Usual, Customary, and Reasonable (UCR)
Dental RCM Glossary
Fee benchmarks used by dental insurers to determine the maximum reimbursement for a specific procedure in a geographic area.
Usual, Customary, and Reasonable refers to the fee benchmarks that dental insurance companies use to establish reimbursement levels for covered procedures. The three components each represent a different reference point. Usual refers to the fee a specific dentist typically charges for a given service. Customary refers to the range of fees charged by dentists in the same geographic area for the same service. Reasonable accounts for the complexity or unusual circumstances of a specific case that may justify a fee outside the customary range. Insurance carriers compile these data points, often sourcing from databases such as FAIR Health, to establish percentile-based fee schedules that cap reimbursement for each procedure code within a defined geographic region.
UCR fee schedules are most directly relevant to out-of-network reimbursement and indemnity plan payments, where there is no contracted fee between the provider and the carrier. When a patient visits an out-of-network provider, the carrier typically reimburses based on a specific percentile of the UCR data for the procedure and geographic area, commonly the 80th or 90th percentile. If the provider's charge exceeds the UCR-based allowed amount, the patient may be responsible for the difference in addition to their normal cost-sharing. For in-network providers, the contracted fee schedule supersedes UCR rates, though UCR data often serves as a starting point for fee schedule negotiations between carriers and providers.
For dental practice administrators, UCR data is an essential tool for fee schedule strategy. A practice's standard fees should be set at or above the highest UCR percentile used by any of its payers to ensure maximum reimbursement from all carriers, including out-of-network plans. Practices that set fees significantly below prevailing UCR rates forfeit reimbursement they are entitled to receive. Conversely, practices should be aware that fees set far above UCR levels may create substantial balance-billing amounts for out-of-network patients, which can affect patient acquisition and satisfaction. Annual review of regional UCR data allows practices to adjust their fee schedules in alignment with market conditions and payer reimbursement trends.
Why It Matters for Dental Practices
UCR rates serve as the reimbursement ceiling for out-of-network claims and the benchmark for setting practice fees. Practices that set fees without reference to UCR data risk under-billing or creating excessive patient balance-billing situations.
Example
The 90th percentile UCR for a crown (D2740) in a metropolitan area is $1,250. A practice sets its fee at $1,300 to exceed all payer maximums. An out-of-network plan reimburses at the 80th percentile ($1,100), leaving the patient responsible for the $200 difference plus coinsurance.
