ICD-10 Code K76.5 – Hepatic veno-occlusive disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K76.5 – Hepatic veno-occlusive disease
What it is
K76.5 identifies hepatic veno-occlusive disease, a condition where small veins in the liver become blocked. This can impair blood flow through the liver and cause liver injury.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include liver enlargement, abdominal pain or swelling, and jaundice, especially when the diagnosis is confirmed by imaging or pathology.
When to use this code
Use K76.5 when the provider documents hepatic veno-occlusive disease or sinusoidal obstruction syndrome affecting the liver. Apply it for confirmed cases, including those supported by clinical assessment, imaging, or biopsy. Do not code it from nonspecific liver dysfunction alone.
Do not use for
Do not use this code for general hepatitis, cirrhosis, or portal vein thrombosis unless hepatic veno-occlusive disease is specifically documented. Check documentation if the record only mentions liver congestion or obstruction.
Coding tip
Code only when the provider clearly names hepatic veno-occlusive disease; if the wording is unclear, query for specificity.
