Summary
Aetna's updated Clinical Policy Bulletin 0255 (reviewed May 13, 2026) clarifies medical necessity criteria for inpatient hospital admission on the day(s) prior to surgery. The policy establishes specific clinical scenarios where preoperative hospitalization is covered, including pediatric cardiac procedures requiring hydration, high-risk bowel prep cases, brittle diabetes requiring glucose monitoring, fiducial placement for brain surgery, concurrent medical problems requiring inpatient treatment before major surgery, unstable cardiac patients undergoing open heart procedures, and cases requiring medications/fluids unavailable in outpatient settings. This requires billing teams to ensure prior authorization requests include documented medical necessity aligned with these specific criteria.
Action Required
By May 26, 2026: Billing team must update preoperative admission authorization protocols to require provider documentation demonstrating medical necessity per the seven specific clinical criteria outlined in CPB 0255. When processing claims for inpatient preop days associated with thoracotomy (32096-32160), cardiac surgery (33016-33980), laparotomy (47015, 49000-49002), craniotomy (61304-61576), stereotactic radiosurgery (61796-61800), cardiac catheterization (93451-93454), or fiducial placement (A4648, C1739), verify that submitted documentation addresses: (1) specific patient risk factors, (2) why intervention could not be provided outpatient or via home health, and (3) how the inpatient admission reduces operative risk. Update prior authorization request templates to include mandatory fields for these documentation elements. Train billing and authorization staff on the seven covered scenarios. Failure to align authorizations with these criteria may result in claim denials for medically unnecessary preoperative hospitalization.
