Who submits written confirmation authorizing treatment to the provider?

The case manager typically submits written confirmation authorizing treatment to the provider. In the context of healthcare, a case manager plays a crucial role in coordinating care for patients, particularly those with complex medical needs or chronic conditions. They ensure that patients receive appropriate services and facilitate communication between the patient, healthcare providers, and insurance companies.

When treatment is required, the case manager assesses the patient's needs and often works with the insurance company to secure authorization for specific services or procedures. This authorization is necessary to ensure that the treatment will be covered by insurance and to avoid any unexpected out-of-pocket expenses for the patient.

While subscribers and enrollees are terms that refer to individuals who have health insurance coverage, they do not typically handle the authorization of treatments directly. A subscriber is the primary policyholder, and an enrollee is someone who is covered under that policy. The term "gatekeeper" usually refers to a managed care model where primary care providers oversee and coordinate treatment, but they do not necessarily submit written confirmations for treatment authorization. Therefore, the role of the case manager is pivotal in the authorization process, making it the correct answer.
