Medicare Part D 2026: Costs, Changes & Enrollment Guide
If you're looking to understand the Medicare Part D changes for 2026, you're in the right place. Part D covers prescription drug costs and is an essential piece of your Medicare coverage—especially as plan costs and coverage limits continue to evolve.
What's New for Medicare Part D in 2026?
The Centers for Medicare & Medicaid Services (CMS) has updated the standard Part D benefit for 2026. Here's what's changing:
2026 Part D Deductible
- $615 maximum deductible (up from $590 in 2025)
Out-of-Pocket Threshold (TrOOP)
- $2,100 in 2026 (up from $2,000 in 2025)
How Medicare Part D Works in 2026
Medicare Part D includes several stages:
-
Deductible Stage – You pay 100% of drug costs up to $615.
-
Initial Coverage – After meeting the deductible, you pay a portion of drug costs (typically 25%) until you hit the coverage limit.
-
Catastrophic Coverage – Once you’ve spent $2,100 out-of-pocket, your costs drop dramatically. You may pay nothing or a small copay depending on your plan.
Tips for Choosing a 2026 Part D Plan
-
Compare plans early during Medicare Open Enrollment (Oct 15–Dec 7).
-
Check your current medications against each plan's formulary (covered drug list).
-
Balance the deductible vs. premium: A lower premium may have a higher deductible—and vice versa.
-
Consider bundling with Medicare Advantage (MA-PD) if you're looking for additional benefits beyond drug coverage.
