CPT® Code 22116

Add-On Code

Partial excision of vertebral body, for intrinsic bony lesion, without decompression of spinal cord or nerve root(s), single vertebral segment; each additional vertebral segment (List separately in addition to code for primary procedure)

The CPT® Code 22116 refers to the procedure of partial excision of a vertebral body specifically for the treatment of an intrinsic bony lesion. This procedure is performed without the need for decompression of the spinal cord or nerve roots and is applicable to a single vertebral segment. The term "partial excision" indicates that only a portion of the vertebral body is removed, which is typically necessary when a bony lesion is present. The procedure begins with an incision made over the affected vertebral segment or just lateral to the vertebra in question. The surrounding paravertebral muscles are then 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, often using visual inspection and radiographic imaging to guide the procedure. The surgeon carefully maps out the amount of bone that needs to be removed to ensure complete excision of the lesion while protecting adjacent nerve roots and other vital structures. The removal of the bony lesion is typically accomplished using specialized instruments such as a high-speed bur and/or a curette. After the lesion has been completely excised, the incision is meticulously closed in layers to promote proper healing. It is important to note that this code is used for each additional vertebral segment involved in the procedure, and it should be listed separately in addition to the code for the primary procedure. For reference, related codes include 22110 for excision of a bone lesion of one cervical vertebral body, 22112 for a lesion of one thoracic vertebral body, and 22214 for a lesion of one lumbar vertebral body.
