Prescription Coverage Basics: Formularies, Tiers, Generics

Updated 2025-09-16

Formulary and tiers

Your plan’s formulary lists covered drugs by tier (generic, preferred brand, non‑preferred brand, specialty). Costs vary by tier and whether the drug requires prior authorization or step therapy.

How we help

We run your medication list through each plan’s formulary, check pharmacy networks, and estimate monthly costs so there are no surprises.

Need help deciding? True North Roots can compare plans, estimate your subsidy, and enroll you at no cost.
