CPT® Code 51020

The procedure described by CPT® Code 51020 involves a surgical intervention on the urinary bladder, specifically a cystotomy or cystostomy. In this context, a cystotomy refers to the surgical incision into the bladder, while a cystostomy indicates the creation of an opening into the bladder. The primary goal of this procedure is to access the internal lumen of the bladder for therapeutic purposes. This can be achieved through two methods: either by fully exposing and incising the bladder or by making a smaller incision over the bladder and puncturing the bladder wall to gain access. Once access is obtained, the procedure focuses on the destruction of abnormal tissue within the bladder. This is accomplished through two main techniques: fulguration, which involves the use of an electrocautery device to destroy the tissue by applying heat, or by inserting radioactive material directly into the lesion. The electrocautery device is carefully advanced to the site of the abnormal tissue, activated, and used to effectively destroy the lesion. Alternatively, a laser may be employed for the same purpose. In cases where radioactive material is utilized, a delivery device is inserted into the bladder and positioned precisely at the lesion site, allowing for the embedding of a radioactive pellet into the mucosa or bladder wall to treat the abnormal tissue. This procedure is significant in managing various bladder conditions, particularly those involving abnormal tissue growths or lesions.
