Commonly charged fees for health services in a certain area. The use of fee screens to determine the lowest value of provider reimbursement based on: (1) the provider’s usual charge for a given procedure, (2) the amount customarily charged for the service by other providers in the area (often defined as a specific percentile of all charges in the community), and (3) the reasonable cost of services for a given patient after medical review of the case. Most health plans provide reimbursement for usual and customary charges, although no universal formula has been established for these rates.
