ICD-10 Code B67.0 – Echinococcus granulosus infection of liver (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B67.0 – Echinococcus granulosus infection of liver
What it is
B67.0 identifies hydatid disease caused by Echinococcus granulosus in the liver. Use it when documentation states hepatic echinococcosis, liver hydatid cyst, or similar wording.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include right upper quadrant pain, hepatomegaly, or an incidental liver cyst on imaging, with diagnosis supported by serology or characteristic imaging.
When to use this code
Use this code when the provider documents Echinococcus granulosus infection limited to the liver. It may also apply when a hepatic hydatid cyst is clearly linked to this parasite. If the record does not specify the organism or organ site, check documentation.
Do not use for
Do not use B67.0 for echinococcosis involving other organs or for nonspecific liver cysts without documented parasitic cause. Check documentation if the chart only says “hydatid disease” without liver involvement.
Coding tip
Confirm both the organism and the liver site in the provider note before assigning B67.0.
