ICD-10 Code I69.093 – Ataxia following nontraumatic subarachnoid hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.093 – Ataxia following nontraumatic subarachnoid hemorrhage
What it is
This code identifies ataxia that remains after a nontraumatic subarachnoid hemorrhage. It reflects a residual coordination problem due to prior bleeding around the brain, not the acute hemorrhage itself.
Clinical signs
Patients may have unsteady gait, poor balance, or impaired coordination after the hemorrhagic event. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents ataxia as a late effect of a nontraumatic subarachnoid hemorrhage. The hemorrhage should be past history, with the current visit focused on the residual neurologic deficit. If the provider does not clearly link the ataxia to the prior hemorrhage, check documentation.
Do not use for
Do not use this code for acute subarachnoid hemorrhage or for ataxia from another cause. It is also inappropriate when the chart does not specify a nontraumatic hemorrhagic sequela.
Coding tip
Confirm the provider documents a causal relationship between the prior hemorrhage and the ataxia before assigning I69.093.
