ICD-10 Code K74.00 – Hepatic fibrosis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K74.00 – Hepatic fibrosis, unspecified
What it is
K74.00 identifies fibrosis of the liver when the record does not specify the cause, stage, or whether cirrhosis is present. It means there is scarring in hepatic tissue, but the documentation is not detailed enough for a more specific code.
Clinical signs
Clinical features vary; refer to documentation. Fibrosis may be noted on imaging, biopsy, or specialist assessment, and the chart may describe chronic liver scarring without confirming cirrhosis.
When to use this code
Use K74.00 when the provider documents hepatic fibrosis and does not identify a more specific fibrosis type or underlying liver disease. It also fits when the note confirms liver scarring but leaves the stage or cause unspecified. If cirrhosis, alcoholic liver disease, or another defined disorder is documented, code that condition instead.
Do not use for
Do not use this code for cirrhosis, biliary fibrosis, or fibrosis tied to a documented specific liver disease when a more precise code is available. Check documentation.
Coding tip
Query for the cause and stage of fibrosis when the record only says “liver fibrosis,” because specificity may change the code selection.
