ICD-10 Code B67 – Echinococcosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B67 – Echinococcosis
What it is
B67 identifies echinococcosis, a parasitic infection caused by tapeworm larvae. It usually involves cyst formation in organs such as the liver or lungs.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include an enlarging cystic mass, abdominal pain, cough, or incidental imaging evidence of hydatid disease.
When to use this code
Use B67 when the provider documents echinococcosis, hydatid disease, or infection due to Echinococcus species. Code it when the diagnosis is confirmed or clearly stated in the record, even if the patient is being evaluated for a cystic lesion.
Do not use for
Do not use B67 for an unspecified parasitic infection or for nonparasitic cysts. Check documentation if the record only mentions a suspected mass without confirming echinococcosis.
Coding tip
Review the site and species documented, and assign any additional codes required for the involved organ or complications.
