Maternal care for abnlt of vulva and perineum, third tri

This code signifies medical supervision and management provided to a pregnant patient in her third trimester due to a diagnosed abnormality of the vulva or perineum. This could include conditions such as vulvar varicosities, perineal cysts, or other structural or pathological issues affecting these areas during the later stages of pregnancy. The care is specifically focused on monitoring and addressing these maternal conditions.

Apply this code when a pregnant patient in her third trimester receives antenatal care for a pre-existing or newly diagnosed abnormality of the vulva or perineum. Documentation should clearly state the specific vulvar or perineal abnormality and confirm that the patient is in her third trimester of pregnancy. This code is used for the maternal condition, not for fetal issues.

• Always sequence this code as a secondary diagnosis following a code from category Z3A (Gestational age) to indicate the specific trimester.
• Ensure the documentation specifies the type of vulvar or perineal abnormality; this code is for the maternal care related to the abnormality, not the abnormality itself.
• Do not confuse this with codes for complications of labor and delivery related to the vulva or perineum; this code is for antenatal care.
