Medicare in 2026: Key Changes Every Retiree Should Know

Medicare is a moving target. Legislative changes, plan design evolution, and program updates mean that what was true about your coverage last year may not be true this year. Here is what has changed in 2026 that matters for current and soon-to-be Medicare beneficiaries.

The prescription drug landscape has continued to shift following the Inflation Reduction Act provisions phasing in. The redesigned Part D benefit structure has changed out-of-pocket exposure for beneficiaries with high medication costs significantly. The cap on annual out-of-pocket drug spending is now in effect, which changes the calculus on Part D plan selection for people with expensive ongoing prescriptions.

Medicare Advantage plan availability and benefit design has continued to evolve. Extra benefits like dental, vision, and hearing coverage remain common marketing differentiators, but benefit structures vary widely and the restrictions on provider access and prior authorization requirements deserve careful attention at annual enrollment. The trend toward narrower networks has continued in many markets.

Original Medicare supplemental coverage changes: Medigap premiums have continued to increase, and plan availability varies by state and age at enrollment. The comparison between Medigap plus Original Medicare and Medicare Advantage plans remains highly situation-dependent, but more tools are available to model the comparison than ever before.

Annual Enrollment Period runs October 15 through December 7. Review your plan each year rather than defaulting to automatic renewal. Your situation changes and so do the plans.
