ICD-10 Code G98.0 – Neurogenic arthritis, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G98.0 – Neurogenic arthritis, not elsewhere classified
What it is
G98.0 identifies neurogenic arthritis, a joint disorder caused by impaired nerve supply rather than primary joint disease. Use it when documentation specifically names neurogenic arthritis and does not identify a more specific underlying neurologic condition.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include joint destruction, instability, swelling, deformity, and reduced sensation or pain perception around the affected joint.
When to use this code
Use G98.0 when the provider documents neurogenic arthritis or Charcot-type arthropathy without assigning a different more specific code. It may appear in records describing neuropathic joint changes linked to loss of protective sensation. Check documentation for the underlying neurologic cause and whether an additional code is needed.
Do not use for
Do not use this code for ordinary osteoarthritis, rheumatoid arthritis, or traumatic joint injury. If the record does not clearly support a neurogenic cause, check documentation before coding.
Coding tip
Verify the exact provider wording and code any documented underlying neurologic disorder separately when required.
