About O26.64

O26.64 is the ICD-10-CM diagnosis code for intrahepatic cholestasis of pregnancy. It belongs to category O26 (maternal care for other conditions predominantly related to pregnancy), block O20-O29 (other maternal disorders predominantly related to pregnancy) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within O26.6 (liver and biliary tract disorders in pregnancy, childbirth and the puerperium), O26.64 is specifically for intrahepatic cholestasis of pregnancy. Related codes cover liver and biliary tract disorders in pregnancy (O26.61), liver and biliary tract disorders in childbirth (O26.62) and liver and biliary tract disorders in the puerperium (O26.63).

To report this condition, pick the subcode that matches the documentation: O26.641 (first trimester), O26.642 (second trimester), O26.643 (third trimester) and O26.649 (unspecified trimester).

Use an additional code for hepatic obstruction (K76.89).

It was added in FY2024, effective October 1, 2023.
