CPT® Code 22112

Partial excision of vertebral body, for intrinsic bony lesion, without decompression of spinal cord or nerve root(s), single vertebral segment; thoracic

The CPT® Code 22112 refers to the procedure of partial excision of a vertebral body specifically for the treatment of an intrinsic bony lesion located within a single thoracic vertebral segment. This procedure is performed without the need for decompression of the spinal cord or nerve roots, indicating that the primary focus is on the removal of the bony lesion itself rather than addressing any potential compression issues affecting the spinal structures. During the procedure, a surgical incision is made over the affected vertebral segment or just lateral to the vertebra in question. The paravertebral muscles are then carefully exposed, either by incision or retraction, to allow access to the vertebral body. Once the vertebral body is exposed, the surgeon locates the lesion and evaluates its extent through visual inspection and, if necessary, radiographic imaging. The surgeon meticulously maps out the area of bone that needs to be removed to ensure complete excision of the lesion while safeguarding surrounding nerve roots and other critical structures. The actual removal of the bony lesion is accomplished using specialized instruments such as a high-speed bur and/or curette. After the lesion has been completely excised, the surgical incision is closed in layers to promote proper healing. This procedure is distinct from other related codes, such as 22110 for cervical vertebral body lesions, 22214 for lumbar vertebral body lesions, and 22116 for excisions involving additional vertebral bodies beyond the first.
