ICD-10 Code B69.1 – Cysticercosis of eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B69.1 – Cysticercosis of eye
What it is
B69.1 identifies cysticercosis involving the eye, an infection caused by larval Taenia solium in ocular tissues. Use it when documentation specifies ocular involvement, not just systemic or intestinal disease.
Clinical signs
Clinical features vary; refer to documentation. Reported findings may include visual disturbance, eye pain, inflammation, or reduced vision when the parasite affects ocular structures.
When to use this code
Use B69.1 when the provider documents cysticercosis of the eye, ocular cysticercosis, or a confirmed parasite in the eye. It is appropriate for outpatient, inpatient, or consult notes that clearly localize the infection to ocular tissue.
If the record only states cysticercosis without an eye site, you need more specificity before assigning this code. Check documentation for whether the eye is the affected site or whether another organ is involved.
Do not use for
Do not use this code for intestinal tapeworm infection, neurocysticercosis, or unspecified cysticercosis. Avoid it when eye involvement is not documented.
Coding tip
Code B69.1 only when the chart explicitly links cysticercosis to the eye; otherwise, query for the anatomic site.
