Genital tract-skin fistula, female

This code describes an abnormal communication or tract between the female genital tract (e.g., vagina, uterus) and the skin. This fistula allows for the passage of bodily fluids, such as urine or menstrual blood, from the genital tract to the external skin surface. It often results from trauma, infection, surgery, or radiation.

Use this code for documented cases of a female genital tract-skin fistula, such as a rectovaginal fistula extending to the perineal skin, or a vesicovaginal fistula that has eroded through the skin. Documentation should clearly specify the involvement of both the genital tract and the skin, and the female gender of the patient.

• Ensure documentation specifies the female genital tract as the origin of the fistula, not just a general skin fistula.
• Distinguish from internal fistulas (e.g., vesicovaginal fistula without skin involvement) which would be coded elsewhere.
• Consider an additional code to identify the underlying cause or associated complications, if known and documented.
