For members enrolled in Anthem commercial plans with dates of service on or after December 1, 2020, the site of care* medical necessity review will expand to additional surgical procedures performed in an outpatient hospital setting. Clinical guideline CG-SURG-52, Site of Care**: Hospital-Based Ambulatory Surgical Procedures and Endoscopic Services will apply to the review process. AIM Specialty Health® (AIM) will administer the review.


The site of care review will apply to a wide range of surgical procedures, including but not limited to, the following specialty categories:


  • Auditory system
  • Digestive/Gastrointestinal system
  • Eye/ocular adnexa system
  • Female genital system
  • Hemic and lymphatic system
  • Integumentary system
  • Male genital system
  • Musculoskeletal system
  • Nervous system
  • Respiratory system
  • Urinary system


For a complete list of procedures, Frequently Asked Questions and additional information, visit aimproviders.com/surgicalprocedures/resources


AIM will use CG-SURG-52 to evaluate the clinical information in the request and determine if the procedure requested requires a hospital-based outpatient setting. Providers may contact AIM to request a peer-to-peer discussion before or after the review is complete.


The site of care review only applies to procedures performed in an outpatient hospital setting. The site of care review does not apply to procedures performed in a non-hospital setting or as part of an inpatient stay, nor when Anthem is the secondary payer.

* In some plans, ‘level of care,’ ‘site of service’ or another term such as ‘setting’ or ‘place of service’ may be the term used in benefit plans, provider contracts, or other materials instead of or in addition to “site of care” and, in some plans, these terms may be used interchangeably.  For simplicity, we will hereafter use ‘site of care’.


** At the time of this notice, Anthem is in the process of retitling this guideline to use site of care in place of level of care.
