O26.62Liver and biliary tract disorders in childbirth

O26.62 is the ICD-10-CM diagnosis code for liver and biliary tract disorders in childbirth. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 998 (Principal Diagnosis Invalid as Discharge Diagnosis), in MDC 14 (Pregnancy, Childbirth and the Puerperium), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

The Medicare Code Editor treats this as a maternity diagnosis, expected only for patients age 9 through 64.

It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 646.71 (liver and biliary tract disorders in pregnancy, delivered, with or without mention of antepartum condition).
