ICD-10 Code G96.89 – Other specified disorders of central nervous system (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G96.89 – Other specified disorders of central nervous system
What it is
G96.89 is used for a central nervous system disorder that is documented but does not fit a more specific ICD-10-CM code. It identifies an otherwise specified condition involving the brain, spinal cord, or related CNS structures.
Clinical signs
Clinical features vary; refer to documentation. Findings may reflect neurologic dysfunction, but the record must support a specific CNS disorder that is not classified elsewhere.
When to use this code
Use G96.89 when the provider names a central nervous system disorder and no more precise code is available. It is appropriate when the note clearly states “other specified” or gives a diagnosis that does not map to a defined category. Check documentation to confirm the condition is not better coded elsewhere.
Do not use for
Do not use this code when a more specific CNS diagnosis is documented and coded elsewhere. Do not use it for unspecified neurologic symptoms without a confirmed disorder.
Coding tip
Before assigning G96.89, verify that the provider’s wording supports a specified CNS disorder and that no narrower code applies.
