How Medicare Advantage Plans Make Money (and What that Means for You)

Medicare Advantage, also known as Part C, has grown in popularity as a way for Americans to receive their Medicare benefits.

Today, more than half of all Medicare-eligible individuals are enrolled in a Medicare Advantage plan rather than Original Medicare. But these plans are sold by private insurance companies, not the government, which raises a fair question: How do insurers profit from them, and does that affect the care enrollees receive?

The Government Payment Model

The foundation of Medicare Advantage is a monthly payment made by the federal government to private insurers for each enrolled member. The Centers for Medicare and Medicaid Services pay these companies a set amount per person based on factors like age, health status, and geographic location.

If an insurer can deliver care for less than that payment, it keeps the difference as profit. This arrangement creates a strong financial incentive for insurers to control costs wherever possible.

How Insurers Manage Risk and Revenue

Insurance companies use several strategies to improve their margins under this model. One of the most significant is called risk adjustment, where plans are paid more for enrollees with serious or complex health conditions.

Critics point out that some insurers have faced federal scrutiny for over-documenting diagnoses in ways that inflate their payments without necessarily improving patient care. In fact, a 2022 federal report found that Medicare Advantage overpayments totaled an estimated $11.4 billion in a single year, largely due to inflated risk scores.

Another way plans manage costs is by limiting which doctors, hospitals, and specialists enrollees can use. Narrow networks keep expenses predictable, but they can also restrict access for members who need specialized care.

Why Not Just Use Original Medicare?

Original Medicare covers roughly 80% of approved medical costs, leaving enrollees responsible for the remaining 20% with no out-of-pocket maximum. Medicare Advantage plans typically offer an annual cap on out-of-pocket costs, and many bundle in dental, vision, and prescription drug coverage at little to no extra premium.

These extras make the plans genuinely appealing, but they come with trade-offs, including prior authorization requirements, network restrictions, and plan changes that can occur year to year.

Understanding that private insurers are operating these plans as a business helps enrollees ask better questions during enrollment season. Coverage decisions, network limitations, and plan benefits are all shaped, at least in part, by the economics behind the product.
