See which PBMs cover a drug, tier placement, prior auth, and estimated copays.

Understanding formulary tiers

PBMs organize drugs into tiers that set your out-of-pocket cost. Tier placement isn't always clinical — rebate deals influence which drugs get preferred status.

Tier 1 — Preferred Generic · $0–15
Tier 2 — Preferred Brand · $25–50
Tier 3 — Non-Preferred · $50–100+
NC — Not Covered · Full cost
⚠️
A drug on Tier 1 at one PBM may be Tier 3 at another — hundreds of dollars per month difference for the same medication.
