Reminder: Verify Procedure Code Preauthorization Requirements Online

Jul. 23, 2019

In the December  2018, we announced a new online capability that allows providers to verify preauthorization requirements for specific Current Procedural Terminology (CPT) or Healthcare Common Procedure Coding System (HCPCS) codes via an eligibility and benefits inquiry in the Availity® Provider Portal. Since implementation many updates have been made to improve articulation.


To ensure code-specific preauthorization requirements are returned online, a valid CPT/HCPCS code(s)* and associated place of service must be submitted in the eligibility and benefit inquiry (270). If a CPT/HCPCS code is not entered, then the place of service and benefit/service type are required. If a benefit/service type is not selected, the place of service and at least one CPT/HCPCS code is required. Additionally, no benefit or preauthorization information will return for the benefit/service type if one is not selected.

*Providers may enter up to eight procedure codes in the inquiry.

The eligibility and benefit inquiry response (271) displays preauthorization requirements in the Pre-Authorization Info tab. In some instances, providers may receive a “Auth Info Unknown” response for the requested benefit/service type. If preauthorization is required or unknown, contact information for completing the request and other important details are included.

As a reminder, the CPT/HCPCS code inquiry option is for preauthorization determination only and is not a code-specific quote of benefits.


Online code-specific preauthorization information is not yet available for the following Blue Cross and Blue Shield of Montana (BCBSMT) members:

  • Federal Employee Program® (FEP®)
  • Blue Cross Medicare Advantage (HMO)SM and Blue Cross Medicare Advantage (PPO)SM

Checking eligibility and/or benefit information and/or the fact that a service has been preauthorized 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 or contract of coverage applicable on the date services were rendered. If you have any questions, please call the number on the member’s ID card.
