Maternal care for unsp congen malform of uterus, unsp tri

This code signifies antenatal care provided to a pregnant patient when there is a documented, but unspecified, congenital anomaly of the uterus. This includes conditions like uterine didelphys, bicornuate uterus, or septate uterus, where the specific type of malformation is not detailed in the medical record. The code also indicates that the trimester of pregnancy is not specified.

Use this code when the medical record clearly states maternal care is being provided due to a congenital uterine malformation, but the precise type of malformation is not documented. It is appropriate for encounters where the trimester of pregnancy is also not specified. Documentation should indicate the presence of a uterine anomaly impacting the pregnancy.

• Do not use this code if the specific type of uterine malformation (e.g., bicornuate uterus) is documented; instead, use a more specific O34.0- subcategory.
• Avoid this code if the trimester is known; select the appropriate O34.01, O34.02, or O34.03 code.
• Always sequence this code as a secondary diagnosis following the code for the obstetric encounter (e.g., Z34.00, Z34.80).
