Medicare Advantage plans, also called Part C plans, combine coverage for hospital and medical services into one plan offered by private insurance companies approved by Medicare. In 2027, these plans will continue to have monthly premiums, though the exact costs vary significantly based on which plan you choose and where you live.

The monthly premium is what you pay to the insurance company each month to keep your plan active. This is separate from any premiums you pay for Medicare Part B (medical insurance). Many Medicare Advantage plans offer $0 monthly premiums, meaning you would only pay the Part B premium to Medicare itself. According to data from the Centers for Medicare and Medicaid Services, approximately 28 million people were enrolled in Medicare Advantage plans as of 2024, with more than half selecting plans that had $0 premiums.
However, a $0 premium does not mean the plan is free. You will have other costs when you use healthcare services. These other costs appear at the point of care—when you see a doctor, fill a prescription, or stay in a hospital. Plans charge different amounts for these services through copayments (a set dollar amount per visit), coinsurance (a percentage of the cost you pay), and deductibles (the amount you must pay before the plan starts sharing costs).
The amount insurance companies can charge for premiums changes each year based on what the plan costs to operate, how many people join, and regulatory decisions by Medicare. In recent years, premiums have remained relatively stable or even decreased in some regions, though this varies by plan and location. For 2027, plan designs and premium structures are still being finalized by insurers and approved by Medicare, so specific numbers for all plans are not yet publicly available.
Practical Takeaway: When reviewing 2027 Medicare Advantage plans, look beyond the monthly premium amount. Compare the total costs you might pay throughout the year by checking copayments for doctor visits, hospital stays, and prescriptions. A plan with a low or zero premium may have higher out-of-pocket costs when you receive care.
One of the key protections in Medicare Advantage plans is an annual out-of-pocket limit. This is the maximum amount of money you will pay during a calendar year for covered services. Once you reach this limit, the plan typically covers all remaining covered services at no additional cost for the rest of that year.

For 2027, the out-of-pocket limit is expected to be set by Medicare, though the exact figure has not yet been announced. In recent years, the limit has been around $7,000 to $7,500 for in-network services, though some plans may have higher limits. Plans are allowed to set their own limits, as long as they meet or stay below the maximum amount Medicare allows. This is different from original Medicare, which has no annual out-of-pocket limit, meaning your costs could theoretically be unlimited.
Understanding how your specific plan counts costs toward the out-of-pocket limit is important. Some plans count all copayments and coinsurance toward the limit, while others may have different rules for different types of services. For example, a plan might count copayments for doctor visits and hospital stays toward the limit, but may have special rules for prescription drug costs. You should review your plan's Summary of Benefits and Coverage document to understand exactly what counts.
The out-of-pocket limit applies to in-network services in most plans. If you receive care from an out-of-network provider, your costs may be higher, and the rules may differ. Some Medicare Advantage plans charge significantly more for out-of-network care or may not cover it at all except in emergencies. This is an important reason to understand your plan's network of doctors and hospitals before enrolling.
Consider this scenario: You enroll in a Medicare Advantage plan with a $7,200 annual out-of-pocket limit. In January, you have a hospital stay that costs $3,500 after insurance negotiation, and you pay $1,500 in coinsurance. In March, you have several doctor visits and tests totaling $1,200 in copayments. By July, you've had a knee procedure, and your remaining costs for the year total $4,500, bringing you to the annual limit. From that point through December, the plan covers all additional covered services at no cost to you.
Practical Takeaway: Review the out-of-pocket limit for any 2027 plan you are considering, and find out which services count toward it. If you expect significant healthcare needs, a plan with a lower out-of-pocket limit may provide better financial protection.
Copayments and coinsurance are the day-to-day costs you pay when you use healthcare services under a Medicare Advantage plan. These costs exist on top of any monthly premium you pay, and they directly affect your annual healthcare spending.

A copayment is a fixed dollar amount you pay for a specific service. For example, your plan might charge a $20 copayment for a primary care doctor visit, a $40 copayment for a specialist visit, or a $300 copayment for an emergency room visit. These amounts are set by the insurance company and can vary widely between plans. Some plans charge different copayments depending on whether you visit an in-network or out-of-network provider.
Coinsurance is a percentage of the cost you pay instead of a fixed amount. For example, a plan might cover 80 percent of the cost of an outpatient hospital procedure, meaning you pay 20 percent coinsurance. The actual dollar amount you pay depends on what the service costs. If a procedure costs $5,000, you would pay $1,000 in coinsurance. If it costs $10,000, you would pay $2,000.
In 2027, Medicare Advantage plans will continue to vary widely in their copayment and coinsurance structures. Some plans, often called "low-cost" plans, may have zero or very low copayments for primary care visits but higher costs for specialist visits or hospital care. Other plans may spread costs more evenly across different types of services. Plans may also offer different cost structures for preventive services versus other care. For example, Medicare requires all Medicare Advantage plans to cover certain preventive services with no copayment or coinsurance, such as annual wellness visits, cancer screenings, and vaccinations.
Real-world example: Plan A charges $15 for a primary care visit and 20 percent coinsurance for outpatient hospital services. Plan B charges $0 for a primary care visit but charges $50 for a specialist visit and 30 percent coinsurance for hospital services. If you see a primary care doctor four times per year and have one outpatient procedure that costs $2,000, Plan A costs $60 for visits plus $400 for the procedure ($2,000 × 20%), totaling $460. Plan B costs $0 for visits but $50 for a specialist if needed, plus $600 for the procedure ($2,000 × 30%), potentially totaling $650 or more. The best choice depends on your specific healthcare needs.
Practical Takeaway: Make a list of the healthcare services you used in the past year—doctor visits, specialist appointments, hospital care, or tests. Compare the copayments and coinsurance for these services across the 2027 plans you are considering to estimate your likely annual costs.
Most Medicare Advantage plans include prescription drug coverage, called Part D. This means your plan covers both medical services and medications in one combined package. The costs associated with prescription drugs are a significant part of your overall Medicare Advantage expenses and deserve careful attention.

Prescription drug costs in Medicare Advantage plans include a deductible, copayments or coinsurance for individual medications, and potentially additional costs if you use higher-cost drugs. The deductible is the amount you must pay out of pocket for medications before the plan begins to help pay. For 2027, the maximum deductible that plans can charge for prescription drugs has not yet been announced, but in recent years it has been around $500 to $575. Many plans have lower deductibles or no deductible at all.
Once you meet your deductible, you typically pay a copayment or coinsurance for
