ICD-10 Code B67.61 – Echinococcus multilocularis infection, multiple sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B67.61 – Echinococcus multilocularis infection, multiple sites
What it is
B67.61 identifies infection with Echinococcus multilocularis affecting multiple sites. Use it when documentation shows alveolar echinococcosis with involvement beyond a single organ or location.
Clinical signs
Clinical features vary; refer to documentation. Reported findings may include mass-like lesions, organ enlargement, or symptoms related to the affected sites, often discovered on imaging or pathology.
When to use this code
Use this code when the provider documents Echinococcus multilocularis infection involving more than one site, such as liver disease with additional spread to another organ or tissue. Apply it only when the record clearly supports multiple-site involvement. Check documentation if the extent is not specified.
Do not use for
Do not use this code for unspecified echinococcosis, single-site disease, or infections caused by other Echinococcus species. If the note does not confirm multilocularis or multiple sites, code more specifically or check documentation.
Coding tip
Confirm both the organism and the number of involved sites before assigning B67.61.
