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. For ease of reference, for many of the facility types, services, and products, the list includes the Place of Service (POS) code designated by the Centers for Medicare & Medicaid Services (CMS) or the Current Procedural Terminology (CPT) code designated by the American Medical Association. This listing of codes is not all-inclusive and is subject to change at any time. Any discrepancy or outdated code in this list does not control how the benefit is administered. If you have any questions about preauthorization, please call Member Services at (855) 979-5192.
