Medicare Part D Tier Costs

Estimated reading time: 3 minutes

Read this article to discover the differences in Medicare Part D tier costs. Medicare categories your medications into one of the following five drug tiers:

• 1st tier preferred generic drugs with the lowest copays
• 2nd tier non-preferred generic drugs with higher copays
• 3rd tier preferred brand name drugs
• 4th tier non-preferred brand name drugs
• 5th tier specialty drugs

You can determine whether your prescriptions are generic or brand name by looking at your plan’s drug formulary.

Drug Formulary Costs

According to GoodRx, your medication formulary “is a list of generic and brand name prescription drugs covered by your health plan.” When you use the drugs in your formulary, you will pay less for prescriptions. However, Medicare.gov says, “if you use a drug that isn’t on your plan’s drug list, you’ll have to pay full price instead of a copayment or coinsurance.” 

In most cases, tier 1 and 2 generic drugs will cost less than tier 3 and 4 brand name drugs. The price you pay for both generic and brand name prescriptions will change depending on your coverage stage. You can learn more about the four stages of drug coverage and costs in 2021.

In the MedicareBob video, Robert Bache says, “most drug plans cover tier-1 medications for $1 or $2, and tier-2 drugs for $3 to $5.” Furthermore, the price you pay for tier-1 and tier-2 prescriptions do not apply towards Part D deductible. However, Part D deductible does apply towards tiers 3, 4, and 5.
