CPT® Code 56620

A partial simple vulvectomy, as described by CPT® Code 56620, involves the surgical removal of a portion of the vulva, which is the external part of the female genitalia. The vulva encompasses several anatomical structures, including the mons pubis, labia majora and minora, clitoris, vaginal vestibule, glands, urethral opening, and vaginal opening. This procedure is typically indicated for the treatment of severe leukoplakia or confirmed malignancies of the vulva, such as extensive carcinoma in situ, microinvasive carcinoma, or Paget's disease. Unlike a radical vulvectomy, which involves a more extensive excision that extends into the perineal fascia, a simple vulvectomy focuses on removing only the affected portion of the vulva while preserving surrounding healthy tissue. The specific approach and extent of the excision are determined by the location and severity of the disease. During the procedure, careful marking of excision margins is performed to ensure adequate removal of diseased tissue while maintaining a margin of healthy tissue, which is crucial for optimal healing and reducing the risk of recurrence.
