Genital varices in pregnancy, second trimester

This code signifies the presence of varicose veins affecting the external genitalia (vulva, perineum) specifically occurring during the second trimester of pregnancy. These varices are typically caused by increased blood volume and pressure on pelvic veins during gestation. Patients may experience discomfort, pain, or swelling in the affected area.

Apply this code when documentation clearly indicates the diagnosis of genital varices in a pregnant patient who is currently in her second trimester. Supporting documentation should include a physician's diagnosis of vulvar or perineal varicosities and a clear indication of the gestational period.

• Ensure the trimester is explicitly documented; do not assume based on estimated due date.
• Do not confuse with O22.0- (Varicose veins of lower extremity in pregnancy) or O22.2- (Superficial thrombophlebitis in pregnancy).
• Sequence this code as a secondary diagnosis if the primary reason for the encounter is related to another pregnancy complication or routine prenatal care.
