CPT® Code 22101

Partial excision of posterior vertebral component (eg, spinous process, lamina or facet) for intrinsic bony lesion, single vertebral segment; thoracic

The CPT® Code 22101 refers to the procedure of partial excision of a posterior vertebral component, specifically for an intrinsic bony lesion located in a single vertebral segment of the thoracic spine. This procedure involves the surgical removal of a portion of the vertebra, which may include structures such as the spinous process, lamina, or facet. The physician initiates the process by making an incision over the affected vertebral segment, which allows access to the underlying tissues. The incision is carefully extended through the paravertebral muscles to reach the bony lesion, which could be a bone spur or another type of bony growth. Once the lesion is exposed, the physician excises the affected portion of the vertebral component, thereby alleviating any associated symptoms or complications. After the excision, the incision is closed, completing the procedure. It is important to note that this code is specifically designated for thoracic segments, with separate codes available for cervical and lumbar segments, as well as for additional segments if multiple excisions are performed.
