What is benefits verification?

Benefits verification determines how a patient's plan covers a specific procedure, for a specific rendering provider, at a specific place of service: whether the CPT code is covered, which deductible applies and how much remains, copay or coinsurance, visit limits, network tier and prior-authorization requirements. Applied to the provider's fee schedule, it produces the patient's estimated responsibility.

Benefits verification, verification of benefits (VOB) and benefits investigation all describe the same procedure-specific check. It needs more inputs than eligibility: the CPT code, the place of service and the provider's NPI, in addition to the patient's identifiers.

The output is also different. Eligibility ends in a status; benefits verification ends in a set of service-level facts and, with a fee schedule applied, a dollar figure the front desk can collect. That number is what patients mean when they ask what the visit will cost.
