ICD-10 Code B70.1 – Sparganosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B70.1 – Sparganosis
What it is
B70.1 identifies sparganosis, a parasitic infection caused by the larval stage of Spirometra tapeworms. It usually involves tissue invasion outside the intestine, so you code the confirmed diagnosis when documented.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include a slowly moving subcutaneous mass, swelling, or symptoms from tissue migration, and diagnosis is often supported by parasite identification or pathology.
When to use this code
Use B70.1 when the record clearly documents sparganosis or infection by Spirometra larvae. Apply it for confirmed parasitic disease, whether identified clinically, surgically, or by pathology. If the note only says “parasite exposure” or “possible worm infection,” check documentation before coding.
Do not use for
Do not use this code for nonspecific abdominal pain, cysts, or masses without a documented parasitic cause. Also avoid it when the provider documents another helminth infection instead of sparganosis.
Coding tip
Look for the exact organism name or a confirmed diagnosis statement before assigning B70.1.
