within the industry. Modern Healthcare reports that Medicare Advantage insurers told CMS they expect enrollment to decline in 2027, while CMS expects enrollment to be higher than the plans’ projections.

Fierce Healthcare similarly reported the projected 16% decline in average Medicare Advantage premiums and the much smaller increase expected for stand-alone Part D.

Expert Insights or Analysis
The most important takeaway is that premium averages are not the same thing as total healthcare costs.
A plan with a lower monthly premium can still have higher deductibles, copayments, coinsurance or out-of-pocket exposure. Prescription formularies and provider networks can also change from one year to the next.
USA TODAY’s reporting noted that some Part D plans could attempt to manage costs by changing the drugs included on their formularies. KFF’s Juliette Cubanski also pointed to the possibility that insurers could adjust other elements of coverage even when headline premiums remain low.
CMS says 88% of non-low-income beneficiaries will have access to a basic Part D plan costing $10.30 or less per month, while 93% will have access to an enhanced Part D plan costing less than $6 per month. These figures describe plan availability, not what every beneficiary will pay or which plan will best fit an individual’s prescriptions.
There is also an important policy change behind the Part D numbers. CMS announced in July that the voluntary Part D Premium Stabilization Demonstration would end after 2026. The agency said the 2027 bids indicate insurers have more experience with the redesigned Part D benefit and that the program can return to traditional market conditions.
Broader Implications
For consumers, the 2027 Medicare rates story is less about finding the lowest advertised premium and more about checking the entire plan.
Before changing coverage, beneficiaries should compare:
- Monthly premiums.
- Prescription drug formularies.
- Drug copayments and coinsurance.
- Deductibles.
- Provider and hospital networks.
- Maximum out-of-pocket limits.
- Dental, vision and hearing benefits.
- Whether current doctors and medications remain covered.
The official Medicare.gov Open Enrollment resources provide the tools for comparing available plans once the 2027 offerings are available.

Related History or Comparable Technologies
The 2027 changes are part of a larger transformation of the Medicare prescription drug market.
The Inflation Reduction Act introduced major changes to Medicare Part D, including a redesigned benefit structure and a $2,000 annual out-of-pocket cap beginning in 2025. The cap was adjusted to $2,100 for 2026.
CMS’s July 2026 announcement also established a $296.05 national average monthly bid amount for 2027 and a $41.33 base beneficiary premium used in the statutory calculation of basic Part D premiums.
The defined standard Part D deductible is also scheduled to rise from $615 in 2026 to $700 in 2027, while the annual out-of-pocket threshold rises from $2,100 to $2,400.
That means the headline $36 average premium should not be viewed in isolation. The structure of the benefit and the costs consumers encounter when filling prescriptions are also changing.
What Happens Next
The immediate deadline is September 30, when Medicare Advantage and Part D insurers must provide beneficiaries with information about changes to their coverage.
Then comes Medicare Open Enrollment:
October 15 through December 7, 2026
Changes made during this period generally take effect January 1, 2027.
CMS says beneficiaries can use Medicare.gov during the enrollment period to compare their 2027 options.
One important caveat: the latest CMS announcement is primarily about Medicare Advantage and Part D. It should not be interpreted as the complete set of 2027 Medicare costs for every part of the program.
Conclusion
The new Medicare rates 2027 numbers paint a complicated picture.
Medicare Advantage’s projected average monthly premium falls to $12, while the average stand-alone Part D premium rises slightly to $36. At the same time, plan availability remains broad and the underlying benefit structure continues to evolve.
For beneficiaries, the practical question is not simply whether premiums are rising or falling. It is whether a specific 2027 plan will continue to cover the medications, doctors, hospitals and benefits they actually use at a manageable total cost.
With Open Enrollment beginning October 15, the next step is to review the plan-specific details rather than rely solely on national averages.
