In 2021, the switching rate from Medicare FFS to Medicare Advantage was 6.5 times higher than the switching rate in the opposite direction.
Increased rates of switching from Medicare fee-for-service (FFS) to Medicare Advantage in recent years have contributed to Medicare Advantage enrollment growth, a study published in Health Affairs found.
The share of Medicare beneficiaries in Medicare Advantage has increased from 19 percent in 2007 to 50 percent in January 2023. Understanding the source of this growth can help project where Medicare Advantage enrollment is headed.
Researchers used the CMS Medicare Enrollment Database and the Risk Adjustment Processing System to assess how many beneficiaries switched from Medicare FFS to Medicare Advantage and vice versa between 2006 and 2022.
