ICD-10 Code B67.1 – Echinococcus granulosus infection of lung (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B67.1 – Echinococcus granulosus infection of lung
What it is
B67.1 identifies hydatid disease of the lung caused by Echinococcus granulosus. It is used when the parasite forms a cyst or other lung involvement, not for unrelated pulmonary infections.
Clinical signs
Clinical features vary; refer to documentation. Patients may have cough, chest discomfort, dyspnea, or an incidental lung cyst on imaging. Diagnosis is usually supported by imaging and clinical assessment.
When to use this code
Use B67.1 when the provider documents Echinococcus granulosus infection involving the lung, pulmonary hydatid cyst, or lung echinococcosis. Code it from confirmed documentation, imaging, or operative findings when the lung is the specified site. Check documentation if the record only says echinococcosis without location.
Do not use for
Do not use this code for liver, brain, or other organ involvement. Do not assign it for suspected exposure, screening, or nonspecific pulmonary cysts without documented Echinococcus granulosus infection.
Coding tip
Capture the exact anatomic site and organism name; if the note is vague, query the provider before coding.
