How often do health insurers usually require services to be re-authorized?

Health insurers typically require services to be re-authorized every 6 to 12 months, depending on factors such as the specific insurer's policies and the type of service being provided. This timeframe allows insurers to regularly review the necessity and appropriateness of ongoing treatment or services, ensuring compliance with medical necessity guidelines and adapting to any changes in a patient’s health status or treatment plan.

For example, chronic conditions may require more frequent reviews, while some treatments or procedures may adhere to a longer authorization period. This practice helps to ensure that resources are allocated efficiently and that patients receive the most current and effective care possible. Regular re-authorization also helps insurers manage costs and assess the effectiveness of services provided, making it a key component of managed care.
