ICD-10 Code B67.3 – Echinococcus granulosus infection, other and multiple sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B67.3 – Echinococcus granulosus infection, other and multiple sites
What it is
B67.3 identifies hydatid disease caused by Echinococcus granulosus when the infection involves sites other than the liver or lungs, or when multiple sites are affected. Use it for documented echinococcal cyst disease at those locations.
Clinical signs
Clinical features vary; refer to documentation. Findings may reflect a cyst or mass effect in the involved organ, and imaging or pathology may confirm echinococcal infection.
When to use this code
Use B67.3 when the provider documents Echinococcus granulosus infection in an organ or tissue other than the liver or lungs, such as bone, spleen, kidney, or other specified sites. It also fits cases described as multiple-site involvement when the record does not support a more specific site code.
Do not use for
Do not use this code for hepatic or pulmonary hydatid disease, which have their own ICD-10-CM codes. Do not assign it when the record only says “cyst” or “mass” without documentation of Echinococcus granulosus.
Coding tip
Check the operative note, imaging report, or pathology report for the exact anatomic site before selecting B67.3.
