CPT® Code 0098T

Add-On Code

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

The CPT® Code 0098T refers to a specific surgical procedure involving the revision and replacement of a total disc arthroplasty, specifically in the cervical region, using an anterior approach. This procedure is performed when there is a need to revise an existing artificial disc due to various factors such as persistent pain, degenerative changes, or misalignment of the spine at the treated or adjacent disc spaces. The surgery involves making an incision at the front of the neck, just off the midline of the spine, allowing access to the cervical spine. During the procedure, the esophagus is carefully retracted to provide a clear view of the surgical site, while nerves and arteries are identified and protected to prevent any injury. The existing artificial disc is then exposed, and the surgeon evaluates the condition of the surrounding vertebral bodies and the amount of bone loss or damage present. If deemed appropriate, the existing artificial disc is removed, and the intervertebral space is prepared for the insertion of a new artificial disc. This preparation includes milling and shaping the end plates to ensure a proper fit for the new device. The new artificial disc is then inserted, ensuring that the normal curvature of the cervical spine is maintained. The procedure is reported using CPT® Code 0098T for each additional interspace that undergoes revision, following the primary procedure, which is separately reportable.
