CPT® Code 51720

The procedure described by CPT® Code 51720 involves the bladder instillation of an anticarcinogenic agent, which is a substance used to prevent or treat cancer within the bladder. This procedure is performed following the manufacturer's specific instructions for the preparation of the anticarcinogenic agent. Initially, the urethral orifice, which is the external opening of the urethra, is thoroughly cleansed to minimize the risk of infection. A catheter, a thin flexible tube, is then carefully inserted through the urethra and advanced into the bladder. Prior to instillation, the bladder is drained of any urine to ensure that the anticarcinogenic agent can be effectively administered without dilution. Once the bladder is prepared, the anticarcinogenic agent is instilled through the catheter. After the instillation, the catheter is removed, and the patient is repositioned to facilitate the distribution of the agent across all surfaces of the bladder. This repositioning involves the patient rotating periodically from the right side to the back, then to the left side, and finally to the stomach, ensuring comprehensive contact with the bladder lining. The retention time for the agent in the bladder may last up to 2 hours, allowing for optimal therapeutic effect. Upon completion of the treatment period, the patient is instructed to empty the bladder into the toilet, effectively concluding the procedure.
