The Medicare Advantage plans of 2026 go through tremendous changes directly impacting millions of Americans. Enrollment decreases for the first time in three decades and large insurers withdraw their coverage for hundreds of counties. It becomes extremely vital to comprehend the changes to make well-informed decisions about health care.
The Medicare Advantage open enrollment takes place between October 15th and December 7th of 2025. It gives beneficiaries little time in between to cope with significant market disruptions. Here's everything you need to know about choosing the right plan for the year 2026.
What Are Medicare Advantage Plans and How Do They Work?
Medicare Advantage plans (Part C) serve as an alternative to Original Medicare. They combine hospital insurance (Part A), medical insurance (Part B), and typically prescription drug coverage (Part D) into one comprehensive plan offered by private insurance companies.
Original Medicare differs in certain aspects. Those plans could also consist of some added benefits such as:
- Dental, vision, as well as hearing
- Advantages of prescription
- Wellness programs and fitness membership
- Transport facility
- Over-the-counter allowances
The primary difference consists of network limitations. Traditional Medicare lets you go anywhere in the nation to see any doctor who accepts Medicare. Medicare Advantage plans all require utilization of the provider in their individual network, as employer plans for health insurance do.
Major Medicare Advantage Changes Coming in 2026:
1. Significant Market Contractions
The three largest Medicare Advantage carriers are broadly withdrawing from territories. UnitedHealthcare still holds the number one spot as market leader but declines coverage from 2,896 counties in 2025 to 2,787 counties in 2026. That 4% retreat costs an estimated 180,000 members. It also involves an outright withdrawal from the state of Vermont.
Humana is implementing the most aggressive scaling back. The company reduces coverage by 6.8% in 194 counties. Humana is completely withdrawing from North Dakota, South Dakota, and Puerto Rico. Aetna (CVS Health) is scaling back by 100 counties and includes a complete exit from Wyoming.
These changes mostly impact rural and less lucrative market segments. Seniors might end up having fewer options for plans or having had to change carriers altogether.
2. Premium Changes and Cost Implications
Premium declines in market contractions provide an intriguing comparison to premium estimates. CMS estimates median Medicare Advantage premium declines from $16.40 in 2025 to $14.00 in 2026. That includes an impressive 14.6% decrease. This big-headline number obscures significant cost movements at the individual-plan level.
Insurers maintain $0 premium offerings to remain competitive while increasing other costs such as:
- Higher copays and deductibles
- Increased out-of-pocket maximums
- Reduced supplemental benefits
- Narrower provider networks
Medicare Advantage enrollment is projected to decline from 34.9 million in 2025 to 34 million in 2026. This marks the first decrease in nearly two decades. This represents a shift from 50% to 48% of Medicare beneficiaries choosing Advantage plans over Original Medicare.
3. Special Needs Plans Drive Growth
General Medicare Advantage enrollment agreements as Special Needs Plans (SNPs) see record growth. Chronic Condition SNPs (C-SNPs) grew 42% to 556 plans in 2026.
The enrollment in the C-SNPs increased by 476,300 new members during the period 2024-2025. It's an increase of 70.6% and accounts for 75% of all SNP growth. It was due to the new CMS requirements for the Dual Eligible SNPs (D-SNPs) that went into effect in 2025. It aligns the requirements for the C-SNPs more favorably toward insurance companies as well as eligible members. These exclusive plans serve people who have certain chronic disease states like diabetes, heart disease, or mental illness. They provide individualized benefits as well as care coordination.
