What term is used by the Federal Employee Anthem Plan for obtaining written approval of a proposed treatment?

The term used by the Federal Employee Anthem Plan for obtaining written approval of a proposed treatment is "Authorization." This term specifically refers to the formal approval process that healthcare providers and patients must go through to ensure that a proposed treatment, service, or medication is covered under the insurance plan before the service is rendered. Authorization is a key component of prior authorization and is essential for managing healthcare costs and ensuring that services are medically necessary according to the plan's guidelines.

The other terms mentioned do not accurately describe this process. "Case Management Approval" generally refers to a broader process wherein a case manager coordinates care for patients with complex conditions but does not specifically pertain to the approval of individual treatments. "Chiropractor" is a type of healthcare provider and not related to the authorization process. "Commercial Policy" typically refers to a type of insurance coverage offered in the private sector but does not denote the specific action of obtaining approval for treatments within the context of the Federal Employee Anthem Plan.
