Appendix C: Services and Products That Require Preauthorization 

Preauthorization is a determination of medical necessity before a service is performed or a product is provided. It is not a guarantee of payment. At the time the member’s claims are submitted, they will be reviewed in accordance with the terms of the Alliance Coal Health Plan. The final determination of whether services or products are eligible expenses is subject to all conditions, exclusions, and limitations of the Plan.

This appendix provides a detailed listing of services and products for which preauthorization is required to avoid a benefit penalty. This list will be updated periodically. If you have any questions about preauthorization, please call Member Services at (855) 979-5192.
