CPT® Code 0202T

Posterior vertebral joint(s) arthroplasty (eg, facet joint[s] replacement), including facetectomy, laminectomy, foraminotomy, and vertebral column fixation, injection of bone cement, when performed, including fluoroscopy, single level, lumbar spine

The procedure described by CPT® Code 0202T involves arthroplasty of the posterior vertebral joint(s), specifically targeting the facet joints located in the lumbar spine. The facet joints, which are paired posterior joints situated between the vertebrae, play a crucial role in providing stability and facilitating movement in the spine. These joints have flat articular surfaces that allow for smooth articulation between adjacent vertebrae. When the intervertebral disc sustains damage, the facet joints can become compromised, leading to conditions such as nerve compression and significant back pain. The surgical intervention aims to repair or replace the damaged facet joints to alleviate pain and restore function. During the procedure, the surgeon makes an incision over the affected lumbar segment to access the facet joints. Fluoroscopy, a real-time imaging technique, is utilized to enhance visualization of the surgical site, ensuring precision in the execution of the procedure. The intervertebral ligament is carefully divided to expose the lamina, which may be partially or fully excised to reveal the involved nerve root. The surgeon then explores the facet joints, excising the damaged joint, typically focusing on the lower facet, although the upper facet may also be removed if necessary. To relieve nerve compression, the vertebral foramen is enlarged using specialized instruments. Stabilization of the spine is achieved through the placement of a facet joint prosthesis or a vertebral column fixator device, and bone cement may be injected to enhance stability. The procedure concludes with meticulous control of bleeding, irrigation of the wound, and closure of the incisions. This code specifically reports surgical intervention at a single level of the lumbar spine, addressing the complexities associated with facet joint repair and stabilization.
