What Is Medicare Part D?
Medicare Part D is prescription drug coverage, and you can get it in two ways:
- As a standalone Part D plan with Original Medicare
- Built into a Medicare Advantage plan
Part D plans are run by private insurance companies, which means:
- Not all plans cover the same medications
- Drug costs can vary dramatically
- Each plan has its own network of pharmacies
The Truth About Part D: It’s Not One-Size-Fits-All
The best plan for your neighbor might be the worst one for you. Why?
Because every plan has:
- Different formularies (the list of drugs it covers)
- Different copays and coinsurance
- Different pharmacy networks
- Different tiers for the same medication
Example: One plan might charge $5 for your prescription, while another charges $150 for the exact same drug.
We’ve had clients save over $1,000 per year simply by switching plans—without changing a single medication.
Why You Must Review Your Plan Every Year
Part D plans can change every year during the Annual Enrollment Period (AEP), which runs October 15 – December 7.
If you don’t review your plan annually, you could:
- Lose coverage for your medications
- Pay much higher copays
- Miss out on lower-cost pharmacy options
The Big Change in 2025: No More Donut Hole
In 2026, Part D will have a major update:
- The donut hole is gone
- There’s now a $2,000 annual out-of-pocket cap for covered medications
Here’s how it works:
- Pay your plan’s deductible (if it has one)
- Pay copays or coinsurance for prescriptions
- Once your total out-of-pocket for covered drugs hits $2,000, you pay nothing for the rest of the year
This is especially good news if you take expensive brand-name medications—it could save you thousands compared to prior years.
