CPT® Code 27734

Epiphyseal arrest, also known as epiphysiodesis, is a surgical procedure aimed at addressing discrepancies in bone length, particularly between the lower legs or between the tibia and fibula. The term "epiphysis" refers to the growth plate, which is a critical area of developing bone tissue that influences the length and shape of the bone as a child grows. In this procedure, a surgical incision is made over the distal aspect of the tibia and/or fibula, allowing access to the underlying structures. Careful dissection of the soft tissues is performed to protect vital blood vessels and nerves in the area. Once the distal tibia and/or fibula are adequately exposed, various devices such as Blount staples, transphyseal screws, or a plate and screw device are strategically placed within the epiphysis. These devices serve to temporarily halt the growth of the bone, thereby correcting the length discrepancy. It is important to note that specific CPT® codes are designated for different scenarios: CPT® Code 27730 is used for epiphyseal arrest of the distal tibia, CPT® Code 27732 is for the distal fibula, and CPT® Code 27734 is applicable when the procedure involves both the distal tibia and fibula.
