IMPORTANT REMINDER

 

We develop Medical Policies to provide guidance to Members and Providers.  This Medical Policy relates only to the services or supplies described in it.  The existence of a Medical Policy is not an authorization, certification, explanation of benefits or a contract for the service (or supply) that is referenced in the Medical Policy.  For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed.  If there is a conflict between the medical policy and a health plan or government program (e.g., TennCare), the express terms of the health plan or government program will govern.
