Beginning with dates of service on and after November 1, 2018, we will expand pre-service clinical review requirements to include upper gastrointestinal (GI) endoscopy, also referred to as esophagogastroduodenoscopy (EGD). AIM Specialty Health® (AIM), a separate company, will administer this EGD review on our behalf.


EGD procedures will be reviewed against clinical guideline CG-MED-59 Upper Gastrointestinal Endoscopy, for clinical appropriateness and to help ensure care aligns with established evidence-based medicine. Please note, procedures performed in an inpatient or observation setting, or on an emergent basis will not be reviewed under CG-MED-59. Note that CG-MED-59 will be available on our website prior to its November 1, 2018 adoption.  


A complete list of EGD CPT codes requiring precertification is available on the AIM Surgical Procedures website.
