What is Medicare Part D Prescription Drug Coverage?
Since Original Medicare and most Supplement (Medigap) plans don’t include drug coverage, Medicare Part D helps cover your prescription costs.
You have two ways to get Medicare drug coverage:
- If you have Original Medicare (with or without a Medigap plan), you can add a standalone Part D plan.
- If you have a Medicare Advantage plan, drug coverage is often built into the plan (check with your provider to confirm).

How Does Medicare Part D Work in Nebraska?
Each Part D plan has its own list of covered medications, called a formulary, organized into tiers based on cost.
Here’s a quick breakdown:
- Tier 1: Generic, lowest co-pay
- Tier 2: Preferred brand-name drugs
- Tier 3: Non-preferred brand drugs
- Tier 4+: Specialty drugs with higher costs
Each plan may charge different premiums and co-pays depending on its formulary. Plans can change these formularies annually, so it’s important to review your plan each year.
The best way to find the right plan is to speak with a local licensed Medicare agent who can compare options based on the medications you take.
Am I Eligible for Medicare Part D?
Medicare prescription drug plan eligibility
If you have Medicare Part A or B, you’re eligible to enroll in a Part D plan—just make sure to do so during a valid enrollment window.
Avoid the Late Enrollment Penalty
If you don’t enroll in a Part D plan when first eligible and go 63+ days without creditable drug coverage, you may pay a lifetime penalty:
🔷 If you wait 63+ days after becoming eligible for Medicare without creditable drug coverage, you may owe a permanent monthly penalty — 1% of the national base premium for every month you delayed.
Even if you’re not currently taking prescriptions, consider enrolling in a low-cost plan now to avoid penalties later.
