ICD-10 Code A17.83 – Tuberculous neuritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A17.83 – Tuberculous neuritis
What it is
A17.83 identifies neuritis caused by tuberculosis infection. Use it when the nerve inflammation is documented as tuberculous and part of active or current TB disease.
Clinical signs
Clinical features vary; refer to documentation. Patients may have focal nerve pain, sensory changes, weakness, or other neurologic deficits consistent with neuritis, with tuberculosis identified as the cause.
When to use this code
Use this code when the record clearly states tuberculous neuritis, tuberculous neuropathy, or nerve inflammation due to TB. It is appropriate when the provider links neurologic findings to tuberculosis rather than to another infectious or inflammatory cause.
If the note only says “neuritis” without a TB connection, check documentation. Code the underlying tuberculosis manifestation as documented and avoid assuming the nerve involvement is tuberculous.
Do not use for
Do not use A17.83 for neuritis from non-tuberculous causes, such as trauma, diabetes, or idiopathic nerve inflammation. Do not use it when tuberculosis is mentioned only as a past history without current causal linkage.
Coding tip
Look for explicit provider wording that ties the neuritis to tuberculosis before assigning A17.83.
