Our automated preauthorization tool – AerialTM iExchange® (iExchange) – supports direct submission and provides online approval of benefits for inpatient admissions, as well as select outpatient, and pharmacy services 24 hours a day, seven days a week – with the exception of every third Sunday of the month when the system will be unavailable from 11 a.m. to 3 p.m. (CT). iExchange is accessible to physicians, professional providers and facilities contracted with BCBSMT.

New User Setup

You will need a User ID, password and iExchange ID to gain access to the tool.

  • If you are a new employee in an office that already uses iExchange, contact your office administrator for a new username.
  • If your office is new to iExchange, you will need to set up an initial administrator account.
  • Availity or BCBSMT Secure Provider Portal users may access iExchange through these options.
  • For non Availity or BCBSMT Secure Provider Portal users must complete and submit the online enrollment form. To set up a new account, you must be a network physician, professional provider or facility within Montana.

New Account Management

Enrollment confirmation will be sent via email within 10 business days. The assigned User ID is for your office administrator who will also be able to create additional usernames for new staff members. The unique iExchange ID is your office account number — it is the same for all users in your office.

  • You will receive a temporary password, which must be changed upon receipt.
  • If you forget your password or it has been compromised, use the Forgot Password option on the iExchange Provider login page . Or, ask your office administrator to reset your password for you.
  • If you are the iExchange office administrator and you need your password reset, complete and submit the iExchange Password Reset Form. All passwords must be changed every 30 days.

Using iExchange

The Provider login  can be added to your favorites. Transaction requests include inpatient admission requests and extensions, treatment searches, provider/member searches and select outpatient service requests and extensions.

  • To search by member ID, key the member ID exactly as it appears on the ID card. Name and date of birth search options also are available.
  • Required Data - All fields should be completed for each transaction unless marked "optional." Short lists can be created by the administrative users for commonly used provider ID numbers, diagnoses and procedure codes.
