ICD-10 Code B67.90 – Echinococcosis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B67.90 – Echinococcosis, unspecified
What it is
B67.90 identifies echinococcosis when the species or specific organ site is not documented. Use it for hydatid disease caused by Echinococcus infection when the record does not provide more detail.
Clinical signs
Clinical features vary; refer to documentation. Patients may have symptoms related to cysts or mass effect, but the exact presentation depends on the involved organ and extent of disease.
When to use this code
Use B67.90 when the clinician documents echinococcosis or hydatid disease without naming the species or location. It also fits when the chart confirms infection, but the available note is too nonspecific for a more detailed code.
If later documentation identifies the organ involved or the specific form, code to that more precise option instead. Check documentation for imaging, pathology, or provider assessment supporting the diagnosis.
Do not use for
Do not use this code when the record specifies a particular echinococcosis site or species. Also avoid it if echinococcal disease is only suspected and not confirmed.
Coding tip
Query for the organ involved or species whenever possible, because B67.90 is the least specific option.
