Site-of-service precertification requirements


We implemented site-of-service precertification requirements for certain procedures effective December 1, 2021.


  • We do not require precertification for certain services performed in an ambulatory surgical facility or an office.
  • We do require precertification for certain procedures performed in an outpatient hospital setting.

View our lists and search by CPT code


You can view our precertification lists and search by CPT code on our Precertification Lists page. Or go to our Availity provider portal* to get a list of procedure codes that require precertification under this policy. Once there, go to Aetna Payer Space > Resources > Site of Service Outpatient Surgical Procedure list.


We need the site of service when you call for precertification


When you contact Aetna® for precertification, you must provide the site where the service is to be performed. Failure to do so may result in denied services.
