ICD-10 Code A17.1 – Meningeal tuberculoma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A17.1 – Meningeal tuberculoma
What it is
A17.1 identifies tuberculous infection involving the meninges, usually as a localized tuberculoma. It reflects central nervous system tuberculosis affecting the protective membranes around the brain or spinal cord.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include headache, fever, neck stiffness, altered mental status, or focal neurologic deficits when the meninges are involved.
When to use this code
Use A17.1 when the record clearly documents meningeal tuberculoma or tuberculous meningitis/tuberculous meningeal involvement. Code it only when the provider links the condition to tuberculosis and the site is the meninges. Check documentation if the note describes CNS TB without meningeal involvement.
Do not use for
Do not use this code for pulmonary tuberculosis, latent TB, or nonmeningeal tuberculoma. If the chart does not confirm meningeal involvement, check documentation and code the documented condition instead.
Coding tip
Assign the code only when the provider documents meningeal TB specifically; otherwise, query for the exact CNS site.
