Maternal care for abnormality of vagina, third trimester

This code signifies medical supervision and management provided to a pregnant patient during her third trimester due to an identified anomaly or structural defect of the vagina. This includes congenital malformations, acquired strictures, or other significant anatomical variations that may impact the pregnancy or delivery.

Assign this code when documentation specifies maternal care for a vaginal abnormality diagnosed or managed during the third trimester of pregnancy. Supporting documentation would include physician notes detailing the specific vaginal anomaly and the trimester of care, often alongside imaging reports or surgical history.

• Always confirm the trimester of care documented; this code is specific to the third trimester.
• Do not use this code for routine screening or incidental findings without documented clinical significance requiring maternal care.
• Sequence this code as a secondary diagnosis following the primary obstetric code (e.g., Z3A.xx for weeks of gestation).
