Summary
This policy defines coverage for vertical expandable prosthetic titanium rib (VEPTR) devices, considering them medically necessary only for progressive thoracic insufficiency syndrome in children 6 months to skeletal maturity, but investigational for scoliosis without thoracic insufficiency. The policy was updated in 2024 to include the new RESPONSE Rib and Pelvic System as substantially equivalent to VEPTR devices.
Action Required
Immediately: Billing team must verify thoracic insufficiency syndrome diagnosis is documented before billing unlisted procedure codes 20999 or 21899 for VEPTR or RESPONSE device implantation. Ensure preoperative evaluations include pediatric orthopedist, pulmonologist, and thoracic surgeon input. Claims for scoliosis treatment without thoracic insufficiency syndrome will be denied as investigational.
