Rebate

A discount paid by a drug manufacturer to an insurer or PBM after a sale, reducing the effective price below the list price.

How It Works

Rebates are the hidden discounts that make drug pricing so opaque. Manufacturers pay rebates to PBMs and insurers in exchange for favorable formulary placement — putting the drug on a preferred tier so more patients use it. Rebates can range from 10% to over 70% of a drug's list price, but they don't always reduce what patients pay at the pharmacy counter. A drug with a $500 list price and a 50% rebate effectively costs the insurer $250, but a patient in the deductible phase may still pay the full $500. The Inflation Reduction Act is beginning to change this by requiring that insulin rebates flow to patients at the point of sale.
