ICD-10 Code B67.6 – Echinococcus multilocularis infection, other and multiple sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B67.6 – Echinococcus multilocularis infection, other and multiple sites
What it is
B67.6 identifies alveolar echinococcosis caused by Echinococcus multilocularis when infection involves other or multiple sites. Use it for documented multi-organ or non-specific site involvement, not for unspecified echinococcosis.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include slowly progressive mass effect, abdominal pain, or signs related to affected organs, with imaging or pathology supporting parasitic disease.
When to use this code
Use this code when the record clearly states Echinococcus multilocularis infection and describes more than one site or a site not captured by a more specific code. It is appropriate when the provider documents alveolar echinococcosis involving multiple organs, or “other sites” without a single primary location.
Check documentation for the exact anatomic sites and whether the infection is confirmed versus only suspected. If the chart names a single organ, code the more specific site instead.
Do not use for
Do not use B67.6 for hydatid disease caused by other Echinococcus species or for unspecified echinococcosis. Do not use it when the record identifies only one specific site that has its own code.
Coding tip
Look for the organism name and all documented sites; specificity in the note determines whether B67.6 is the best match.
