In a significant change to the Medicare landscape, leading health insurers are announcing plans to scale back their Medicare Advantage offerings for the coming year. This decision comes amid anticipated reductions in government reimbursements, a trend that has been in motion since 2024 as the U.S. government aims to curtail spending on the program.
Medicare Advantage, a privately-managed insurance program catering to individuals aged 65 and older, as well as those with certain disabilities, is feeling the pressure as insurers navigate a complex financial environment. Notably, CVS Health’s Aetna division has revealed it will limit its prescription drug plans to 100 fewer counties in 2025. Humana follows suit, reducing its plan availability to 85% of U.S. counties, a decline from the current 89%. Meanwhile, UnitedHealth, which manages the largest Medicare Advantage program, will cease operations in 109 counties, directly impacting approximately 180,000 beneficiaries.
These modifications stem from factors such as unexpectedly high utilization of medical services within Medicare Advantage, prompting insurers to withdraw from less profitable markets. The combination of funding cuts from the Centers for Medicare and Medicaid Services (CMS), along with rising healthcare costs and increased patient service needs, has placed significant pressure on the industry. Bobby Hunter, who oversees UnitedHealth’s government programs, articulated these challenges: “The combination of CMS funding cuts, rising healthcare costs, and increased utilization have created headwinds that no organization can ignore.”
Furthermore, some insurers are opting to exit entire states as they confront declining government compensation and escalating operational costs. Humana plans to provide Medicare Advantage plans in 46 states come 2026, a reduction from 48 this year, while Aetna will limit its reach to 43 states and 2,159 counties, down from 44 states and 2,259 counties.
Amidst these changes, insurers are also adapting their plan offerings. Humana will introduce new plan types in four states, covering 177 counties, and 83% of its standalone prescription drug plans will experience premium reductions. In contrast, CVS Health is set to broaden its services for individuals eligible for both Medicare and Medicaid, expanding to 16 additional states.
As the Medicare Advantage market undergoes these transformations, an estimated 600,000 members will be affected by UnitedHealth’s move to discontinue over 100 plans, particularly those enrolled in preferred provider organizations that allow flexibility in provider selection.
The current landscape in Medicare Advantage showcases the interplay of financial pressures and health service demands, leaving many to speculate on the future of healthcare coverage for millions of Americans as the program marks its 60th anniversary.
