Revision including replacement of total disc arthroplasty (artificial disc), anterior approach, each additional interspace, lumbar (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 0165T pertains to the revision and replacement of a total disc arthroplasty, specifically focusing on the lumbar region of the spine. This procedure is performed using an anterior approach, which involves accessing the spine through an incision made in the abdomen. The term "revision" indicates that this procedure is conducted to address issues related to a previously implanted artificial disc, particularly when additional interspaces beyond the first require intervention. During the operation, the surgeon carefully navigates through the abdominal cavity to reach the spinal column, where the intervertebral muscles are retracted to expose the artificial disc. The surgical team meticulously identifies the implant, and any adhesions or fibrous tissue that may have formed around it are carefully freed to allow for a thorough exploration of the area. To facilitate the replacement or adjustment of the artificial disc, distraction is applied to open the intervertebral space. This step is crucial as it allows the surgeon to assess the positioning of the implant, which may have become unseated from its original placement between the vertebrae. If necessary, the implant components can be reseated, or if they are found to be malfunctioning, they may be replaced entirely. The procedure involves the removal of the failed implant or its components, followed by the preparation of the interspace for the insertion of a new prosthesis or component. Once the new implant is positioned correctly, the surgeon repairs the fascia and muscle tissue before closing the wound, often leaving a drain in place to prevent fluid accumulation. This comprehensive approach ensures that the revision of the total disc arthroplasty is performed effectively, addressing any complications that may have arisen from the initial surgery.
