Liver and biliary tract disord in pregnancy, first trimester

This code signifies the presence of a pre-existing or newly diagnosed liver or biliary tract disorder in a pregnant patient during her first trimester. This includes conditions such as cholestasis of pregnancy, gallstones, hepatitis, or other hepatic dysfunction directly impacting the pregnancy.

Apply this code when a pregnant patient in her first trimester presents with symptoms or a diagnosis related to liver or biliary tract pathology. Documentation should clearly state the specific liver/biliary condition and confirm the gestational age falls within the first trimester (up to the end of the 13th week).

• Always sequence this code after the primary obstetric code (e.g., O09.- for supervision of normal pregnancy).
• Ensure the medical record explicitly states "first trimester" or provides gestational age that falls within this period.
• Do not use this code for liver/biliary conditions unrelated to the pregnancy; use non-obstetric codes in such cases.
