CPT® Code 55862

Exposure of prostate, any approach, for insertion of radioactive substance; with lymph node biopsy(s) (limited pelvic lymphadenectomy)

The procedure described by CPT® Code 55862 involves the surgical exposure of the prostate gland through various approaches, primarily for the purpose of inserting a radioactive substance as part of brachytherapy treatment. Brachytherapy is a form of radiation therapy where radioactive seeds are implanted directly into or near a tumor, allowing for targeted treatment while minimizing exposure to surrounding healthy tissue. The surgical approach can be either retropubic, which involves an incision in the lower abdomen, or perineal, which involves an incision in the perineal area. In the retropubic approach, the bladder is carefully displaced to access the area behind the pubic bone, allowing the surgeon to reach the prostate. A finger guide may be utilized in the rectum to assist in the precise placement of a hollow applicator needle into the prostate tissue. Once the needle is accurately positioned, radioactive seeds are introduced through the needle and implanted into the prostate. This process is repeated multiple times, with the needle being withdrawn and repositioned in small increments to ensure comprehensive coverage of the target area. Additionally, this procedure includes a limited pelvic lymphadenectomy, which involves the biopsy of lymph nodes, typically focusing on the unilateral obturator lymph node chain(s). This is distinct from an extended lymphadenectomy, which would involve the removal of all lymph nodes on both sides, including those along the obturator fossa, external iliac vein, and hypogastric artery.
