Study flags weak Medicare Advantage penalties

Medicare Advantage is the privatized side of Medicare, and it now covers a bigger share of seniors than traditional Medicare. That makes oversight a real kitchen-table issue — not some niche regulatory fight. The new wrinkle is that researchers at Brown looked at how the federal government actually punishes plans when they break rules, and the answer is: mostly with fines, usually not with anything stronger. The study was published online May 4 in *JAMA Internal Medicine*. (jamanetwork.com) ### What did the researchers actually look at? They pulled federal enforcement data for Medicare Advantage contracts from 2010 through 2023 and matched it to plan characteristics and enrollment. The dataset covered 1,173 unique contracts and 844 enforcement actions. That gives a pretty broad picture of how CMS has been policing the program over time, not just a handful of headline cases. (jamanetwork.com) ### What kinds of punishments showed up? Mostly civil money penalties. CMS does have tougher tools — it can suspend marketing, suspend enrollment, suspend payments, or terminate contracts altogether. But the study says those heavier sanctions were much less common than fines. That matters because a fine is easier for a large insurer to absorb than a sanction that blocks g(jamanetwork.com)s, which helps show the gap between what regulators can do and what they usually do. (jamanetwork.com) ### How small were the fines? Small enough that the deterrent question becomes hard to ignore. The average penalty in the study worked out to about 0.06% of annual revenue for the contract involved. In other words, the punishment was often tiny relative to the size of the business. If a plan can keep enrolling members and keep collecting premiums, a modest fine may not do much to change behavior. (jamanetwork.com) ### What were plans getting punished for? The violations included things patients and doctors complain about all the time — inappropriate denials or delays of covered care, marketing problems, and other compliance failures. That is why this is not just an abstract governance story. These are the rules that shape whether someone gets steered into a plan with misleading information or gets stuck waiting on prior authorization for care that should move faster. (jamanetwork.com) ### Why does prior authorization keep coming up? Because it is one of the main ways Medicare Advantage plans manage costs. Plans often require approval before certain services are delivered, and that can create delays and paperwork even when the care is ultimately covered. CMS has spent the last few years tightening rules around prior authorization and marketing, which te(jamanetwork.com)orcement with real bite is another. (cms.gov) ### Why does this matter more now? Scale. Medicare Advantage enrollment passed 35 million in February 2026, meaning more than half of eligible Medicare beneficiaries now get coverage through private plans. When a program is that large, weak deterrence does not stay isolated. It can affect huge numbers of older adults, caregivers, physicians, and hospitals.

The point of the paper is less “one company did something shocking” and more “the enforcement design looks soft across the system.” Researchers also noted that sanctions were not spread evenly — some parent companies accounted for a big share of actions. But t(kff.org)(jamanetwork.com) ### So what is the bottom line? The study does not say Medicare Advantage plans are never punished. It says the punishment often looks too modest to scare large insurers straight. Basically, CMS has stronger weapons than the ones it usually uses. And now that Medicare Advantage is the dominant form of Medicare coverage, that mismatch matters a lot more. (jamanetwork.com)
