ICD-10 Code B69.0 – Cysticercosis of Central Nervous System (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B69.0 – Cysticercosis of central nervous system
What it is
B69.0 identifies cysticercosis affecting the central nervous system, usually when Taenia solium larvae form cysts in the brain or spinal cord. Use it for neurocysticercosis when documentation specifies central nervous system involvement.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include seizures, headaches, focal neurologic deficits, hydrocephalus, or signs of increased intracranial pressure, often supported by imaging or other neurologic evaluation.
When to use this code
Use B69.0 when the provider documents cysticercosis or neurocysticercosis involving the brain, meninges, or spinal cord. It is appropriate when the record clearly links the parasitic infection to central nervous system disease. If the site is not specified, check documentation before assigning this code.
Do not use for
Do not use B69.0 for intestinal taeniasis, generalized cysticercosis without CNS involvement, or an unspecified parasitic infection. If the documentation only says “cysticercosis” without location, check documentation.
Coding tip
Confirm the anatomic site and whether the provider documents CNS involvement before coding B69.0.
