Orthopedic surgery
About 27479: Distal tibial growth plate arrest
Reports surgical arrest of the distal tibial growth plate to guide leg growth, commonly for a planned correction of limb-length difference.
An orthopedic surgeon uses this procedure to stop growth at the distal tibial physis, near the ankle. It may be selected as part of a growth-guidance plan for a child or adolescent with a leg-length difference, when remaining growth is expected to help bring limb lengths closer. The code identifies the distal tibia; growth arrest at another physis or at multiple sites is coded according to the site and extent performed.
Report the procedure when the operative record supports arrest of the distal tibial physis, with the side, site, and method documented. This major surgery has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When bilateral procedures are performed, modifier 50 is paid at 150%. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures at 50%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

Does the global period include related postoperative care?
Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How is a bilateral procedure handled?
When the procedure is performed bilaterally, modifier 50 applies and CMS pays at 150%.
