Medicare Spending was 27% More for People who Disenrolled from Medicare Advantage than for Similar People in Traditional Medicare

GAINING CLARITY: A KFF study analyzed Medicare spending for individuals who disenrolled from Medicare Advantage, revealing that their subsequent traditional Medicare spending was 27% higher, averaging $2,585 more per person. ▼

The increased spending was largely attributed to skilled nursing facilities, outpatient, and inpatient hospital care. The study raises questions about why individuals disenroll, the affordability of traditional Medicare without supplemental insurance, and the adequacy of the current Medicare payment system


More than half (54%) of eligible Medicare beneficiaries are enrolled in a private Medicare Advantage plan in 2024. People are drawn to Medicare Advantage because most plans offer extra benefits and lower cost sharing compared to traditional Medicare without supplemental insurance, usually for no additional premium (other than the Part B premium). Medicare Advantage is also popular among lawmakers in Congress, both Republicans and Democrats, as well as President-elect Trump, whose previous administration generally supported policies that provided increased flexibilities to insurers when designing and administering these private plans.

Though Medicare Advantage is a popular choice for Medicare beneficiaries, there is some evidence that people who use relatively more health care services are less likely to choose a private plan and more likely to choose traditional Medicare. Previous analyses from KFF and the Medicare Payment Advisory Commission (MedPAC) found that people who enroll in Medicare Advantage have lower Medicare spending in the years before they enroll than similar people who remain in traditional Medicare, even after controlling for health status. This pattern may be partly attributable to concerns about the tools Medicare Advantage plans typically use to manage utilization and costs, such as prior authorization requirements and provider network restrictions.
