What is "chargemaster"

n. (context US healthcare English) a comprehensive list maintained by a hospital of prices of goods and services it will bill to its patients and their respective health insurers.

In the United States, the chargemaster, also known as charge master, or charge description master (CDM), is a comprehensive listing of items billable to a hospital patient or a patient's health insurance provider. In practice, it usually contains highly inflated prices at several times that of actual costs to the hospital. The chargemaster typically serves as the starting point for negotiations with patients and health insurance providers of what amount of money will actually be paid to the hospital. It is described as "the central mechanism of the revenue cycle" of a hospital.
