Your medication costs just got more predictable.
Thanks to major Medicare Part D changes in 2025, seniors nationwide now have an annual out-of-pocket cap of $2,000. No more surprise pharmacy bills. No more rationing medications.
But here’s what nobody tells you: choosing the wrong Part D plan can still cost you hundreds even with the new protections.
The average American senior takes 4.2 prescription medications monthly. Without Part D coverage, those medications could cost $400+ per month.
Medicare Part D isn’t just insurance. It’s your financial shield against rising drug costs nationwide.
Even better: You can now spread that $2,000 across monthly payments instead of paying large amounts upfront.
Remember: These are averages. Your costs depend entirely on which medications you take and which plan you choose.
Many states also offer additional prescription assistance programs that work alongside Medicare Part D.

Preferred pharmacies nationwide offer lower copays:
CVS/Target: Extensive network coverage Walgreens: Strong rural and urban presence
Walmart: Competitive pricing nationwide Costco: Often lowest prices for cash-paying customers Independent pharmacies: Personalized service but check network status
Mail-order pharmacies can save 10-15% on 90-day supplies for maintenance medications.
Medicare Part D won’t pay for:
Over-the-counter medications (unless prescribed) Vitamins and supplements Medical devices Medications covered by Part A or Part B Cosmetic products Medications purchased outside the United States.
Standalone Part D plans work with Original Medicare. You choose separate plans for medical coverage (Original Medicare + Medigap) and drug coverage (Part D).
Medicare Advantage with drug coverage bundles everything together. Most Medicare Advantage plans include Part D coverage, but check the formulary carefully.
Can’t have both: You cannot enroll in a standalone Part D plan if you’re in a Medicare Advantage plan that includes drug coverage.
Bottom line: The best Medicare Part D plan is the one that covers YOUR medications at YOUR preferred pharmacies for the lowest total annual cost.
Don’t let choice paralysis cost you money. The wrong decision costs seniors an average of $847 annually.
Take action during these enrollment periods:
New to Medicare: Enroll during your 7-month Initial Enrollment Period Current beneficiaries: Review plans every October 15 to December 7 Life changes: Use Special Enrollment Periods when eligible
Plans that don’t cover your most expensive medications Networks that exclude your preferred pharmacy Plans with excessive prior authorization requirements.
Medicare Part D isn’t just about saving money on prescriptions. It’s about removing the financial stress that keeps seniors from taking medications as prescribed.

You’ll face a lifetime late enrollment penalty if you go 63 or more days without creditable prescription drug coverage. The penalty equals 1% of the national average premium for each month you delayed enrollment. This penalty never goes away as long as you have Medicare Part D.
Not necessarily. Each Part D plan has its own pharmacy network. You can use out-of-network pharmacies, but you’ll pay significantly more. Most plans include major chains like CVS, Walgreens, and Walmart, plus many independent pharmacies. Always check if your preferred pharmacy is in-network before enrolling.
A formulary is your plan’s list of covered medications. A pharmacy network is the list of pharmacies where you can fill prescriptions at contracted rates. Both matter for your costs. A medication might be on the formulary but cost more at an out-of-network pharmacy.
Yes, but only during specific enrollment periods. The main opportunity is during Annual Open Enrollment (October 15 to December 7). You can also change during Special Enrollment Periods if you qualify due to circumstances like moving or losing other coverage.
Most Part D plans cover specialty medications, but they’re typically placed in higher tiers (Tier 4 or 5) with higher costs. Many require prior authorization or step therapy. If you need specialty drugs, carefully compare plans’ formularies and consider the total annual cost, not just monthly premiums.
