Authorization to Participate in Medical Plan is a legally binding document that allows a person to participate in a health care plan or program. It is typically used by employers who provide their employees with health insurance, as well as by individuals who purchase coverage in the individual market. The authorization contains information about the plan, including the type of coverage, the premium, co-payments and deductibles, and any other terms or conditions that may apply. It also acknowledges the participant’s agreement to abide by the terms of the plan. There are two types of Authorization to Participate in Medical Plan: active authorization and passive authorization. Active authorization requires the participant to sign the authorization form and submit it to the plan administrator for approval. Passive authorization occurs when a person is automatically enrolled in a plan, such as when an employee is automatically enrolled in an employer-sponsored health plan. In this case, the participant does not need to sign an authorization form but is instead enrolled in the plan without providing written consent.
