1012-P: Trends in Enrollment in Medicare Advantage Plans among Older Adults with Diabetes, 2015–2020

Abstract

Existing literature has found an increase in the proportion of older adults that enroll in Medicare Advantage (MA) plans relative to those enrolling in traditional Medicare (TMed). Similarly, previous studies have shown that individuals with diabetes are more likely to enroll in MA plans than those without diabetes. Our objective was to determine whether trends for enrollment in MA plans among adults with diabetes followed a similar trend to those without diabetes. We used the Medicare Current Beneficiary Survey (MCBS) to calculate the proportion of the Medicare-eligible population enrolling in MA vs. TMed each year from 2015 - 2020. We stratified these rates by diabetes diagnosis (any diabetes vs. no diabetes), and further by diabetes type (Type 1 vs. Type 2). Like previously published literature, we found that those with diagnosed diabetes has higher rates of MA enrollment than those without diabetes. MA enrollment trends followed a similar pattern among those with diabetes compared to those without. Among those without diabetes, MA enrollment rates increased from 34.2% in 2015 to 40.5% in 2020. Among those with Type 1 and Type 2 Diabetes, MA enrollment rates increased from 38.8% to 46.9% and from 38.4% to 45.8%, respectively. In relative terms, MA enrollment increased by 20.9% among those with Type 1 Diabetes, 13.9% among those with Type 2 Diabetes, 15.9% with other diabetes, and 18.3% without diabetes.
