Medicare prescription drug plans, known as Part D, help cover outpatient prescription medications for those eligible under Medicare. These stand-alone plans or those bundled with Medicare Advantage offer varying formularies, premiums, deductibles, and cost-sharing to manage drug expenses effectively. In 2026, major updates from the Inflation Reduction Act reshape affordability for millions of beneficiaries.

2026 Key Changes

New federal negotiations lower prices on 10 high-cost drugs like Eliquis, Enbrel, and Xarelto starting January 1, potentially saving Medicare $6 billion annually based on prior-year data. A $2,000 out-of-pocket cap applies to all Part D plans, eliminating the "donut hole" and capping yearly spending—beneficiaries hitting this reset annually without reenrollment in payment plans. Weight-loss drugs like GLP-1s may see midyear price cuts, while plan finders on Medicare.gov gain enhanced features for better comparisons.

How Plans Work

Part D plans feature tiers: generics often cost less, while brand-name drugs face higher copays unless negotiated lower. Enrollment occurs during Annual Enrollment (October 15–December 7), with penalties for late joiners; use Medicare.gov's Plan Finder by entering ZIP code, drugs, and pharmacies for personalized estimates. Insurers like Humana offer multiple options, but coverage varies by location—always verify your meds are on the formulary.

Choosing a Plan

  • Estimate costs : Input your prescriptions, dosage, and preferred pharmacy on Medicare.gov to sort by lowest total (premium + drug costs).
  • Compare tiers : Look for plans covering your drugs in low copay tiers; avoid gaps in high-use meds.
  • Check networks : Preferred pharmacies reduce out-of-pocket; mail-order options save more for maintenance drugs.
  • Review stars : CMS rates plans 1–5 stars for quality and service.
