Medicare Prescription Drug Plans (Part D)

Affordable Access to Medications You Need

Prescription drugs are one of the biggest ongoing healthcare costs for retirees. That’s where Medicare Part D comes in. Part D plans are private insurance plans approved by Medicare that help pay for your medications.

Find a Medicare Part D plan that covers your medications. Part ABC compares drug plans and helps you avoid late-enrollment penalties.

Why The Right Plan Matters

Every Part D plan covers a specific list of drugs (its "formulary"), and each drug sits in a pricing tier. Two plans can have wildly different costs for the same prescription depending on how they tier it. That's why the "cheapest premium" plan isn't always the cheapest plan for you. The math depends on the exact medications you take.

How We Help You Choose

We look at your actual medication list, then compare plans on what they'd cost you for those specific drug premiums, plus what you'd pay at the pharmacy across the year. The goal is your lowest total cost, not just the lowest sticker price.

Don't Skip It The Late Penalty Is Permanent

If you go without creditable drug coverage after you're first eligible, Medicare adds a late-enrollment penalty to your premium, and it sticks for as long as you have Part D. Even if you take no medications today, enrolling on time protects you from a lifelong surcharge later. We'll help you get the timing right.

Think of Part D as your drug cost safety net.

You can:

  • Enroll in a standalone Part D plan if you have Original Medicare (with or without Medigap).

  • Or get Part D built into most Medicare Advantage plans.

What Part D Covers

  • A wide range of brand name and generic medications.

  • Drugs listed on each plan’s formulary (the official covered drug list).

  • Tiered cost structure: generics, preferred brands, non-preferred brands, and specialty drugs all have different copays.

What to Keep in Mind

  • Plans vary by carrier and region: The same drug may cost different amounts depending on the plan and pharmacy you use.

  • Premiums vary: Higher-income individuals may pay an extra surcharge (IRMAA).

  • Late enrollment penalty: If you go without “creditable coverage” when first eligible, you could pay a permanent penalty later.

  • Pharmacy choice matters: Some plans have preferred pharmacies where your costs are lower.

Cost Example

  • Generic (Tier 1): $0-$5 copay

  • Preferred brand (Tier 2): $20-$35 copay

  • Non-preferred brand (Tier 3): $45-90 copay, sometimes a percentage

  • Specialty (Tier 4/5): percentage of the drug cost

Bottom line: Choosing the right plan can save you hundreds. The wrong plan can cost you thousands.

Who Part D Works Best For

  • You take regular prescriptions and want predictable costs

  • You want protection from expensive brand-name or specialty drugs.

  • You want flexibility to pick a plan that matches your exact medications.

Not a fit if

  • You’re enrolled in a Medicare Advantage plan that already includes drug coverage.

  • You don’t take any prescriptions now and are willing to risk late penalties later (not recommended).

Next Steps.

Choosing the right Part D plan depends entirely on which medications you take and where you live. That’s why a one size fits all answer doesn’t work.
