CPT® Code 27696

The procedure described by CPT® Code 27696 involves the primary repair of disrupted ligaments in the ankle, specifically addressing both collateral ligaments. The ankle joint is supported by three groups of ligaments: the deltoid or medial collateral ligament, which provides medial stability; the three lateral collateral ligaments (anterior talofibular, posterior talofibular, and calcaneofibular ligaments), which offer lateral support; and the syndesmotic ligaments, which help maintain the alignment of the ankle. When any of these ligaments are disrupted, it can lead to instability in the ankle joint, resulting in pain and impaired function. This code is specifically used when both collateral groups of ligaments are affected and require surgical intervention. The procedure typically involves making an incision over the affected area, exposing the damaged ligaments, and performing necessary debridement of any injured tissue. The ligaments are then repaired using sutures, or if they have detached from the bone, they may be reattached using a bone screw. It is important to note that CPT® Code 27696 is designated for the primary repair of these ligaments, distinguishing it from other codes that may apply to different scenarios or types of ligament disruptions.
