CPT® Code 55812

The procedure described by CPT® Code 55812 refers to a perineal radical prostatectomy, which is a surgical intervention aimed at the removal of the prostate gland and seminal vesicles through an incision made in the perineum, the area between the scrotum and the anus. This procedure is typically indicated for patients diagnosed with prostate cancer. In cases where lymph node involvement is suspected, a limited pelvic lymphadenectomy is performed concurrently. This involves exploring the pelvic lymph nodes on one side of the body without entering the peritoneal cavity, allowing for the assessment and potential biopsy of lymph nodes that may harbor malignant cells. The surgical technique emphasizes the preservation of critical structures, such as the genitofemoral nerve and psoas muscle, to minimize postoperative complications. The procedure is comprehensive, involving meticulous dissection and removal of the prostate while ensuring that surrounding tissues are handled with care to maintain function and reduce the risk of adverse effects. The detailed steps of the procedure highlight the complexity and precision required in performing a radical prostatectomy with lymph node biopsy, making it essential for medical coders and billers to understand the nuances of this surgical intervention for accurate coding and billing purposes.
