CPT® Code 63057

Add-On Code

Transpedicular approach with decompression of spinal cord, equina and/or nerve root(s) (eg, herniated intervertebral disc), single segment; each additional segment, thoracic or lumbar (List separately in addition to code for primary procedure)

The CPT® Code 63057 refers to a surgical procedure involving a transpedicular approach for the decompression of the spinal cord, cauda equina, and/or nerve root(s), particularly in cases of a herniated intervertebral disc. This procedure is performed on a single segment of the thoracic or lumbar spine, with the option to list additional segments separately. The term "transpedicular" indicates that the approach involves the 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 begins with a skin incision made at the lateral margin of the spinous process of the affected disc, followed by the elevation of paraspinal muscles to access the underlying structures. The lamina and facet joint are then exposed, allowing for the removal of specific bony portions to relieve pressure on the spinal cord and nerve roots. This detailed approach is crucial for addressing conditions such as herniated discs, where decompression is necessary to alleviate pain and restore function. The procedure is complex and requires careful manipulation of the spinal anatomy to ensure successful outcomes while minimizing risks to surrounding structures.
