Part D is the trickiest piece of Medicare because the "right plan" depends entirely on your specific medications. Two clients on identical Medicare Supplements may end up on completely different Part D plans because their drug lists differ. A client taking three generic medications and a name-brand inhaler will have very different optimal-plan economics than a client taking the same three generics plus a $4,800-a-year specialty injection.
The Medicare.gov plan finder, run honestly with your actual medications, your actual pharmacy, and your zip code, ranks every Part D plan in your area by total annual cost (premium + deductible + copays through the year). It produces a number we can compare across plans. That number — your modeled annual cost — is the right basis for the decision, not the headline premium.
We re-run that comparison every AEP for every client. Most clients stay on the same plan year over year. A meaningful minority — maybe 15–25% in any given fall — switch. The reason is almost always either a formulary change (the plan moved one of your medications to a higher tier) or a medication change (you started a new prescription mid-year that the old plan handles badly).
How Part D works
- The Four Phases of a Part D Plan Year (2026)
- Annual deductible: Up to $615 (most plans). You pay 100% of drug costs until you hit it.
- Initial coverage phase: After the deductible, you pay your tier-based copays/coinsurance until your total drug spending reaches $5,030.
- Coverage gap (donut hole) — REDESIGNED: The IRA eliminated the traditional gap. You now pay no more than 25% of drug costs in this phase; once your out-of-pocket reaches $2,100, you enter catastrophic.
- Catastrophic coverage: $0 copay on covered drugs for the rest of the calendar year. Your annual Part D out-of-pocket is capped at $2,100 in 2026.
- Medicare Prescription Payment Plan (optional): Smoothes your $2,100 cap into even monthly payments across the year if you prefer.
What we do for you
- The Part D Conversation, Every Year
- You bring your full medication list — name, dose, frequency, preferred pharmacy
- We enter it into the Medicare.gov plan finder with your zip code
- The tool ranks every available Part D plan by total annual cost
- We discuss the top 3–5 plans and explain why each ranks where it does
- We file the enrollment if you change plans; we print and hand you the comparison if you stay
- We re-run this comparison every AEP, every year, for the life of the client relationship
A client switched her cholesterol medication from Lipitor to atorvastatin in March. By October her old Part D plan was the wrong plan — the new generic placed her in a different tier and her preferred pharmacy was an out-of-network for that particular tier. AEP is the moment we re-run that comparison. Every year.
Stand-alone Part D carriers we use
Wellcare Value Script. Often the lowest-premium standalone Part D plan in North Carolina ($0–$1/month in some zip codes). Formulary is tighter than competitors — best for clients on common generics with few brand-name medications.
Humana Walmart Value Rx. Lowest cost for clients whose preferred pharmacy is Walmart. Strong tier-1 generic pricing. The Humana Premier plan is a step up for clients on more expensive medications.
Aetna SilverScript. Three SilverScript tiers (SmartRx, Choice, Plus) covering a range of medication profiles. Aetna's pharmacy network is large; for clients who use a non-Walmart, non-CVS pharmacy, SilverScript Choice is often the right answer.
Cigna SecureRxRider. Cigna's mid-tier Part D plan. Pairs well with Cigna Healthspring Advantage clients who later switch to a Supplement.
Mutual of Omaha Rx. Newer standalone Part D entrant. Competitive for clients on moderate-tier brand-name medications. We model it routinely when comparing.
Frequently asked questions
How is the right Part D plan chosen?
By total annual cost using your specific medication list, your zip code, and your preferred pharmacy. We use the Medicare.gov plan finder. Two clients with similar diagnoses can land on different plans because their drug lists or pharmacies differ.
What happened to the donut hole in 2025?
The Inflation Reduction Act eliminated the traditional coverage gap. The 2025 redesign capped out-of-pocket Part D spending at $2,000 (2026: $2,100). The Medicare Prescription Payment Plan optionally smoothes the annual cap into monthly payments across the year.
Can I stay on the same plan year after year?
You can, but you probably shouldn't without a yearly review. Formularies change, tiers shift, premiums move. We re-run the plan finder every AEP for every client.
What is the late enrollment penalty?
If you go 63 or more days after becoming Medicare-eligible without creditable drug coverage, CMS imposes a permanent penalty: about 1% of the national base premium ($36.78 in 2026) per uncovered month, added to your premium for life.
Do you check my specific medications?
Yes, every appointment. We enter every medication into the plan finder. The appointment includes a printed copy of the comparison.
What if I switch a medication mid-year?
Mid-year medication changes are common. The plan-change opportunity is the next AEP (October–December), unless a Special Enrollment situation applies. Note the change and bring it to your fall appointment.
