Checking eligibility and/or benefit information and/or obtaining prior authorization is not a guarantee of payment. Benefits will be determined once a claim is received and will be based upon, among other things, the member’s eligibility and the terms of the member’s certificate of coverage, including, but not limited to, exclusions and limitations applicable on the date services were rendered. Certain employer groups may require prior authorization or pre-notification through other vendors. If you have any questions, call the number on the member's ID card. 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.
