How to request retroactive prior authorization for commercial PPO Radiology Management Program

Providers have up to 90 days past the date of service to request retro prior authorization through AIM Specialty Health^SM for Blue Cross Blue Shield of Michigan commercial PPO members participating in our Radiology Management Program. Although 90 days is allowed, we encourage providers to obtain prior authorization before administering services.

Prior authorization requests are initiated through the AIM online portal and by phone. AIM completes approximately 90 percent of authorizations within 48 hours of the request.

How to submit a request

• Retro prior authorization requests
• Only by phone at 1-800-728-8008
• All other requests
• Online at AIMSpecialtyhealth.com

We’ll consider requests older than 90 days but less than 180 days from the date of service for a coordination of benefits decision. Documentation of the other carriers’ remittance must be submitted. For these considerations, call our provider service phone numbers:
