ICD-10 Code G96 – Other disorders of central nervous system (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G96 – Other disorders of central nervous system
What it is
G96 covers disorders affecting the central nervous system that do not fit a more specific ICD-10-CM diagnosis. Use it when documentation describes a CNS condition, but the exact disorder is not named.
Clinical signs
Clinical features vary; refer to documentation. Findings may include neurologic symptoms such as headache, weakness, sensory changes, or other central nervous system dysfunction, depending on the underlying disorder.
When to use this code
Use G96 when the provider documents a central nervous system disorder without a more specific code available. It is appropriate for nonspecific or miscellaneous CNS conditions that are clearly central nervous system related. Check the record for the exact diagnosis before assigning this code.
Do not use for
Do not use G96 if the chart supports a more specific nervous system diagnosis. It is also wrong for peripheral nerve, muscle, or spinal conditions that are not central nervous system disorders.
Coding tip
Code the most specific CNS diagnosis documented; use G96 only when the record remains nonspecific after review.
