Answer: You should report 27698 (Repair, secondary, disrupted ligament, ankle, collateral [e.g., Watson-Jones procedure]) for this surgery.

Orthopedic surgeons perform the Chrisman-Snook operation to replace damaged ligaments on the outer (lateral) side of the ankle. The surgeon brings the peroneous brevis graft through the fibula from anterior to posterior to reconstruct the anterior talofibular ligament. He then brings it posteriorly and inferiorly to the calcaneus to reconstruct the calcaneofibular ligament.
