ICD-10 Code B67.5 – Echinococcus multilocularis infection of liver (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B67.5 – Echinococcus multilocularis infection of liver
What it is
This code identifies alveolar echinococcosis involving the liver, caused by Echinococcus multilocularis. It is a parasitic infection that typically forms an infiltrative hepatic lesion and may spread locally or to other organs.
Clinical signs
Clinical features vary; refer to documentation. Common findings include a liver mass, abdominal pain, hepatomegaly, or abnormal imaging suggestive of infiltrative parasitic disease.
When to use this code
Use B67.5 when the provider documents Echinococcus multilocularis infection specifically affecting the liver. It may also apply when imaging, pathology, or specialist notes confirm hepatic alveolar echinococcosis. Do not code from suspicion alone; check documentation for confirmed site and organism.
Do not use for
Do not use this code for other echinococcal infections, such as cystic hydatid disease, or for liver lesions without confirmed parasitic cause. Check documentation if the organism or hepatic involvement is not clearly stated.
Coding tip
Capture the exact organism and anatomic site from the record before assigning B67.5.
