Predetermination (formerly called Prior Authorization)
Predetermination is a process BCBSMT uses to make coverage decisions in accordance with medical policy and group or member contracts for a service, supply, drug, or device used to diagnose or treat an illness or condition.
BCBSMT recommends predetermination for services if a provider is uncertain about coverage or if BCBSMT might not consider the service medically necessary.
Click here for a list of CPT, Revenue and HCPCS codes requiring special processing when submitted to BCBSMT. Examples of ‘special processing’ include “predetermination is recommended” (e.g., medical necessity criteria apply and medical records are generally necessary for processing) and codes denied experimental/investigational.

Advance Member Notification
Advance Member Notification (AMN) refers to the process in which a provider informs a member that a service is not likely to be considered for compensation by BCBSMT prior to the service being performed. Through the AMN process, the member is able to understand the financial implications of receiving the service, and the participating provider is able to alter the financial liability of a service that would be denied as not medically necessary. The AMN process only applies to professional services. This process does not apply to hospital-based services, skilled nursing facilities, or home health services.
