CPT® Code 57106

The procedure described by CPT® Code 57106 refers to a partial vaginectomy, which involves the surgical removal of a portion of the vaginal wall. This procedure is specifically characterized by the excision of the vaginal epithelium while preserving the surrounding paravaginal tissue, known as the paracolpium. During the operation, the surgeon removes the vaginal wall along with a 2 cm margin of healthy tissue that is located distal to the lesion, ensuring that the area surrounding the lesion is adequately addressed. The surgical approach begins with an incision made across the top of the vaginal vault, followed by two longitudinal full-thickness incisions—one on the anterior (ventral) side and another on the posterior (dorsal) side of the vaginal wall. These incisions extend from the top of the vaginal vault down to a point 2 cm distal to the identified lesion. The upper section of the vaginal wall, which contains the lesion, is then excised. It is important to note that if vaginal reconstruction is necessary, such as the use of skin grafts, this may be reported separately and can occur either during the same surgical session or at a later date. This procedure is distinct from other related codes, such as CPT® Code 57107, which involves a more extensive removal of the vaginal wall and surrounding tissues, and CPT® Code 57109, which includes additional lymphadenectomy procedures.
