Final answer:
The dentist can use assignment of benefits after the patient or subscriber signs the claim form, allowing the dentist to be paid directly by the insurance company.
Step-by-step explanation:
Once the patient or subscriber signs a claim form, the dentist can use A. Assignment of benefits. This allows the dentist to receive payment directly from the patient's insurance company for the services rendered. An assignment of benefits is a document that transfers the insurance claims rights of the patient to the dentist. This means that the insurance company pays the dentist directly for the cost of dental treatment, rather than the patient paying upfront and getting reimbursed by the insurance company later. The release of information may also be needed in such cases, as it authorizes the dentist to obtain and disclose medical information required by the insurance company to process the claim. However, the signature itself is not needed once it is on file, and the claim form has been signed initially.
