Usual, Customary, and Reasonable (UCR)
Also called: UCR
Usual, customary, and reasonable is a benchmark plans use to decide how much to pay for a service, especially out-of-network, based on typical charges in the area. If a provider bills above the UCR amount, the plan may pay only up to that figure and leave you responsible for the rest. Disputes over how a UCR rate was calculated can be a basis for appeal.
