Anthem Blue Cross and Blue Shield (Anthem) is committed to being a valued health care partner in identifying ways to achieve better health outcomes, lower costs and deliver access to a better healthcare experience for consumers.


Effective with dates of service on or after June 1, 2020, members with commercial plans covered by Anthem will require a medical necessity review of the hospital outpatient level of care for certain upper endoscopy and colonoscopy procedures. The clinical guideline, Level of Care: Hospital-Based Ambulatory Surgical Procedures and Endoscopic Services, CG-SURG-52, will apply to the review process. The review will be administered by AIM Specialty Health® (AIM).


AIM will evaluate the clinical information in the request against CG-SURG-52, to determine if the hospital-based outpatient setting is the appropriate level of care for the endoscopy service. Your office may contact AIM to request a peer-to-peer discussion before or after the determination.


The level of care medical necessity review only applies to procedures performed in an outpatient hospital setting. This does not apply to requests for review of endoscopy performed in a non-hospital setting or as part of an inpatient stay. Reviews also do not apply when Anthem is the secondary payer.
