CPT® Code 57550

The CPT® Code 57550 refers to the excision of the cervical stump through a vaginal approach. This procedure is specifically indicated for patients who have previously undergone a sub-total hysterectomy and later develop cervical malignancy. During the excision, a tenaculum is utilized to grasp the cervix, allowing the physician to make an incision in the upper part of the vaginal mucosa that encircles the cervical stump. The procedure involves applying tension to the tenaculum, followed by both sharp and blunt dissection techniques to separate the bladder from the cervix and to break down any adhesions present. The excised cervical stump is removed along with surrounding parametrial tissue and a segment of the vagina, which is then sent for frozen section analysis to assess for malignancy. This procedure is critical in managing cervical cancer in patients with a history of hysterectomy, ensuring that any malignant tissue is effectively removed while preserving surrounding structures as much as possible.
