Drug Formulary

処方薬リスト (shohōyaku risuto)

A drug formulary is a list of prescription medications covered by a health insurance plan. Formularies are organized into tiers, typically ranging from Tier 1 (generic, lowest cost) to Tier 4 or 5 (specialty drugs, highest cost). Drugs not on the formulary require an exception or prior authorization. Formularies change annually and sometimes mid-year; patients should verify their medications are covered before enrolling in a plan or filling a new prescription. Generic substitutes are often available for off-formulary drugs.

Checking the formulary before selecting a plan is especially important for patients who take regular prescription medications.
