Medicare Part D plans provide prescription drug coverage for Medicare beneficiaries, with key changes in 2026 under the Inflation Reduction Act capping out-of-pocket costs. Comparing plans involves evaluating premiums, deductibles, copays, formularies, and pharmacies based on your medications and location. Use Medicare.gov's Plan Finder tool during Open Enrollment (typically October 15–December 7) for personalized comparisons.

2026 Plan Basics

Part D features a $615 deductible (up from $590 prior year), 25% coinsurance in initial coverage until $2,100 out-of-pocket, then $0 in catastrophic phase. Base beneficiary premium averages $38.99, up 6% but capped by law. Plans vary by insurer, with no one-size-fits-all best option—Wellcare leads for low premiums and ratings, Humana for $0-premium availability nationwide.
