CPT® Code 22100

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

The procedure described by CPT® Code 22100 involves the partial excision of a posterior vertebral component, which may include structures such as the spinous process, lamina, or facet, specifically targeting an intrinsic bony lesion within a single vertebral segment located in the cervical region. This surgical intervention is typically indicated when there is a need to remove a bony growth or abnormality, such as a bone spur, that may be causing discomfort or other complications. The physician initiates the procedure by making an incision over the affected vertebral segment, which allows access to the underlying structures. The incision is carefully extended through the paravertebral muscles to reach the lesion. Once the lesion is accessed, the physician excises the affected portion of the vertebral component, thereby alleviating any associated symptoms. After the excision is completed, the incision is subsequently closed. It is important to note that this code is specifically designated for procedures performed on the cervical segment, while different codes are available for thoracic and lumbar segments, as well as for additional segments if multiple excisions are performed.
