CPT® Code 0164T

Add-On Code

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

The CPT® Code 0164T refers to the procedure of removing a total disc arthroplasty, specifically an artificial disc, through an anterior approach at each additional interspace in the lumbar region. This procedure is performed when a previously implanted artificial disc needs to be extracted from the lumbar spine, and it is important to note that this code is applicable only for each additional interspace beyond the first one that is removed. The process begins with making an incision in the abdomen, allowing access to the lumbar spine. During the procedure, the surrounding muscles and tissues are carefully retracted to expose the spinal column. The surgeon then locates the artificial disc implant, which may be adhered to surrounding tissues due to fibrous tissue or adhesions. To facilitate the removal, distraction is applied to open the intervertebral space, allowing the implant to be unseated from its position between the adjacent vertebrae. Once the artificial disc is successfully removed, the surgical site is explored and any necessary debridement is performed to ensure a clean area for healing. Finally, the muscle and tissue are closed in their original position to complete the wound repair, ensuring proper recovery and minimizing complications.
