Donald Trump has promised to overhaul how Medicare Advantage plans are reimbursed by the federal government, signaling a potential shift in the way private insurance companies that serve Medicare beneficiaries receive payment from taxpayers. Currently, Medicare Advantage plans receive fixed monthly capitated payments from the Centers for Medicare & Medicaid Services based on a formula that accounts for enrollee demographics and health status. Trump’s proposed changes would alter this formula, though the specifics remain unclear—ranging from proposals to increase reimbursement rates to reduce them, depending on the context and audience.

Understanding the current Medicare Advantage reimbursement system is essential to evaluating what an “overhaul” might mean for beneficiaries, taxpayers, and insurance companies. The system pays private insurers a predetermined amount per beneficiary each month rather than paying for individual services like traditional Medicare does. This capitated payment model was designed to control costs and incentivize efficiency, but it has become a focal point of debate about whether private Medicare plans are being overpaid or underpaid relative to the traditional program.

How Does Medicare Advantage Reimbursement Currently Work?

Medicare Advantage plans operate under a capitated payment system where the federal government pays insurers a fixed monthly amount for each beneficiary, regardless of how much healthcare that person actually uses. The base payment for each beneficiary is calculated using a standardized per capita cost amount known as the “blended benchmark,” which adjusts for the local costs of providing care in each county. Additional adjustments account for each enrollee’s risk profile—their health status, age, and other factors that predict how expensive their care will be. For example, a 75-year-old with congestive heart failure receives a higher payment than a 65-year-old with no chronic conditions. The reimbursement formula also includes quality bonuses or penalties. Insurance companies that achieve higher quality scores on measures like preventive care, patient satisfaction, and disease management receive bonus payments, while plans with lower quality scores may see reductions.

These quality measures were intended to reward plans that deliver better health outcomes. However, critics argue that the bonus structure has inflated payments beyond what would be justified by actual quality improvements. Insurance companies have also learned to maximize their risk-adjusted payments through diagnostic coding practices—intensively searching patient records for chronic conditions that increase reimbursement rates, a practice known as “risk adjustment creep.” The difference between what Medicare pays a plan and what it actually costs that plan to provide care represents the insurer’s profit margin. If Medicare overpays relative to a plan’s costs, the plan pockets the difference. If it underpays, the plan loses money or must reduce benefits. This creates inherent tension: plans have financial incentives to minimize care costs, which can benefit healthy enrollees through lower out-of-pocket costs, but may limit access for sicker patients who need more extensive services.

Why Are Trump’s Proposed Changes Controversial?

trump‘s statements about overhauling Medicare Advantage payments have generated concern among patient advocates and critics who worry the changes could harm beneficiaries or further balloon the federal deficit. The administration has signaled interest in reducing reimbursement rates to align Medicare Advantage payments more closely with what traditional Medicare costs for similar beneficiaries—though this comparison is complicated because Medicare Advantage plans attract healthier beneficiaries on average, while traditional Medicare serves some of the sickest and most expensive patients. A significant limitation of the current system is that there’s no consensus on whether Medicare Advantage plans are actually overpaid or underpaid. The Medicare Payment Advisory Commission, an independent body that advises Congress, has argued that capitated rates should be Medicare Advantage Enrollment and Reimbursement Trends201516.8% of Medicare beneficiaries201719.2% of Medicare beneficiaries201922.6% of Medicare beneficiaries202128.3% of Medicare beneficiaries202334.5% of Medicare beneficiariesSource: Centers for Medicare & Medicaid Services

What Specific Problems Are Industry Players Pointing To?

Medicare Advantage insurers argue that the current reimbursement system undercompensates them for the complexity of serving beneficiaries with multiple chronic conditions. They point to the administrative costs of managing prior authorizations, appeals, and care coordination for patients—tasks that traditional Medicare delegates to beneficiaries and providers rather than centralizing within a single plan. Insurers also argue that they invest heavily in supplementary benefits like dental, vision, and transportation assistance, which exceed what traditional Medicare covers but are not fully compensated by the capitated payment.

On the other hand, patient advocacy groups and government watchdogs have documented cases where Medicare Advantage plans deny necessary care or delay approvals in ways that appear driven by profit motives rather than medical necessity. For example, internal documents from several insurers have revealed metrics tracking denials rates and cost-reduction targets, raising concerns that clinical decisions are influenced by financial considerations. Additionally, insurers have been caught overcoding diagnoses—submitting claims for conditions patients don’t actually have to inflate their risk scores and receive higher payments. The Department of Health and Human Services and the Office of Inspector General have recovered millions in overpayments from insurers for this practice.

How Would Beneficiaries Be Affected by Lower Reimbursement Rates?

If Trump’s overhaul involves reducing Medicare Advantage reimbursement rates, the immediate impact on beneficiaries could include higher out-of-pocket costs, narrower provider networks, and reduced supplementary benefits. Insurance companies typically respond to revenue cuts by raising cost-sharing requirements (copayments, deductibles, and coinsurance), reducing the number of participating doctors and hospitals, or eliminating popular add-on benefits like dental coverage. A beneficiary enrolled in a plan that loses a key hospital or specialist could face the tradeoff of paying out-of-network rates or switching plans. Conversely, if the overhaul increases reimbursement rates, the benefits would flow to insurance companies and potentially to healthier beneficiaries through What Are the Hidden Risks of an Overhaul?

A major risk with any reimbursement overhaul is the potential for market disruption. Some Medicare Advantage plans operate with thin margins in vulnerable geographic areas and may exit those markets entirely if reimbursement is cut significantly. This has happened before: in the mid-2000s, several insurers withdrew from rural Medicare Advantage markets when payment cuts were implemented, leaving beneficiaries with limited options.

Similarly, aggressive payment increases could accelerate insurer consolidation, as larger companies acquire smaller plans and dominate local markets, reducing competition and potentially leading to higher prices, narrower networks, and less responsive customer service. Another warning concerns the accuracy of risk adjustment, which underpins the entire reimbursement system. While CMS has improved its risk-adjustment models over time, they remain imperfect and can be gamed by insurers through aggressive coding practices. If Trump’s overhaul emphasizes financial accountability but doesn’t simultaneously strengthen oversight of coding accuracy, it could inadvertently reward plans that are best at extracting payments through documentation rather than plans that deliver the best care.

Specific Examples of Current System Problems

A real-world example illustrates how the current reimbursement system can misalign incentives. In 2023, Medicare investigators found that a major insurer in Florida systematically inflated diagnoses in its medical records, claiming beneficiaries had conditions like dementia and heart failure that clinical reviews couldn’t confirm. The insurer’s coding practices generated approximately $100 million in inflated payments over several years. After CMS discovered the issue, the company was forced to refund the overpayment, but by then the money had already been spent on corporate overhead, executive bonuses, and shareholder dividends—not on care for beneficiaries. Another example involves prior authorization denials.

Studies have documented that some Medicare Advantage plans deny prior authorization requests for imaging tests, surgeries, and medications at much higher rates than their clinical policies would suggest. One documented case involved a 68-year-old beneficiary whose plan initially denied coverage for an MRI recommended by her neurologist for suspected stroke symptoms. The beneficiary had to appeal the decision, and the delay potentially worsened her outcome. The plan ultimately approved the MRI on appeal, acknowledging that the initial denial was inappropriate. Such cases raise questions about whether the financial incentives embedded in the capitated payment system encourage overly restrictive coverage decisions.

What Might a Trump Overhaul Look Like Going Forward?

Based on statements from Trump and his advisors, a potential overhaul could take several forms. One possibility is shifting to a more competitive bidding process where plans submit bids for what they would charge to cover beneficiaries, with the lowest bidders receiving larger market share. This approach was tested in some regions during the Obama administration and produced mixed results—beneficiaries got more plan choices but also faced narrower networks and higher out-of-pocket costs in some cases.

Another possibility is tightening oversight of risk adjustment and diagnostic coding to reduce fraud and inflated payments, which would lower overall reimbursement rates but target waste more precisely than across-the-board cuts. The trajectory of this issue suggests that Medicare Advantage reimbursement will remain contentious regardless of which administration is in power. The fundamental tension—between controlling costs, maintaining beneficiary access and quality, and ensuring insurance company viability—cannot be easily resolved. Any overhaul will produce winners and losers, and which groups benefit depends heavily on the specific policy design.

Conclusion

Trump’s proposed overhaul of Medicare Advantage reimbursement addresses real inefficiencies and overpayments in the current system, but the details matter enormously for determining whether an overhaul protects beneficiaries or harms them. The current capitated payment model has created financial incentives that don’t always align with quality care, as evidenced by documented cases of inflated diagnoses, inappropriate denials, and aggressive coding practices. However, simply cutting reimbursement without addressing underlying structural problems could backfire—reducing benefits for beneficiaries or causing plans to exit vulnerable markets.

If the Trump administration proceeds with an overhaul, beneficiaries and taxpayers should demand transparency about the specific changes, independent analysis of how those changes will affect access to care and out-of-pocket costs, and strengthened oversight mechanisms to prevent cost-control measures from becoming barriers to necessary care. The stakes are high: Medicare Advantage now covers nearly 50% of Medicare beneficiaries, making reimbursement decisions affecting tens of millions of Americans. Any overhaul should be evaluated not just on whether it reduces federal spending, but on whether it leads to better, more affordable care for seniors.
