Prescription Drug Coverage: Formularies, Tiers, and Costs

Prescription drug coverage organizes medications into tiers — generic drugs on Tier 1 cost the least ($5-15), preferred brands on Tier 2 cost more ($25-50), and specialty drugs on higher tiers may require coinsurance of 25-50%. Your plan's formulary lists which drugs are covered, and medications not on the formulary may require prior authorization or an exception request.
