Medicare Advantage 2026: Enrollment Changes, Cost Increases, and Reduced Coverage Areas

The Medicare Advantage (MA) Open Enrollment Period for 2026 provides current enrollees the flexibility to switch plans or revert to original Medicare. This period runs from January 1 to March 31, with the stipulation that only one change can be made per enrollee. Medicare Advantage, also known as Medicare Part C, offers a bundled insurance solution that typically includes hospital, medical, and prescription drug coverage, often supplemented with additional benefits like dental and vision. While Medicare Advantage plans generally feature lower premiums and out-of-pocket limits compared to traditional Medicare, they come with more restrictive provider networks and referral requirements, which can impact access to care. Eligibility for Medicare Advantage is contingent upon residing in a county where these plans are offered, with a decreasing number of counties providing access in 2026. Notably, leading insurers like UnitedHealthcare and Humana are scaling back their Medicare Advantage presence, exiting numerous counties nationwide. This reduction narrows the availability of MA plans from 34 in 2025 to 32 in 2026, reflecting strategic adjustments driven by local market conditions, cost pressures, and profitability assessments. The Centers for Medicare & Medicaid Services (CMS) has announced that Medicare Advantage Prescription Drug (MA-PD) plan pricing will continue to be influenced by factors such as income and work history. Beneficiaries should anticipate rising costs and carefully evaluate plan options during enrollment to avoid service disruptions or limited provider access. This contraction in Medicare Advantage offerings is particularly pronounced in states including Alaska, California, Colorado, and several others, underscoring the importance for insurance professionals to monitor regional availability changes and counsel clients accordingly. Continued tracking of insurer market exits and entrance is critical for understanding evolving Medicare Advantage market dynamics in 2026.
