Final answer:
An assignment of benefits must be completed by a patient to allow the insurance company to pay the physician's office directly.
Step-by-step explanation:
For a patient to authorize payment directly from the insurance company to the physician's office, they must complete an assignment of benefits. This is a contractual agreement between the patient and the insurance company where the patient allows the insurer to pay the healthcare provider directly. Other options, such as coordination of benefits helps determine the primary payer when a patient has more than one insurance. A remittance advice is a notice sent by the insurance company to the healthcare provider with details of payment for services rendered. An explanation of benefits is a document sent to the patient explaining what costs were covered by insurance and what part the patient may be responsible for paying.
