Medicare Advantage Enrollment and Disenrollment Among Persons With Alzheimer Disease and Related Dementias
Hannah O. James, Amal N. Trivedi, David J. Meyers. JAMA Health Forum, 2023-09-15
Topic: Risk, prevention and care in population studies
Results The 32 796 872 Medicare beneficiaries in the cohort had a mean (SD) age of 74.0 (12.5) years and included 18 228 513 females (55.6%). Differences in contract exit rates were associated with higher rates of disenrollment from Medicare Advantage to traditional Medicare among beneficiaries with ADRD vs those without ADRD (16.3% [95% CI, 16.2%-16.3%] vs 15.1% [95% CI, 15.1%-15.1%]). Conclusions and Relevance In this cross-sectional study of the Medicare population with acute and postacute care use, beneficiaries with ADRD had increasing enrollment in the Medicare Advantage program, proportional to the growth in overall enrollment, but their disenrollment from Medicare Advantage in the following year remained higher compared with beneficiaries without ADRD. The findings highlight the need to understand the factors associated with higher disenrollment rates and determine whether such rates reflect access or quality challenges for beneficiaries with ADRD.

Key findings
- Results The 32 796 872 Medicare beneficiaries in the cohort had a mean (SD) age of 74.0 (12.5) years and included 18 228 513 females (55.6%).
- Differences in contract exit rates were associated with higher rates of disenrollment from Medicare Advantage to traditional Medicare among beneficiaries with ADRD vs those without ADRD (16.3% [95% CI, 16.2%-16.3%] vs 15.1% [95% CI, 15.1%-15.1%]).
- Conclusions and Relevance In this cross-sectional study of the Medicare population with acute and postacute care use, beneficiaries with ADRD had increasing enrollment in the Medicare Advantage program, proportional to the growth in overall enrollment, but their disenrollment from Medicare Advantage
- The findings highlight the need to understand the factors associated with higher disenrollment rates and determine whether such rates reflect access or quality challenges for beneficiaries with ADRD.
Why it matters
This study found that Medicare beneficiaries with Alzheimer's disease and related dementias left Medicare Advantage for traditional Medicare at a slightly higher rate than those without dementia. It does not test any treatment or prevention for Alzheimer's disease, but it points to a need to understand whether these higher disenrollment rates reflect problems with access or quality of care.
