Why the cheapest Part D plan usually costs you more
This is the mistake I see most often: someone picks a Part D plan in Palm Beach County because it has the lowest monthly premium — maybe $0 or $5 — and then discovers in February that their blood pressure medication is on Tier 4 and costs $95 a month, when a different plan with a $12 premium would have put that same drug on Tier 2 for an $8 copay.
Part D plans don't all cover the same drugs the same way. Each plan has its own formulary — the list of covered medications — organized into tiers, and each tier has a different copay or coinsurance. Two plans from two different carriers, both technically "Medicare Part D," can have wildly different costs for the exact same prescription list depending on which pharmacy benefit manager and tier structure they use.
On top of that, 2025 and 2026 brought real changes: the $2,000 annual out-of-pocket cap on prescription drug costs is now in effect, which is a huge win for anyone on expensive medications. But you still have to pick a plan whose formulary matches your actual prescriptions, or you'll pay far more than necessary getting there.
How I actually compare Part D plans for clients
The only way to compare Part D plans correctly is to run your actual medication list — drug name, dosage, and quantity — against every available plan's formulary in your zip code. I do this for every client, and it's not unusual to find a $2,000+ per year difference between the "obvious" cheap plan and the plan that actually fits your prescriptions.
I also check which pharmacy you use. Some plans have preferred pharmacy networks — CVS, Publix, Walmart, Winn-Dixie — where your copay is meaningfully lower than at a non-preferred pharmacy. If you're loyal to a specific Publix pharmacy in Greenacres or Lake Worth, that matters to which plan makes sense.
Understanding the phases (and why they matter less in 2026)
Part D used to have four phases: deductible, initial coverage, the infamous "donut hole" coverage gap, and catastrophic coverage. The donut hole has effectively been closed for most people now that the $2,000 out-of-pocket cap applies. In practice, this means once you and your plan combined have paid $2,000 out of your pocket in a calendar year, your covered medications are free for the rest of the year — a dramatic improvement for anyone managing diabetes, heart conditions, or other expensive chronic prescriptions.
What if I don't take many medications right now?
Even if you're only on one or two generics, you still need a Part D plan (or Medicare Advantage plan with drug coverage bundled in) once you're Medicare-eligible. Skipping Part D when you're first eligible can trigger a late enrollment penalty that follows you for life — a permanent percentage added to your premium. I check every new Medicare client's creditable coverage history to make sure they avoid that penalty entirely.

Frequently Asked Questions
How do I know which Medicare Part D plan covers my medications in Florida?
You need to check each plan's formulary against your specific drug names, dosages, and quantities — premium alone tells you nothing about your real cost. We run this comparison for free using your exact medication list across every Part D plan available in your Palm Beach County zip code.
What is the Medicare Part D out-of-pocket cap in 2026?
As of 2025, Medicare set a $2,000 annual cap on out-of-pocket prescription drug costs under Part D, carrying into 2026 and 2027 with minor inflation adjustments. Once you hit that cap, covered medications are $0 for the rest of the calendar year.
What happens if I don't sign up for Part D when I'm first eligible?
If you go without creditable prescription drug coverage for 63 days or more after your Initial Enrollment Period ends, Medicare charges a permanent late enrollment penalty added to your Part D premium for as long as you have coverage. We check your history to help you avoid this.
Can I change my Part D plan every year in Florida?
Yes. During the Annual Enrollment Period, October 15 through December 7, 2026, you can switch to any available Part D plan for coverage starting January 1, 2027. We recommend re-checking your formulary every single year since plans change their covered drugs and tiers annually.
