CPT® Code 27612

The procedure described by CPT® Code 27612 refers to an arthrotomy involving a posterior capsular release of the ankle, which may also include the lengthening of the Achilles tendon. This surgical intervention is typically indicated when the ligaments surrounding the ankle joint are excessively tight or when there is a congenital deformity, such as clubfoot, that affects the normal function and alignment of the foot and ankle. The joint capsule, which is a fibrous structure that encases the joint and provides stability, may need to be incised to alleviate tension and improve mobility. During the procedure, a posterior approach is utilized, allowing the surgeon to carefully dissect the surrounding tissues to access the joint capsule. Once exposed, the posterior ligaments and the joint capsule are incised, which facilitates an increase in the range of motion and addresses any existing malformations. Additionally, the Achilles tendon may be lengthened through techniques such as Z-plasty or longitudinal incisions, which are designed to enhance flexibility and function. After the surgical intervention, the foot is typically immobilized in a cast to ensure it remains in a more anatomically correct position, aiding in the healing process and preserving the length of the ligaments and Achilles tendon.
