Intrahepatic cholestasis of pregnancy, third trimester

This code signifies a liver condition unique to pregnancy, characterized by impaired bile flow within the liver, leading to an accumulation of bile acids in the bloodstream. It typically manifests with severe itching (pruritus) and can pose risks to both the mother and fetus. This specific code indicates the condition is occurring during the third trimester of pregnancy.

Utilize this code when a pregnant patient in her third trimester is diagnosed with intrahepatic cholestasis, often presenting with generalized pruritus without a rash, elevated serum bile acids, and abnormal liver function tests. Documentation should clearly state the diagnosis, the trimester, and any associated symptoms or lab findings.

• Ensure documentation explicitly states "third trimester" for accurate code assignment.
• Do not confuse with other liver disorders in pregnancy, such as pre-eclampsia with severe features (HELLP syndrome) or acute fatty liver of pregnancy.
• Code any associated symptoms, such as pruritus (L29.8), as secondary diagnoses if documented.
