The market for medicare advantage plans 2027 is entering a crucial period as insurers finalize premiums, provider networks, prescription drug coverage and supplemental benefits for the new coverage year. Medicare beneficiaries will soon have the opportunity to compare their existing coverage with the options available for 2027, making the fall enrollment season an important time to review healthcare needs and potential costs.
Medicare Advantage remains one of the most widely used alternatives to Original Medicare. These private Medicare-approved plans provide Part A and Part B coverage and, in most cases, include prescription drug coverage. Plans can also provide benefits that Original Medicare generally does not cover, including routine dental, vision and hearing services.
However, Medicare Advantage plans can change substantially from one year to the next. A plan that worked well in 2026 may have different premiums, copayments, drug coverage, provider networks or supplemental benefits in 2027.
Medicare Advantage in 2027: What Beneficiaries Need to Know
The Centers for Medicare & Medicaid Services has finalized important policies affecting Medicare Advantage and Medicare Part D for 2027.
CMS projects that its finalized Medicare Advantage payment policies will increase average payments to plans by 2.48%, or more than $13 billion, compared with 2026. When estimated risk-score trends are included, the projected increase is 4.98%.
These figures apply to payments made to Medicare Advantage organizations and should not be interpreted as a direct increase in premiums or benefits for individual members. What a beneficiary pays in 2027 will depend on the specific plan available in the person’s service area.
The plan-level details are particularly important because insurers determine their premiums, cost-sharing structures, provider networks and supplemental benefits within Medicare’s regulatory framework.
Will Medicare Advantage Premiums Increase in 2027?
There is no single nationwide Medicare Advantage premium for 2027.
Some plans may continue to advertise $0 monthly premiums, while others may charge an additional premium. A $0 Medicare Advantage premium also does not eliminate other healthcare expenses.
Beneficiaries generally continue paying their Medicare Part B premium while enrolled in Medicare Advantage unless another program provides assistance with those costs.
Potential expenses can include:
- Doctor visit copayments
- Specialist copayments
- Hospital costs
- Emergency care
- Outpatient procedures
- Prescription drug expenses
- Deductibles
- Coinsurance
- Out-of-network charges
The most useful way to compare plans is therefore to estimate the total amount a person could spend during a year rather than looking only at the monthly premium.
Someone who rarely uses medical services could have a very different experience from someone who regularly sees specialists, takes multiple prescriptions or expects surgery.
Prescription Drug Coverage Is a Major 2027 Consideration
Prescription coverage is particularly important for beneficiaries choosing a Medicare Advantage plan that includes Part D.
The Medicare Part D benefit continues to undergo significant changes following reforms enacted through the Inflation Reduction Act. For 2027, the redesigned benefit structure eliminates the former coverage-gap phase and maintains a $2,400 annual out-of-pocket threshold for covered Part D drugs.
After a beneficiary reaches the applicable annual out-of-pocket threshold, there is no cost sharing for covered Part D drugs during the catastrophic phase.
That does not mean every prescription will cost the same under every Medicare Advantage plan.
Plans can have different formularies, drug tiers, preferred pharmacies, utilization-management requirements and cost-sharing arrangements.
Before enrolling, beneficiaries should check every medication they currently take.
Important questions include:
- Is the medication included in the plan’s formulary?
- Which tier contains the drug?
- Is prior authorization required?
- Does step therapy apply?
- Is there a quantity limit?
- Is the preferred pharmacy nearby?
- Is mail-order service available?
- Has the medication changed tiers for 2027?
These details can make a substantial difference to annual prescription spending.
Part D Premium Changes Could Affect Some Beneficiaries
Another significant development for 2027 is the scheduled end of the Medicare Part D Premium Stabilization Demonstration for standalone prescription drug plans.
CMS has said that the demonstration will end after 2026 because insurers have gained more experience pricing plans under the redesigned Part D benefit.
For 2027, CMS has announced a national average monthly bid amount of $296.05 and a base beneficiary premium of $41.33.
These numbers are not the amount every Medicare beneficiary will pay. The actual premium depends on the specific prescription drug plan or Medicare Advantage plan.
The end of the stabilization program could contribute to differences in premiums among plans, making annual comparison more important for beneficiaries who have prescription coverage through Medicare.
Out-of-Pocket Limits Matter
One of the most important numbers in a Medicare Advantage plan is the annual maximum out-of-pocket limit for covered Part A and Part B services.
Medicare Advantage plans must establish an annual limit on what members pay for covered Medicare services. Once the applicable limit is reached, the plan generally pays the full cost of covered Part A and Part B services for the remainder of the year, subject to plan rules.
The exact limit can vary by plan.
This figure can be particularly important for people with chronic conditions, frequent specialist appointments, planned procedures or a greater likelihood of hospitalization.
A plan with a low monthly premium may have a different cost structure from a plan with a higher premium. Looking at the maximum out-of-pocket amount alongside premiums and copayments provides a more complete picture of potential financial exposure.
Provider Networks Could Change
A plan’s provider network is another critical part of the 2027 decision.
Medicare Advantage plans generally require members to follow network rules, although the details depend on the plan type.
HMO plans typically emphasize in-network care, while PPO plans generally offer additional flexibility for receiving care outside the network, usually at a higher cost.
Before choosing coverage, beneficiaries should verify that their preferred:
- Primary-care physician
- Specialists
- Hospitals
- Urgent-care centers
- Medical groups
- Pharmacies
are included in the plan’s 2027 network.
Checking the network for the upcoming year is important because provider participation can change.
A familiar doctor being covered under a plan in 2026 does not guarantee that the same doctor will remain in the network for 2027.
Supplemental Benefits Can Differ Significantly
One reason many beneficiaries consider Medicare Advantage is the availability of additional benefits.
Depending on the plan and eligibility requirements, supplemental benefits can include dental care, vision services, hearing benefits, fitness programs, transportation assistance and other services.
Some plans may also provide allowances or benefits related to over-the-counter products, nutrition or other eligible needs.
However, benefits are not standardized across all Medicare Advantage plans.
A plan might advertise dental coverage while imposing an annual allowance, network restrictions, service limitations or cost-sharing requirements. Another plan could offer a different structure.
For that reason, beneficiaries should examine the detailed evidence of coverage instead of relying on a plan’s headline benefit list.
Medicare Advantage Star Ratings Are Also Changing
Medicare uses a five-star quality-rating system to evaluate Medicare Advantage and prescription drug plans.
The ratings incorporate measures related to areas such as preventive care, management of chronic conditions, member experience and other aspects of plan performance.
CMS has made changes to the measures used in the Star Ratings program for 2027.
Some measures are being removed, while other quality measures are being introduced or modified as CMS continues adjusting how plan performance is evaluated.
Draft 2027 Star Ratings thresholds were also released to insurers during September, with final ratings expected as part of the annual Medicare plan information process.
Beneficiaries can use Star Ratings as one factor when comparing plans, but quality ratings should be reviewed alongside costs, provider access and prescription coverage.
Read the Annual Notice of Change Carefully
People already enrolled in Medicare Advantage should watch for their Annual Notice of Change.
The document outlines changes taking effect with the new plan year. It can contain information about premium adjustments, cost-sharing changes, prescription coverage, provider networks and supplemental benefits.
A plan may keep the same name while changing important financial or coverage details.
Look specifically for changes involving:
- Monthly premiums
- Deductibles
- Copayments
- Coinsurance
- Prescription tiers
- Covered medications
- Provider networks
- Dental benefits
- Vision benefits
- Hearing benefits
- Maximum out-of-pocket limits
Reviewing these changes before the enrollment deadline can prevent unpleasant surprises after January coverage begins.
When Can You Enroll or Change Plans for 2027?
The Medicare Annual Election Period runs from October 15 through December 7.
During this period, Medicare beneficiaries can review their coverage and make eligible changes for the following year.
Coverage selected during the Annual Election Period generally takes effect January 1.
There are also other Medicare enrollment opportunities for people who qualify. These include the Medicare Advantage Open Enrollment Period and certain Special Enrollment Periods triggered by qualifying circumstances.
CMS released updated 2027 enrollment and disenrollment guidance in August, covering eligibility, election periods and effective dates.
Because enrollment rules can vary depending on a person’s circumstances, beneficiaries should verify which election period applies to them before submitting an enrollment request.
How to Compare Plans Before Making a Decision
A practical comparison starts with personal healthcare information.
Make a list of every prescription medication currently being used. Then identify preferred doctors, specialists and hospitals.
Next, consider how often medical care is typically required.
Someone with regular specialist appointments may place greater importance on specialist copayments and network access. A person taking several expensive medications may focus more heavily on formularies, drug tiers and pharmacy networks.
People who travel frequently should also examine emergency and out-of-area coverage.
A useful checklist includes:
- Monthly premium
- Annual deductible
- Maximum out-of-pocket limit
- Primary-care costs
- Specialist costs
- Hospital costs
- Prescription expenses
- Drug formulary
- Doctor and hospital networks
- Dental, vision and hearing benefits
- Prior authorization requirements
- Travel and out-of-network coverage
Looking at all of these categories can provide a clearer picture than comparing premiums alone.
Could a $0 Premium Plan Still Cost More?
Yes.
A plan with a $0 monthly premium can still require copayments or coinsurance when healthcare services are used.
For example, a beneficiary could have no monthly Medicare Advantage premium but face costs for specialist visits, diagnostic tests, hospital care and prescriptions.
Another plan could charge a monthly premium while offering lower cost-sharing for certain services.
The better comparison depends on expected healthcare usage.
Beneficiaries should estimate both a normal-use scenario and a higher-use scenario. The maximum out-of-pocket limit can be particularly useful for understanding what could happen during a year involving significant medical treatment.
What Makes 2027 Different From Earlier Years?
Several developments make 2027 an important year for Medicare beneficiaries.
The Part D benefit continues operating under the redesigned prescription drug structure, with a $2,400 annual out-of-pocket threshold for 2027. The separate Part D Premium Stabilization Demonstration for standalone prescription plans is also scheduled to end after 2026.
At the same time, Medicare Advantage insurers are operating under updated payment policies and a changing quality-rating system.
These developments do not mean every beneficiary will experience the same cost increase or benefit reduction. Medicare Advantage is a local and plan-specific market, and two people living in different counties can face very different choices.
Final Outlook for 2027 Medicare Coverage
The upcoming enrollment season gives Medicare beneficiaries an opportunity to reassess their healthcare coverage before the new year.
The most important task is not simply finding the lowest advertised premium. A plan’s prescription coverage, provider network, cost-sharing requirements, maximum out-of-pocket limit and supplemental benefits can all influence the actual value of coverage.
The 2027 Medicare Advantage market will also reflect broader changes to Medicare’s prescription drug program and insurer payment policies.
Beneficiaries should review their Annual Notice of Change, confirm their medications and doctors, compare available plans in their area and examine the complete cost structure before making an enrollment decision.
For people who are satisfied with their existing coverage, a yearly review can still be worthwhile because plan benefits and networks are not guaranteed to remain unchanged.
The key dates remain especially important: the Annual Election Period runs from October 15 through December 7, while coverage changes generally begin January 1.
With plan information becoming available for the new year, consumers can use the fall enrollment period to determine whether their existing Medicare Advantage coverage continues to meet their healthcare and financial needs in 2027.
