ICD-10 Code B67.7 – Echinococcus multilocularis infection, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B67.7 – Echinococcus multilocularis infection, unspecified
What it is
B67.7 identifies an infection caused by Echinococcus multilocularis when the record does not specify the organ involved or other detail. Use it for documented alveolar echinococcosis without a more specific code.
Clinical signs
Clinical features vary; refer to documentation. Patients may have findings consistent with parasitic liver disease or other organ involvement, but the chart should support Echinococcus multilocularis infection specifically.
When to use this code
Use B67.7 when the clinician documents Echinococcus multilocularis infection and does not name a site or further subtype. It also fits cases where the note confirms the organism but leaves the anatomic detail unspecified. If the record identifies a more specific manifestation, code that instead.
Do not use for
Do not use this code for Echinococcus granulosus infection or for hydatid disease that is documented under a different organism. Check documentation if the note only says “echinococcosis” without confirming E. multilocularis.
Coding tip
Code the organism and site separately when documentation provides both, and default to B67.7 only when the infection is confirmed but unspecified.
