CPT® Code 55815

Prostatectomy, perineal radical; with bilateral pelvic lymphadenectomy, including external iliac, hypogastric and obturator nodes

The procedure described by CPT® Code 55815 is a perineal radical prostatectomy combined with a bilateral pelvic lymphadenectomy. This surgical intervention involves the removal of the prostate gland and seminal vesicles through an incision made in the perineum, which is the area between the scrotum and the anus. The procedure is indicated primarily for patients diagnosed with prostate cancer, particularly when there is a need to assess and potentially remove lymph nodes that may harbor malignant cells. The lymphadenectomy is performed first to evaluate the status of the pelvic lymph nodes, specifically targeting the external iliac, hypogastric, and obturator nodes. This step is crucial as it helps determine the extent of cancer spread and informs subsequent treatment decisions. The surgical technique emphasizes careful dissection to preserve important anatomical structures, such as the genitofemoral nerve and psoas muscle, which are vital for maintaining function post-surgery. The detailed steps of the procedure ensure that the prostate is completely excised while minimizing damage to surrounding tissues, thereby enhancing recovery and preserving urinary and sexual function when possible.
