2019 PriorityMedicare KeySM drug costs

The higher a drug's cost level or "tier," the higher the cost. In the chart below, you'll see what you'll pay for each drug tier for a 30-day supply at a preferred retail pharmacy and at a standard pharmacy, and for a 90-day supply through mail order (with free shipping). Costs may vary when your plan is provided by an employer.

Your drug copays/coinsurance

This is what you'll pay until you reach $3,820 in total drug costs for the year (the combined total of what you have paid plus what Priority Health has paid for your prescriptions).

Costs shown for tiers 3, 4 and 5 are what you'll pay after you meet the $125 Part D deductible. There is no deductible for drugs in tiers 1 or 2.

Then, once your out-of-pocket Part D drug costs reach $5,100, for the rest of the year you pay the greater of:

  • $3.40 for generic drugs
  • $8.50 for all other drugs
