The chair of Congress's Medicare advisory commission told an insurance industry audience on Sept. 22 that his agency stands behind its estimate that Medicare Advantage will cost taxpayers about $76 billion more this year than traditional Medicare would for the same people. Dr. Amol Navathe, who became chair of the Medicare Payment Advisory Commission, or MedPAC, in May, spoke at a Washington forum hosted by the Better Medicare Alliance, an influential Medicare Advantage lobby, Healthcare Dive reported.
Navathe, a medical ethics and health policy professor at the University of Pennsylvania who has served on the boards of two Medicare Advantage plans, said the finding that the program costs 14% more does not mean MedPAC is calling for a 14% cut to plans. He said the commission welcomes critiques. "There are opportunities for us to refine our methods and to improve our work, and we're aspiring to do that," he said.
The fight reaches household budgets. Extra spending feeds into the Part B premium that nearly every Medicare enrollee pays, including people who never joined a private plan. More than half of Medicare beneficiaries are now in Medicare Advantage, and open enrollment for 2027 coverage begins Oct. 15.
Inside MedPAC's 14% Figure
MedPAC's January estimate found that government payments to Medicare Advantage plans would be close to traditional Medicare spending without two factors, Healthcare Dive reported at the time. The first is favorable selection, when people who join private plans turn out to be healthier and less costly than expected. The second is coding intensity, when plans record more or more severe diagnoses than traditional Medicare would, which raises what the government pays.
MedPAC builds the estimate from people who switch from traditional Medicare into private plans and applies the results to the full enrollment. That choice sits at the center of the dispute. Some commissioners agree the method is imprecise but argue that the evidence of overpayments is clear, and MedPAC later revised its estimate for 2025 overpayments downward.
This is a modeled projection, not an audit, and it does not measure fraud.
Insurers Push Back as Congress Weighs a Rewrite
Insurers say MedPAC overstates the gap. Earlier this month, the Better Medicare Alliance published a white paper arguing MedPAC undercounts the value of Medicare Advantage, saying the method ignores basic differences between private plans that take on financial risk and fee-for-service Medicare. The group launched an advertising campaign aimed at policymakers in June. Plans also point to a CMS analysis from January that produced a much lower overpayment estimate, and to industry-funded research finding that Medicare Advantage saves money.
In a party-line vote this month, House Ways and Means Republicans advanced a bill requiring two spending comparisons, one that counts favorable selection and one that leaves it out. Democrats say the bill undermines MedPAC's independence, while insurer groups have urged Congress to pass it.
The administration is sending mixed signals. In a video shown at the same forum, CMS Administrator Dr. Mehmet Oz described Medicare Advantage as a garden "vulnerable to weeds and overgrowth," Healthcare Dive reported.
Premiums, Plans, and This Fall's Medicare Choices
The most direct household effect runs through Part B. A Joint Economic Committee analysis released in March, prepared by the committee's Republican majority staff, estimated that excess payments to private plans raised Part B premiums by $212 per enrollee in 2025, or $13.4 billion in total, Healthcare Dive reported. Since 2016, the report estimated, overpayments have added about $82 billion to Part B premiums, and traditional Medicare enrollees directly bore about $6 billion of that. That analysis builds on MedPAC's numbers, so it shares the disputed method. The Better Medicare Alliance said the findings "rely on flawed analysis and ideological bias."
Because Part B premiums are usually deducted from Social Security checks, higher premiums shrink take-home benefits. The heaviest burden falls on retirees living on fixed incomes, people with chronic illnesses who need frequent specialist care, and adult children who help aging parents compare coverage.
Nothing in this debate changes 2027 benefits on its own. During open enrollment, which runs from Oct. 15 to Dec. 7, enrollees can read their plan's Annual Notice of Change, confirm that their doctors and hospitals remain in network, check that their prescriptions are still covered, and compare total expected costs rather than premiums alone. Free, unbiased counseling is available through each state's State Health Insurance Assistance Program, known as SHIP.
The House bill still needs a floor vote, and Senate action is uncertain. MedPAC still says private plans cost about 14% more. The open question is whether Congress rewrites the math before it rewrites the payments, and the most useful step for enrollees now is a careful review of their options this fall.
Key Questions Answered
What is MedPAC's $76 billion estimate? It projects that the federal government will spend about 14% more, or $76 billion, on Medicare Advantage enrollees this year than it would if they were in traditional Medicare.
What drives the extra spending? MedPAC points to favorable selection, meaning healthier enrollees, and coding intensity, meaning more recorded diagnoses that raise payments.
Why do insurers object? They say MedPAC's method relies on people who switch into private plans and misses key differences between the programs, which they argue inflates the estimate.
Does this affect people in traditional Medicare? Possibly. A congressional analysis estimated that excess payments raised Part B premiums for all enrollees, though it relies on MedPAC's disputed numbers.
Will my 2027 plan change because of this? Not directly. Review your plan's Annual Notice of Change and compare options during open enrollment, Oct. 15 to Dec. 7.
Where can I get free help choosing a plan? Each state's SHIP program offers free, unbiased Medicare counseling.
