2027 Medicare Plan Costs Every Beneficiary Should Know

Overview

Planning ahead for Medicare plan costs is one of the most important steps you can take to protect your health and your wallet. Every year, the Centers for Medicare & Medicaid Services (CMS) updates Original Medicare plan premiums and benefits, which can directly impact what you’ll pay for healthcare.
For 2027, the picture is mixed. Part D premiums are on track to rise after a two-year cost-stabilization program comes to an end, while CMS had not yet released Medicare Advantage premium, enrollment, or plan-count figures as of this writing. Access to a wide range of plan choices has remained strong in recent years.
Below, we break down what’s confirmed about 2027 Medicare plan costs — and what’s still pending CMS’s fall announcements — so you know what to expect before the Annual Enrollment Period (AEP).

Medicare Part B Premium in 2027

The Medicare Part B premium is a key cost for most beneficiaries, since it covers outpatient care, doctor visits, and preventive services.

• CMS had not yet announced the 2027 standard Part B premium or deductible as of this writing; official figures are typically released in mid-November. For reference, the 2026 premium is $202.90 per month and the 2026 deductible is $283, both up from $185.00 and $257, respectively, in 2025.
• Historically, these premiums increase slightly each year, though the size of the increase varies from year to year.
• In addition to the monthly premium, beneficiaries are responsible for the annual Part B deductible and 20% coinsurance for most covered services.

Medicare Advantage Plan Costs in 2027

Medicare Advantage Plans (Part C) continue to be a popular option for those who want an alternative to, and/or additional benefits beyond, Original Medicare (Part A and Part B).

Premiums

• CMS had not yet released the 2027 average Medicare Advantage premium as of this writing; that figure is typically published in the agency’s fall “landscape” announcement (the 2026 figures were released on September 26, 2025). For reference, the 2026 average MA premium is $14.00 per month, down from $16.40 in 2025.
• This includes plans that cover prescription drugs and Medicare Advantage Special Needs Plans (SNPs).

Enrollment Trends

• 2027 Medicare Advantage enrollment and plan-access projections were not yet available from CMS as of this writing. For 2026, CMS projected enrollment of about 34 million beneficiaries (roughly 48% of all Medicare beneficiaries), with 99% having access to at least one MA plan and 97% having 10 or more plan options.

Medicare Part D Costs in 2027

Prescription drug coverage is undergoing a significant change for 2027.

Stand-Alone Medicare Part D Plans (PDPs)

• CMS had not yet published the enrollment-weighted average standalone Part D premium for 2027 as of this writing; that figure is expected alongside the fall Medicare Advantage and Part D landscape release. What is confirmed: the Part D national average monthly bid amount rose to $296.05 for 2027, and the base beneficiary premium rose to $41.33, up about 6% from $38.99 in 2026.
• CMS continues to reject outlier plans with excessive premium increases, though rising baseline costs mean actual 2027 premiums are expected to trend higher than 2026’s.

Part D in Medicare Advantage

• The 2027 average Part D premium for Medicare Advantage plans that include drug coverage had not yet been released by CMS as of this writing; expect it alongside the broader fall landscape announcement.

Premium Stabilization Demonstration Ending

• CMS is discontinuing the Part D Premium Stabilization Demonstration — the temporary program that helped hold standalone drug plan premiums down in 2025 and 2026 — at the end of CY 2026, returning the market to standard pricing conditions starting in 2027. CMS Administrator Mehmet Oz has said premiums are expected to rise “by less than $10 for most Medicare recipients, with many even seeing lower premiums” once plans finalize their bids, though that has not yet been confirmed with final 2027 plan-level premiums.

Common Questions About 2027 Medicare Costs

Will my Medicare Advantage plan change in 2027?
Possibly. While CMS’s 2027 premium figures are still pending, your specific plan may update benefits, networks, or costs regardless. Always check your Annual Notice of Change letter (ANOC).
Is Part B included in Medicare Advantage plans?
Yes. All Medicare Advantage plans include Part A and Part B coverage, but you still must pay your Part B premium in addition to any plan premium.
Can I switch from Part D to Medicare Advantage in 2027?
Yes, during the Annual Enrollment Period (Oct 15 – Dec 7, 2026), you can switch from a stand-alone Part D plan and other Medicare plan coverage you may have to a Medicare Advantage plan with drug coverage.

Bottom Line

For 2027, beneficiaries should prepare for higher Part D premiums as a temporary cost-stabilization program comes to an end, while Medicare Advantage premium and enrollment trends for 2027 were not yet available from CMS as of this writing.
