Final answer:
An assignment of benefits is a binding arrangement where an insured requests that payments under their health plan be made directly to a designated person or facility. It ensures that the reimbursements go directly to the healthcare provider without the need for reimbursement.
Step-by-step explanation:
A binding arrangement under which an insured requests that payments under their health plan be made directly to a person or facility that they designate (such as a doctor or hospital) is called an Assignment of benefits.
