Medicare beneficiaries are beginning to look ahead to next year’s healthcare expenses, and cms medicare plan rates 2027 are becoming an increasingly important topic as new premium and plan information is released. The latest figures show that Medicare Advantage premiums are projected to decline on average, while standalone Medicare Part D prescription drug premiums are expected to increase modestly. However, several important Medicare costs, including the standard Part B premium, have not yet received their final 2027 amounts.
The 2027 Medicare season will bring changes in premiums, deductibles, prescription coverage and plan availability. For millions of older Americans and people with disabilities, understanding these changes before Open Enrollment can make it easier to compare coverage and prepare a household budget.
Medicare Advantage Premiums Are Expected to Decline
One of the most significant developments for 2027 involves Medicare Advantage. These privately administered Medicare plans provide Medicare-covered benefits and often include prescription drug coverage along with additional benefits such as dental, vision and hearing services.
The Centers for Medicare & Medicaid Services projects that the weighted average monthly Medicare Advantage premium will be approximately $12 in 2027. That compares with an average of $14.37 in 2026.
The projected change represents a decline of about 16.5% in the national weighted average premium.
However, the national average should not be interpreted as the amount every Medicare Advantage enrollee will pay. Individual premiums depend on the specific plan, location and coverage selected. Some beneficiaries may have a $0 monthly plan premium, while others may pay more.
Monthly premiums are also only one part of the cost equation. Deductibles, copayments, coinsurance, prescription expenses and provider-network rules can significantly affect a beneficiary’s annual spending.
Medicare Advantage Enrollment Could Continue Growing
CMS estimates that Medicare Advantage enrollment could reach approximately 34 million people in 2027. That would represent roughly 47.4% of the overall Medicare population.
The agency also expects broad access to Medicare Advantage plans across the country. More than 99% of Medicare beneficiaries are projected to have access to at least one Medicare Advantage option, while approximately 97% are expected to have access to at least 10 plans.
The number of available plans is projected to remain relatively stable. CMS estimates approximately 5,532 Medicare Advantage plans could be available nationally in 2027, compared with 5,553 in 2026.
For current Medicare Advantage members, another important figure is the expected ability to remain with an existing plan. CMS estimates that roughly eight out of 10 Medicare Advantage beneficiaries will be able to remain in their current plan with the same or a lower premium.
That does not mean every existing plan will remain unchanged. Beneficiaries should still review their annual plan notices because networks, benefits, premiums and cost-sharing arrangements can change from one year to another.
Part D Prescription Drug Premiums Are Also Changing
Prescription drug coverage remains another major consideration for Medicare beneficiaries.
CMS projects that the average monthly premium for standalone Medicare Part D plans will be approximately $36 in 2027. The projected figure is less than $1 higher than the 2026 average of $35.09.
Although the average increase is relatively small, the actual premium paid by an individual can vary considerably depending on the plan and location.
CMS expects 88% of beneficiaries who do not receive low-income assistance to have access to a basic Part D plan costing $10.30 or less per month. The agency also projects that 93% of non-low-income beneficiaries will have access to an enhanced Part D plan costing less than $6 per month.
Beneficiaries should not select prescription coverage based solely on the monthly premium. A low-premium plan may have different costs for individual medications, pharmacies or coverage levels.
The Part D Deductible Will Be Higher in 2027
Another change that could affect prescription drug expenses is the Part D deductible.
For 2027, the standard Part D deductible is set at $700. That compares with $615 in 2026.
The deductible represents the amount a beneficiary may have to pay for covered prescription drugs before the plan begins paying according to the applicable benefit structure.
The increase could be particularly important for people who take expensive medications early in the year. However, the actual effect will depend on the person’s plan, drug list, pharmacy and available cost-sharing arrangements.
The annual Part D out-of-pocket threshold is also set at $2,400 for 2027. This figure is an important budgeting consideration for people who have substantial prescription expenses.
Medicare Advantage Drug Premiums Could Be Lower
Prescription coverage included within Medicare Advantage plans presents a somewhat different picture.
For Medicare Advantage plans that include prescription drug coverage, CMS projects that the average monthly Part D total premium after Medicare Advantage rebates will decline from $11.32 in 2026 to approximately $7 in 2027.
That represents a projected decrease of about $4.32 per month, or approximately 38%.
Again, this is a national average rather than a guaranteed price. Individual plan costs can differ significantly.
Beneficiaries considering Medicare Advantage should therefore examine the complete package rather than focusing exclusively on the advertised premium. A plan’s provider network, prescription formulary, copayments, specialist costs and annual out-of-pocket maximum can all influence the overall value and affordability of coverage.
The 2027 Part B Premium Has Not Been Finalized
For people enrolled in Original Medicare, the monthly Part B premium is one of the most important figures to watch.
The standard Part B premium for 2026 is $202.90 per month. The 2026 Medicare Trustees Report estimates that the standard monthly Part B premium could rise to $209.50 in 2027.
That $209.50 figure is a projection, not the final 2027 premium.
CMS traditionally announces the official Medicare Part B premium and deductible later in the year. Therefore, beneficiaries should wait for the final government announcement before using an estimated figure as their actual 2027 expense.
Part B covers physician services, outpatient care, certain medical equipment and many other medically necessary services. Because the premium is commonly deducted directly from Social Security payments, even a relatively small change can affect the amount deposited into a beneficiary’s bank account each month.
Higher-Income Beneficiaries May Pay More
Not every Medicare beneficiary pays the same Part B premium.
People with higher incomes can be required to pay an Income-Related Monthly Adjustment Amount, commonly called IRMAA. This additional charge can affect both Medicare Part B and Part D premiums.
IRMAA calculations are generally based on income information from a prior tax year. As a result, a beneficiary’s Medicare premiums may be affected by income that occurred well before the year in which the premium is charged.
Retirees who experience a significant reduction in income after a qualifying life-changing event may be able to request a reconsideration of their income-related Medicare adjustment.
This is one reason beneficiaries should carefully review Medicare premium notices and avoid assuming that the standard premium applies to everyone.
Why the National Average Does Not Tell the Whole Story
The latest cms medicare plan rates 2027 information provides useful national benchmarks, but consumers should remember that Medicare is not priced identically across the country.
Medicare Advantage plans are offered through private insurers and can differ substantially by county. A plan available in one ZIP code may not be offered in another.
Prescription drug coverage can also vary. Two plans with similar monthly premiums may charge very different amounts for the same medication.
For that reason, beneficiaries should consider their expected healthcare use when comparing coverage.
Someone who visits doctors frequently may want to examine specialist copayments and network rules. A person who takes several prescription medications may need to pay particular attention to drug tiers and pharmacy costs. Another beneficiary may place greater importance on dental, vision or hearing benefits.
The most appropriate plan depends on the individual’s circumstances rather than the national average premium.
Medicare Open Enrollment Begins October 15
The Medicare Open Enrollment period for 2027 coverage begins October 15, 2026, and ends December 7, 2026.
This period gives people with Medicare an opportunity to review their coverage and make changes for the following year.
During Open Enrollment, beneficiaries can compare Medicare Advantage plans, Part D prescription drug plans and other available coverage options.
Changes generally take effect January 1, 2027.
Beneficiaries should avoid waiting until the final days of Open Enrollment to review their options. Plan information can take time to compare, particularly for people who have several prescriptions or want to confirm that preferred doctors and hospitals remain within a plan’s network.
What to Check Before Choosing a 2027 Plan
A Medicare plan comparison should go beyond the monthly premium.
Beneficiaries should review whether their preferred doctors and hospitals participate in the plan. Prescription users should check whether all regularly prescribed medications remain covered and determine the expected cost at their preferred pharmacy.
Other important factors include the annual deductible, specialist copayments, hospital costs, emergency care expenses and the plan’s annual out-of-pocket maximum.
People who currently have Medicare Advantage should also review their plan’s annual notice of change. This document can identify modifications to premiums, benefits, networks and cost-sharing for the upcoming year.
Those with Original Medicare should separately consider whether their existing supplemental coverage and prescription drug arrangements continue to meet their needs.
Financial Assistance May Help Eligible Beneficiaries
Some Medicare beneficiaries may qualify for programs that help reduce healthcare or prescription expenses.
Medicare Savings Programs can assist certain people with Medicare costs depending on income and resource eligibility. The federal Extra Help program can also assist qualifying beneficiaries with prescription drug expenses.
Eligibility rules vary, and beneficiaries should review current requirements rather than assuming they are ineligible.
For people living on a fixed income, even modest savings on monthly premiums or prescription expenses can make a meaningful difference over the course of a year.
What to Expect as 2027 Approaches
The 2027 Medicare picture is becoming clearer, but some figures remain subject to final announcements.
Medicare Advantage beneficiaries have reason to pay close attention to the projected $12 national average monthly premium, while Part D enrollees should prepare for an average standalone premium of about $36 and a standard deductible of $700.
Original Medicare beneficiaries should continue watching for the official 2027 Part B premium and deductible announcement. The current $209.50 figure is only a projection from the Medicare Trustees and should not be confused with the final CMS rate.
Ultimately, Medicare beneficiaries should use national averages as a starting point rather than a personal price quote. The actual cost of coverage depends on the plan selected, location, income, prescriptions and healthcare needs.
As the 2027 enrollment season approaches, reviewing plan documents early and comparing total potential costs can help beneficiaries enter the new year with a clearer understanding of their Medicare coverage.
