ICD-10 Code B67.4 – Echinococcus granulosus infection, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B67.4 – Echinococcus granulosus infection, unspecified
What it is
This code identifies infection with Echinococcus granulosus when the site or specific manifestation is not documented. You use it for echinococcosis caused by the dog tapeworm, without further detail.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings may include a cystic mass, abdominal discomfort, or incidental imaging findings consistent with hydatid disease.
When to use this code
Use B67.4 when the record confirms Echinococcus granulosus infection but does not specify the organ involved or a more precise form of disease. It is also appropriate when documentation only states “hydatid disease” or “echinococcosis” without additional detail. Check the note for any specified site before assigning this code.
Do not use for
Do not use this code if the documentation identifies a specific organ or type of echinococcosis with a more exact ICD-10-CM code. Do not use it for suspected infection without confirmation; check documentation.
Coding tip
Query the provider for the involved site when the chart says only “hydatid cyst” or “echinococcosis.”
