CPT® Code 28546

The procedure described by CPT® Code 28546 refers to the percutaneous skeletal fixation of a dislocated tarsal bone, excluding the talotarsal joint. This surgical intervention is performed to restore the proper alignment of the tarsal bones, which are located in the midfoot and play a crucial role in foot stability and mobility. The process begins with a small incision made over the affected tarsal joint, allowing access to the dislocated bones. The surgeon then manipulates the dislocated bones back into their correct anatomical position, a process known as reduction. To confirm that the bones are properly aligned, radiographs (X-rays) are taken, which are reportable separately from the procedure itself. Following the reduction, additional small incisions are made at the sites where pins or Kirschner wires will be inserted. A specialized drill is utilized to create a corticotomy, which is a small opening in the bone, facilitating the insertion of the fixation devices. The pins or wires are then carefully advanced through one of the involved tarsal bones, across the joint, and into the adjacent tarsal bone, effectively stabilizing the joint and maintaining the alignment achieved during the reduction. After the placement of all fixation devices, another set of radiographs is performed to ensure that the anatomical reduction has been successfully maintained. This procedure is critical for preventing complications associated with dislocated tarsal bones, such as chronic pain, instability, and impaired function of the foot.
