Genital varices in pregnancy, third trimester

This code signifies the presence of varicose veins affecting the external genitalia (vulva, perineum) during the third trimester of pregnancy. These varices are a common physiological change in pregnancy due to increased blood volume and pressure on pelvic veins.

Apply this code when documentation explicitly states the diagnosis of genital varices and specifies that the patient is in her third trimester of pregnancy. This diagnosis is typically made through physical examination.

• Ensure the documentation clearly specifies "genital" or "vulvar" varices, not just general lower extremity varices.
• Verify the trimester is explicitly stated as the third; avoid assuming based on gestational age alone if not documented.
• Do not use this code for varices in other locations (e.g., O22.0- for lower extremity varices).
