CPT® Code 54405

The CPT® Code 54405 refers to the procedure for the insertion of a multi-component, inflatable penile prosthesis. This device is designed to assist patients in achieving and maintaining penile rigidity, which is essential for sexual intercourse. The prosthesis consists of several key components: two inflatable intracorporal cylinders that are placed within the corpora cavernosa of the penis, a scrotal pump that allows the patient to inflate and deflate the device, and a fluid reservoir that is typically positioned in the abdomen. The procedure involves a series of surgical steps, including the placement of a Foley catheter in the bladder to facilitate drainage during the operation. A transverse incision is made at the penoscrotal junction to access the necessary anatomical structures. The dartos fascia is incised to expose the tunica albuginea of the corpora cavernosa, which are then prepared for the insertion of the inflatable cylinders. The procedure requires careful manipulation to avoid injury to surrounding tissues, particularly the urethra. After the cylinders are inserted and tested for functionality, the pump is placed in a subdartos pouch created in the scrotum, ensuring that the deflation button is positioned for easy access. The reservoir is then inserted into the retropubic space, and all components are connected and checked for proper operation before closing the incisions. This procedure is typically indicated for patients experiencing erectile dysfunction who have not responded to less invasive treatments.
