CPT® Code 0222T

Add-On Code

Placement of a posterior intrafacet implant(s), unilateral or bilateral, including imaging and placement of bone graft(s) or synthetic device(s), single level; each additional vertebral segment (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 0222T involves the placement of a posterior intrafacet implant, which can be performed unilaterally or bilaterally. This procedure is specifically aimed at addressing issues related to the facet joints, which are the paired posterior vertebral joints located between the vertebrae of each segment of the spine. These joints play a crucial role in providing stability and facilitating movement 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 begins with an incision over the affected vertebral segment, allowing for direct access to the facet joints. Imaging guidance is utilized to enhance visualization during the procedure, ensuring precision in the placement of the implant. The intervertebral ligament is divided to expose the lamina, which may require partial or complete excision to reveal the involved nerve root. Following exploration of the facet joints, stabilization is achieved through the insertion of a posterior intrafacet implant, which may include devices such as a facet screw system or a locking screw and nut device. In cases where a bone graft is necessary, it can be harvested from the local area or from the iliac crest, prepared, and placed between the facets. Additionally, bone cement may be injected to further secure the implant. This procedure can be performed on one side or both sides of the paired facet joints, depending on the clinical need. Upon completion, meticulous attention is given to controlling any bleeding, irrigating the wound, and closing the incisions to promote optimal healing.
