Medicare Advantage plans make money from the federal government, not from you directly

Medicare Advantage plans (also called Part C) are run by private insurance companies, but they do not charge you a premium the way traditional health insurance does. Instead, the federal government pays each plan a fixed amount per month for every person enrolled. That payment comes from the Medicare trust fund — the same pool that pays for Original Medicare. The insurance company keeps whatever money is left after paying doctors, hospitals, and other medical costs. If they spend less than they receive, they profit. If they spend more, they lose money.

This payment model is called capitation. The government essentially says: "Here is a set amount per person per month. You manage their care and keep the difference." It is the reason Medicare Advantage plans can offer benefits that Original Medicare does not — like dental, vision, or hearing coverage — without charging you an extra premium. They are betting they can deliver those benefits and still come out ahead.

Key Takeaways

  • Medicare Advantage plans receive a monthly payment from the federal government for each enrolled person, not from premiums you pay.
  • Plans profit by spending less than the government payment, which creates an incentive to control costs and limit expensive treatments.
  • The government adjusts payments based on your health status, so plans that enroll sicker people receive higher per-person payments.
  • Plans also earn money from supplemental benefits like dental and vision, which they can offer without raising your premium.
  • Understanding how plans make money helps explain why they may deny certain treatments or steer you toward in-network providers.

How the government payment amount is set

The federal government does not pay every Medicare Advantage plan the same amount. The payment varies by geography, age, and health status. Plans serving rural areas may receive different payments than plans in cities. A plan covering a 65-year-old receives less than a plan covering an 85-year-old, because older people typically use more medical services.

Health status matters most. If you have diabetes, heart disease, or multiple chronic conditions, your plan receives a higher monthly payment to account for your expected medical costs. This system is called risk adjustment. It is meant to prevent plans from cherry-picking only healthy people and refusing to enroll sick ones. In practice, plans have strong incentives to identify and document every health condition you have, because each diagnosis increases the payment they receive from Medicare.

The Centers for Medicare & Medicaid Services (CMS) sets the base payment rates each year. In 2024, the average payment to a plan for a 65-year-old with average health was around $1,100 per month, but this varies significantly by state and county. Plans with high enrollment in sicker populations receive substantially more.

Why plans deny treatments and restrict networks

Because a plan's profit depends on spending less than its government payment, plans have a financial incentive to deny or delay expensive treatments. This is the core tension in Medicare Advantage: the plan makes more money if you use fewer services. A plan that approves every specialist visit and every advanced imaging test will lose money faster than one that requires prior authorization and limits access to certain providers.

This is why Medicare Advantage plans maintain narrow networks — they contract with fewer doctors and hospitals than Original Medicare covers. By steering you to in-network providers, plans negotiate lower rates and control which treatments are available to you. Out-of-network care is either not covered or covered at a much higher cost to you, which discourages you from seeking it.

Prior authorization — requiring the plan to approve a treatment before you receive it — is another cost-control tool. Plans use it to review whether a treatment is medically necessary according to their standards. Some denials are appropriate; others reflect the plan's financial interest in avoiding expensive care. You have the right to appeal any denial, but the process takes time and many people do not pursue it.

Supplemental benefits and how plans use them to attract members

Many Medicare Advantage plans offer benefits that Original Medicare does not cover: dental work, vision exams and glasses, hearing aids, fitness programs, or transportation to medical appointments. These are called supplemental benefits. Plans can offer them without raising your premium because they are betting these benefits will attract healthy members while costing less than the government payment they receive.

A dental benefit that covers cleanings and basic work is relatively inexpensive to deliver but very attractive to consumers. A plan that offers it can enroll more people, which means more government payments flowing in. The plan profits if the cost of delivering that benefit is lower than the additional revenue from enrollment. Plans also use supplemental benefits to build loyalty — if you value your dental coverage, you are less likely to switch plans during open enrollment.

However, supplemental benefits vary widely. One plan might cover two dental cleanings per year; another covers four. One might cover hearing aids up to $1,500; another up to $3,000. These differences reflect each plan's calculation of what they can afford to offer while remaining profitable.

Star ratings and quality bonuses

Medicare publishes quality ratings for every Medicare Advantage plan each year, called Star ratings. They measure things like member satisfaction, how well the plan manages chronic diseases, and how quickly members can see a doctor. Plans with higher Star ratings receive bonus payments from Medicare on top of their base capitation payment.

A plan rated 4.5 stars might receive an extra 5 percent payment from the government compared to a plan rated 3.5 stars. This creates another financial incentive: plans profit by improving quality metrics. However, the metrics measure what plans report, not always what members experience. A plan can score well on Star ratings by documenting that it offered preventive care, even if members found it hard to schedule appointments or had claims denied.

The bonus system also rewards plans for keeping costs down while maintaining quality, which aligns the plan's financial interest with the government's goal of controlling Medicare spending. But it does not always align with what is best for individual members, especially those with complex or expensive conditions.

What happens when plans lose money

Not every Medicare Advantage plan is profitable every year. Some plans lose money because they underestimated medical costs, enrolled sicker members than expected, or faced unexpected expenses. When a plan loses money consistently, it may withdraw from certain counties or exit Medicare Advantage altogether.

If your plan exits, you are notified by October and given options: you can join another Medicare Advantage plan, switch to Original Medicare, or enroll in a Medigap supplemental policy. The transition can be disruptive — you may lose your current doctors or have to change pharmacies — but you cannot be denied coverage in another plan or in Original Medicare because of your health status.

Some plans also raise out-of-pocket costs — copays, coinsurance, or deductibles — to improve their financial position. These changes take effect January 1 each year and are announced in the fall. If your plan raises costs significantly, you have the right to switch plans during the annual open enrollment period without penalty.

The difference between Medicare Advantage profit and Original Medicare cost

Original Medicare is run by the federal government directly. It does not operate for profit. The government pays doctors and hospitals according to a fee schedule, and members pay premiums, deductibles, and copays. The government's goal is to cover costs, not to generate profit.

Medicare Advantage plans, by contrast, are for-profit businesses. They aim to generate returns for their shareholders. This does not automatically make them worse for you — many members prefer Medicare Advantage because of the supplemental benefits and lower out-of-pocket costs. But it does mean the plan's financial incentive is to limit spending, while Original Medicare's incentive is straightforward to pay for care that is ordered.

Understanding this difference helps explain why Medicare Advantage plans often have stricter rules about which doctors you can see, which treatments are covered, and how much you pay out of pocket. The plan is managing its profit margin, not just managing your care.

Frequently Asked Questions

Do I pay a premium for Medicare Advantage?

Most Medicare Advantage plans have no premium beyond the Part B premium you already pay to Medicare. Some plans charge an additional monthly premium of $0 to $200, depending on the plan and your location. You always pay the Part B premium to Medicare itself, which is separate from any plan premium.

If a plan makes money by denying care, how do I know my treatment will be approved?

Plans must follow federal rules about what they can deny. They cannot refuse medically necessary care straightforward to save money. If a plan denies a treatment your doctor ordered, you can appeal the decision. Many appeals are successful, especially if you have documentation from your doctor that the treatment is necessary. You also have the right to request an independent review if the plan denies your appeal.

Why do some Medicare Advantage plans offer better benefits than others?

Plans calculate what they can afford based on the government payment they expect to receive, the health status of their members, and their target profit margin. A plan in a wealthy area with younger, healthier members may be able to offer richer benefits than a plan in a rural area with older, sicker members. Competition also matters — plans in areas with many competitors often offer better benefits to attract members.

Can a Medicare Advantage plan go out of business?

Yes. If a plan loses money for several years or fails to meet federal standards, it can be forced to exit Medicare or choose to withdraw. When this happens, members are given time to choose a new plan. You cannot be denied coverage elsewhere because of your health status or claims history.

Does understanding how plans make money help me choose one?

Yes. Knowing that plans profit by controlling costs helps you evaluate their networks, prior authorization policies, and Star ratings. A plan with a narrow network and strict prior authorization may be more profitable but harder to use. A plan with a broad network and fewer restrictions may cost the plan more but give you more flexibility. Your choice depends on which trade-off matters more to your situation.
