CPT® Code 63044

Add-On Code

Laminotomy (hemilaminectomy), with decompression of nerve root(s), including partial facetectomy, foraminotomy and/or excision of herniated intervertebral disc, reexploration, single interspace; each additional lumbar interspace (List separately in addition to code for primary procedure)

The CPT® Code 63044 refers to a surgical procedure known as laminotomy or hemilaminectomy, which involves the re-exploration of a lumbar vertebra that has previously undergone decompression. This procedure is specifically aimed at relieving pressure on the nerve root(s) by removing portions of the facet joint and the bony arch that lies between the vertebral body and the spinal cord. The term 'laminotomy' indicates that a portion of the lamina, which is the bony structure that forms the back of the vertebral arch, is removed to access the spinal canal and the nerve roots. In addition to the decompression, this procedure may also include a partial facetectomy, which is the removal of part of the facet joint, and a foraminotomy, which is the widening of the foramen (the opening through which nerve roots exit the spinal column). Furthermore, if there is a herniated intervertebral disc present, the surgeon may excise this disc material to alleviate nerve compression. It is important to note that this code is used for each additional lumbar interspace treated during the procedure, and it is listed separately in addition to the code for the primary procedure. For procedures involving the cervical spine, different codes are utilized, specifically CPT® Code 63040 for the neck and CPT® Code 63042 for the lower back. If additional vertebrae are involved, CPT® Code 63043 is applicable for the neck, while CPT® Code 63044 is used for additional lumbar interspaces.
