Ankle Distraction Procedure
A patient with post-traumatic arthritis of the left ankle was admitted for distraction arthroplasty. An ankle distraction frame and ring were applied to the distal third of the tibia and stabilized with pins. A transmalleolar wire was placed through the talus to identify the center of rotation and guide the building of lateral and medial distraction hinges. A foot ring was attached to hinges and stabilized to the foot with wires through the calcaneus and talar neck. The wires were tensioned and an anterior locking rod was placed to hold the ankle in neutral position. Distraction was placed across the ankle at 4mm and bone marrow aspirate and stem cells were inserted into the ankle joint. What is the ICD-10-PCS code for distraction arthroplasty of the ankle with application of an external hinged fixator? Is the procedure a distraction of the ankle joint or tarsal joint? ...
