CPT® Code 62143

The procedure described by CPT® Code 62143 involves the replacement of a bone flap or a prosthetic plate in the skull. This surgical intervention is typically performed to address defects or injuries to the cranial structure. The process begins with the exposure of the site where the skull injury or defect is located. If the original cranial bone, which may have been previously removed due to trauma or surgical necessity, is available, it is retrieved from a subcutaneous pocket. This retrieval is considered a separately reportable procedure. Once the bone graft is prepared, it is carefully returned to the defect site and secured in place using various methods such as sutures, wires, or a combination of miniplate and screws to ensure stability and proper alignment. In cases where the original bone flap is not available or suitable for reattachment, a prosthetic plate can be utilized as an alternative. The surgeon selects an appropriately sized prosthetic plate, which is then secured to the skull using similar fixation techniques. After the bone or plate is in place, the overlying soft tissue and skin are meticulously repaired in layers to promote optimal healing and restore the integrity of the cranial structure.
