CPT code 58573 denotes a laparoscopic hysterectomy performed for an enlarged uterus—typically due to fibroids—where the uterus, cervix, and fallopian tubes or ovaries are removed through trocar ports or via the vaginal canal, and the uterus usually weighs more than 250 g. This code captures a common gynecologic procedure that has implications for surgical planning, site-of-service decisions, and national utilization monitoring because enlarged uteri often require different operative techniques and resource use than standard hysterectomy.
