Abdominoplasty, Suction Lipectomy, and Ventral Hernia Repair (CPB 0211, reviewed 2026-08-18)
Aetna considers panniculectomy or apronectomy medically necessary when the panniculus hangs below the pubis on high-quality color photographs, the medical records show chronic intertrigo that recurs over 3 months or stays refractory to 3 months of appropriate therapy, and weights have been stable for the most recent 3 months; for bariatric patients, at least 12 months must have elapsed since the bariatric plateau. Repair of a true incisional or ventral hernia is considered medically necessary, and component separation is considered a medically necessary adjunct when a ventral hernia is larger than 10 cm in any direction, involves loss of domain, is 7 to 10 cm wide with a width to rectus abdominis width ratio of 2 or more, is complex with tissue loss, or follows prior failed repairs. Liposuction, lipectomy and excision of excessive skin are considered medically necessary for lipedema of the extremities after pain and disability persist despite 3 months or more of conservative management, and suction lipectomy of the trunk is considered medically necessary for lipedema when the specified pain, functional impairment and conservative-treatment criteria are met. Abdominoplasty, lipoabdominoplasty, suction lipectomy for indications other than lipedema and lymphedema, and panniculectomy that does not meet the criteria are considered cosmetic, repair of diastasis recti is considered not medically necessary, and several ventral hernia techniques, including enhanced-view totally extra-peritoneal repair, TAPPRA and peritoneal flap hernioplasty, are considered experimental, investigational or unproven.

Virtual delivery by real-time audio and video (excluding audio-only) is considered medically necessary when the telehealth program and member criteria are met, but hospital outpatient departments are not eligible for virtual telehealth services. Intensive cardiac rehabilitation is considered experimental, investigational or unproven for diabetes, hyperlipidemia, prostate cancer, metabolic syndrome and all other indications where effectiveness has not been established.
