ICD-10 Code B69 – Cysticercosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B69 – Cysticercosis
What it is
Cysticercosis is an infection caused by the larval form of Taenia solium. It may affect muscle, eye, skin, or the central nervous system, depending on where the cysts develop.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include seizures, headaches, focal neurologic deficits, or signs of tissue cysts on imaging or examination.
When to use this code
Use B69 when the provider documents cysticercosis as the diagnosis, including neurocysticercosis or infection in other tissues. Code it when imaging, pathology, or clinical assessment supports the condition and the record identifies cysticercosis specifically.
If the note only mentions exposure, suspected infection, or a different parasitic disease, do not assign this code. Check documentation for the involved site and whether the diagnosis is confirmed.
Do not use for
Do not use B69 for taeniasis, nonspecific parasitic infection, or mere carrier status. If the chart does not confirm cysticercosis, check documentation before coding.
Coding tip
Confirm the provider’s stated site and whether the infection is active or historical before assigning B69.
