Key Takeaways
- The Part D $2,000 out-of-pocket cap (effective 2025) provides major protection against catastrophic drug costs
- Extra Help (Low Income Subsidy) can reduce Part D premiums and copays to near zero
- Prescription discount cards like GoodRx can sometimes beat Medicare Part D prices
How Medicare Part D Can Help Save on Prescription Drug Costs
Medicare Part D is the primary prescription drug coverage for Medicare beneficiaries. In 2025, a landmark change took effect: the out-of-pocket maximum for Part D was capped at $2,000 per year. This means no Medicare beneficiary will pay more than $2,000 out-of-pocket for covered drugs in a plan year - a major improvement from previous years when catastrophic drug costs had no cap.
How Much Do Drugs Cost With Medicare Part D?
| Phase | 2026 Threshold | Your Cost |
|---|---|---|
| Deductible | Up to $615 | 100% until met |
| Initial coverage | $615–$2,000 OOP | Copays/coinsurance |
| Catastrophic coverage | After $2,000 OOP | $0 |
How Discount Programs Can Help Save on Prescription Drug Costs
GoodRx - Free discount card, sometimes beats Part D prices for generics
RxSaver - Comparison tool for local pharmacy prices
NeedyMeds - Connects patients with manufacturer patient assistance programs
Extra Help (Low Income Subsidy) - Federal program reducing Part D costs for low-income beneficiaries
State Pharmaceutical Assistance Programs (SPAPs) - State programs supplementing Part D
Extra Help Program
If your income is below 150% of the federal poverty level, you may qualify for Extra Help, which can reduce your Part D premium to $0 and copays to $1–$4 per prescription.
Comparing Medicare Part D and Prescription Discount Programs
For expensive brand-name drugs, Part D is almost always better due to the $2,000 annual cap. For inexpensive generics, discount programs like GoodRx can sometimes offer lower prices than your Part D copay. You cannot use GoodRx and Part D simultaneously for the same prescription - choose whichever is cheaper for each medication.
Limitations of Prescription Drug Discount Programs
Discount program purchases don't count toward your Part D out-of-pocket maximum
Discount programs don't provide the same legal protections as insurance
Prices vary by pharmacy and can change without notice
Manufacturer coupons typically cannot be used with Medicare
