The procedure for dealing with Leg Length Discrepancy (LLD) is termed Osteoplasty. Depending on where the discrepancy is located (thigh, lower leg, or both) determines whether the bones are lengthened or shortened. Lengthening is more commonly done than shortening. For the Thigh/Femur, 22465 is for Osteoplasty of the femur with shortening, and 22466 is for femoral lengthening. For the Lower Leg/Tibia and Fibula, 27715 covers both shortening and lengthening. These apply basically to the boney structures. The soft tissues (muscle, tendons, nerves, and blood vessels) are not always treated surgically. In lengthening procedures, the process of gradually lengthening the bone is so slow that these tissue are generally allowed to stretch out and lengthen along with the bone. All of them have to be monitored very closely, particularly the nerves and vessels, during this process, and if problems arise for nerves or circulation, then the process has to be slowed even more, or stopped completely if the viability of the lower leg and foot are threatened. Tendon lengthening procedures may have to be done at some point along the way, maybe at the beginning, but more likely if they don't seem to be lengthening well as the bone is lengthened. The codes for tendon or muscle lengthening are in Repair, Revision and/or Reconstruction coding sections.
Hopefully this information helps.
