Prior Authorization Update - Pharmacy Medical Oncology

Jun. 21, 2021

What’s Changing: Blue Cross and Blue Shield of Montana (BCBSMT) is changing prior authorization requirements for specialty drugs used for oncologic application.

Starting October 11, 2021, AIM Specialty Health® (AIM), rather than BCBSMT, will manage prior authorization requests and post service medical necessity reviews for drugs in the Pharmacy Medical Oncology care category for some members.

What’s Not Changing: Healthy Montana Kids (HMK) medical drug applications will continue to be managed by BCBSMT.

Note: AIM will review requests for oncology drugs that are supported by an oncology diagnosis. If the drug requested is not associated with an oncology diagnosis, it will be reviewed by BCBSMT.

Important Reminder: Always check eligibility and benefits first through the Availity® Provider Portal or your preferred vendor portal, prior to rendering services. This step will confirm prior authorization requirements and utilization management vendors, if applicable.

Keep in mind these key dates and scenarios as we transition to AIM:

  • Authorizations initiated with BCBSMT will remain active with BCBSMT until the request expires, including dates before or after October 11, 2021.
  • Contact BCBSMT to extend an active authorization for dates of service prior to October 11, 2021.
  • Contact AIM via the ProviderPortal  to extend an active authorization for dates of service on or after October 11, 2021.
  • Contact AIM for all authorizations initiated on and after October 11, 2021. Please use the AIM ProviderPortal for any new requests.
  • Predeterminations will no longer be offered for the Medical Oncology drug care category. All requests will be processed as a prior authorization.
  • AIM’s ProviderPortal  and call center will be begin accepting prior authorization requests on Sep. 27, 2021 for dates of service on or after October 11, 2021.
  • Do not submit prior authorization requests for Medical Oncology drug codes to BCBSMT for dates of service on or after October 11, 2021 (Exception: HMK).
  • Continue to submit prior authorization requests to BCBSMT through October 10, 2021, for dates of service before October 11, 2021.
