Medicare Advantage in 2026: What You Need to Know

Medicare Advantage (Part C) is offered by private insurance companies as an alternative to Original Medicare. These plans bundle Part A and Part B coverage — and usually Part D — into a single plan, often with additional benefits like dental, vision, and hearing coverage. In 2026, more than half of all Medicare beneficiaries are enrolled in Advantage plans.

Key Changes for 2026

Several significant changes affect Medicare Advantage plans in 2026. CMS has implemented stricter prior authorization requirements, updated Star Rating methodologies, and increased oversight of provider directory accuracy. Some plans are also reducing supplemental benefits like meal delivery, transportation, and over-the-counter allowances.

Network Changes and Access

One of the biggest concerns for 2026 is network adequacy. Some plans have narrowed their provider networks, which can affect access to preferred doctors and specialists. If your doctor leaves your plan's network, you may face higher costs or need to switch plans during the next enrollment period.
