ICD-10 Code B67.9 – Echinococcosis, other and unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B67.9 – Echinococcosis, other and unspecified
What it is
B67.9 identifies echinococcosis when the species or site is not further specified. Use it for hydatid disease documented as other or unspecified, when the record does not support a more exact code.
Clinical signs
Clinical features vary; refer to documentation. Echinococcosis may be found incidentally or present with symptoms related to cysts or mass effect in an involved organ.
When to use this code
Use B67.9 when the provider documents echinococcosis, hydatid disease, or Echinococcus infection without naming the species or exact anatomic site. It is also appropriate when the chart only states “unspecified echinococcosis.”
If a more specific subtype or organ involvement is documented, code that option instead. Check documentation for imaging, pathology, or operative details that identify the site.
Do not use for
Do not use this code when the record identifies a specific echinococcosis code for the organ or species. Do not assign it if the diagnosis is only suspected or ruled out.
Coding tip
Always look for the parasite species and involved organ before defaulting to B67.9.
