Introducing A New Preauthorization Submission Tool Via Availity® Provider Portal

Dec. 25, 2019

Blue Cross and Blue Shield of Montana (BCBSMT) is excited to introduce a brand-new online preauthorization application via the Availity Portal, called Authorizations (HIPAA-standard 278 transaction). This new and more convenient functionality will be available to providers as of Jan. 30, 2020, making it faster and easier to submit and receive confirmation from BCBSMT. For Federal Employee Program®; (FEP®), providers should continue to use their current preauthorization process until this the new application becomes available in the near future.

What does this mean?

BCBSMT’s current electronic preauthorization tool, iExchange®, will be deactivated on April 15, 2020, and all electronic preauthorization requests and referrals should be submitted using this new capability. This includes inpatient admissions, select outpatient services, behavioral health services and referral requests handled by BCBSMT.

The process of submitting preauthorization requests to eviCore is not changing.

Medical and surgical predetermination of benefits requests should be submitted via fax or mail by using the appropriate Predetermination Request Form, along with the pertinent medical documentation. This form is located in the Forms section on our Provider website.

What should you do?

During the transition period, providers should migrate from iExchange to the new five-step Availity Authorization application. Providers not yet registered with Availity can sign up today at Availity, at no charge. For registration assistance call Client Services at 800-282-4548.

Submitting online preauthorization requests using Availity’s Authorizations application is easy and consists of only five steps:

  1. Log into
  2. Select Patient Registration menu option, choose Authorizations & Referrals, then Authorizations*
  3. Select Payer BCBSMT, then choose your organization
  4. Select Inpatient Authorization or Outpatient Authorization
  5. Review and submit your authorization

This new online option will increase administrative efficiencies for your organization by also allowing providers to:

  • access and verify status of requests
  • upload clinical medical records
  • edit and/or extend requests
  • obtain printable confirmation number for your records
