    ICD-10-CM Code For Liver Disorders In Diseases Classified Elsewhere: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K77 includes liver disorders that are manifestations of diseases classified elsewhere, such as hepatic involvement from systemic infections, metabolic disorders, or toxic exposures. These ICD-10-CM diagnosis codes are used to document hepatic complications, organ-specific involvement, and clinical severity when the primary disease is indexed outside the liver chapter. Accurate coding within the ICD-10-CM K77 group supports appropriate claim adjudication and complete clinical documentation for care coordination and reimbursement.

    ICD-10-CM K77: Liver Disorders In Diseases Classified Elsewhere Overview

    The ICD-10-CM K77 code group represents liver disorders that occur as manifestations of diseases classified primarily in other chapters. These diagnoses target hepatic involvement such as hepatic necrosis, hepatic failure, or other liver pathology tied to systemic or infectious conditions. Accurate coding is important for complete clinical documentation and can affect reimbursement by reflecting the true clinical complexity.

    When to Use

    Use a code from this group when a patient has documented liver disease that is directly attributable to another underlying condition classified elsewhere and the hepatic condition is clinically significant. Assign these codes alongside the primary condition code to reflect hepatic involvement, severity, and to support accurate clinical documentation and billing.

    Typical Clinical Scenarios

    • An adult patient with known congestive heart failure presents with progressive jaundice, hepatomegaly, and right upper quadrant discomfort after weeks of worsening edema and exertional dyspnea; laboratory tests show mildly elevated bilirubin and cholestatic-pattern liver enzymes consistent with congestive hepatopathy, and imaging excludes biliary obstruction. A diagnosis from this group is assigned to capture liver dysfunction occurring as a manifestation of disease classified elsewhere (cardiac disease causing hepatic congestion). Typical codes: K77
    • A middle-aged patient with long-standing nonalcoholic fatty liver disease under care for metabolic syndrome develops increasing transaminases and hepatic fibrosis noted on elastography during routine follow-up; there is no primary liver disease listed in the patient’s problem list, and the hepatic abnormality is documented as secondary to systemic metabolic conditions. A code from this group is used to record the liver disorder that is attributed to another underlying systemic disease process. Typical codes: K77
    • A hospitalized patient admitted for sepsis from a urinary tract infection develops acute liver test abnormalities and coagulopathy during the admission, with clinicians documenting acute hepatic dysfunction secondary to the systemic infection. The liver disorder is coded from this group to denote hepatic involvement as a complication of the primary infectious process. Typical codes: K77
