    ICD-10-CM Code For Other Inflammatory Liver Diseases: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K75 includes inflammatory liver disorders such as autoimmune and nonspecific hepatitis, granulomatous hepatitis, and other specified inflammatory hepatic conditions that are not classified elsewhere. These ICD-10-CM diagnosis codes are used to document clinical presentations of hepatic inflammation, capture disease severity, organ involvement, and clinical complexity relevant to management and prognosis. Accurate coding within the ICD-10-CM K75 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM K75: Other Inflammatory Liver Diseases Overview

    This code group represents a set of inflammatory conditions primarily affecting the liver, including various forms of hepatitis and other noninfectious inflammatory hepatic disorders. These diagnoses target hepatic inflammation, immune-mediated injury, and related liver pathology that can affect hepatic function. Accurate coding matters for appropriate claim processing, clinical recordkeeping, and ensuring the medical necessity and severity of liver disease are documented for reimbursement.

Select the most specific code available based on clinical findings, histology, or stated diagnosis in the medical record.

    Typical Clinical Scenarios

    • An adult patient presents to the emergency department with sudden onset right upper quadrant pain, fever, jaundice, and markedly elevated liver enzymes and bilirubin after several days of systemic illness; imaging shows hepatic abscesses or focal inflammatory lesions consistent with acute hepatic inflammation. A diagnosis from this group is assigned when acute inflammatory liver disease is identified as the primary process causing the acute presentation. Typical codes: K75.0, K75.2
    • A middle-aged patient with known autoimmune disease is followed in hepatology clinic for chronic inflammatory liver involvement characterized by persistent elevated transaminases and histologic evidence of chronic active hepatitis on liver biopsy; symptoms fluctuate over months with fatigue and mild hepatomegaly. A chronic inflammatory liver diagnosis from this group is used to capture ongoing autoimmune or chronic inflammatory processes driving progressive liver injury. Typical codes: K75.4, K75.1
    • A hospitalized patient with sepsis and multi-organ dysfunction develops new cholestasis and biochemical signs of liver injury thought to be secondary to systemic infection or drug-induced hepatic inflammation; the liver inflammation is coded as a comorbidity complicating the hospital course and influencing management. Typical codes: K75.81, K75.89, K75.9
