ATI Advisory analyzed Medicare Advantage (MA) enrollment data from the Center for Medicare and Medicaid Services to identify and explore trends in MA enrollment. Between 2023 and 2024, Medicare Advantage gained more than two million new enrollees, reaching more than 50% of the Medicare eligible population. Medicare Fee-For-Service enrollment continued to decline nationwide with a reduction of more than 700K enrollees over the same time. While major carriers continued to dominate enrollment nationwide, several smaller MA plans also considerably expanded their enrollment. Special Needs Plans (SNPs) also saw dramatic growth, with almost 1,400 plans serving more than 6.6 million beneficiaries.

Health Equity Perspectives from Individuals Experiencing LTSS Needs, and their Caregivers, from Historically Marginalized Communities

ATI Advisory’s qualitative research highlights the experiences of individuals with long-term services and supports (LTSS) needs and their caregivers in requesting, receiving, and providing LTSS. Using a community-based participatory framework in partnership with local organizations, ATI conducted six focus groups interviewing individuals and caregivers from key populations across race, ethnicity, language ability, gender identity, sexual orientation, and disability status about their experiences with LTSS. Discussions generated themes around barriers to accessing LTSS, insights on family and professional caregiving across cultures, financial constraints, the value of social community for individuals and their caregivers, and the impacts of equitable and inequitable LTSS. This work was supported by the Robert Wood Johnson Foundation.
