Effective August 1, 2021, AIM Specialty Health® (AIM), a separate company, will expand the AIM Rehabilitative program to perform medical necessity review of the initial evaluation service codes and requested site of service for physical, occupational and speech therapy procedures for Anthem Blue Cross and Blue Shield (Anthem”) fully insured members, as further outlined below. 


AIM will continue to manage Physical Therapy (PT), Occupational Therapy (OT) and Speech Therapy (ST) medical necessity reviews and will require pre-certification for all outpatient facility and office-based rehabilitative and habilitative services.  Prior authorization will now also be required for the initial evaluation service codes, unless otherwise prohibited, to alert the provider of the site of care program and ensure the member is receiving care at the appropriate site of service early in the process.  After the evaluation, ongoing services will be subject to site of care review and require prior authorization.  AIM will use the following Anthem Blue Cross and Blue Shield (“Anthem”) Clinical UM Guidelines: CG-REHAB-10 Site of Care: Outpatient Physical Therapy, Occupational Therapy, and Speech-Language Pathology Services. The clinical criteria to be used for these reviews can be found on Anthem’s Clinical UM Guidelines pagePlease note, this does not apply to procedures performed in an inpatient or observation setting, or on an emergent basis, members currently in an episode of care at the start of the program, services with diagnosis of autism, and members ages.


A complete list of CPT codes requiring prior authorization for the AIM Rehabilitation program is available on the AIM Rehabilitation microsite.  To determine if prior authorization is needed for an Anthem member on or after August 1, 2021, Providers can contact the Anthem Provider Services phone number on the back of the member’s ID card for benefit information.  They will be informed whether the AIM Rehabilitation program applies.  AIM will also have a file upload from the health plan of the in-scope membership and will not provide pre-certification for members who are out of scope.  If providers use the Interactive Care Reviewer (ICR) tool on the Availity Portal to pre-certify an outpatient rehabilitative or habilitative service, ICR will produce a message referring the provider to AIM. (Note: ICR cannot accept pre-certification requests for services administered by AIM.)

All FI members currently participating in the AIM Rehabilitative program are included. Medicaid members will be included in a separate communication. The following groups are excluded:  Medicare Advantage, Medicaid, Medicare, Medicare supplement, MA EGR, Federal Employee Program® (FEP®).
