Liver and biliary tract disord in pregnancy, third trimester

This code signifies the presence of any liver or biliary tract pathology that arises or is exacerbated during the third trimester of pregnancy. This includes conditions such as intrahepatic cholestasis of pregnancy, gallstones, cholecystitis, or hepatitis, specifically when occurring in the final three months of gestation.

Apply this code when a pregnant patient in her third trimester is diagnosed with a disorder affecting the liver or biliary system. Documentation should clearly state the specific liver or biliary condition and confirm the gestational age falls within the third trimester (typically weeks 28 through delivery).

• Always code the specific liver or biliary condition first, followed by this code as a secondary diagnosis to indicate the pregnancy complication.
• Ensure the medical record explicitly states "third trimester" or provides gestational weeks that clearly fall within this period.
• Do not use this code if the liver or biliary disorder is unrelated to the pregnancy or if it occurred in an earlier trimester.
