Chargemaster
Updated September 30, 2026
Definition
A hospital's master list of full prices for every item and service it bills. These prices come before any discounts, so what you pay is often less.
A chargemaster is a hospital's master price list. It has a code, a description, and a full price for each item and service, from a room charge to a single pill. Federal rules call these prices gross charges, meaning the price before any discounts.
Many people pay less than these prices. Health plans usually pay rates they negotiated with the hospital. People paying on their own may get a cash price or financial assistance. Since January 1, 2021, hospitals have had to post their prices online for all items and services.
For example, say your itemized bill lists an MRI at $3,200, the chargemaster price. Your plan's allowed amount may be closer to $900. If you're paying on your own, ask for the cash price and any discounts. Our guide on how to get an itemized bill shows how to see every line.
