CPT® Code 63056

Transpedicular approach with decompression of spinal cord, equina and/or nerve root(s) (eg, herniated intervertebral disc), single segment; lumbar (including transfacet, or lateral extraforaminal approach) (eg, far lateral herniated intervertebral disc)

The CPT® Code 63056 refers to a surgical procedure known as a transpedicular approach with decompression of the spinal cord, cauda equina, and/or nerve root(s). This procedure is typically indicated for conditions such as a herniated intervertebral disc affecting a single segment of the lumbar spine. The transpedicular approach involves the surgical removal of part of one of the two pedicles, which are bony structures that project from the vertebra and help form the vertebral arch that encases the spinal cord. The procedure is performed through a skin incision made at the lateral margin of the spinous process of the affected lumbar disc. The surgical technique includes elevating the paraspinal muscles, exposing the lamina and facet joint, and utilizing a high-speed drill to remove specific bony structures to access the spinal cord and nerve roots. The goal of this procedure is to relieve pressure caused by herniated disc material or bone spurs, thereby alleviating symptoms associated with nerve compression. This code is specifically designated for lumbar spine procedures, distinguishing it from similar codes that pertain to thoracic spine decompression.
