** Prior authorization determines whether the proposed service or treatment meets the definition of medical necessity under the applicable benefit plan. Prior authorization of a service is not a guarantee of payment of benefits. Payment of benefits is subject to several factors, including, but not limited to, eligibility at the time of service, payment of premiums/contributions, amounts allowable for services, supporting medical documentation, and other terms, conditions, limitations, and exclusions set forth in the member's policy certificate and/or benefits booklet and or summary plan description. Regardless of any Prior authorization or benefit determination, the final decision regarding any treatment or service is between the patient and the health care provider.
