ICD-10 Code I69.393 – Ataxia following cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.393 – Ataxia following cerebral infarction
What it is
This code identifies ataxia that remains after a cerebral infarction, or ischemic stroke. It reflects a lasting coordination problem documented as a late effect of the prior stroke.
Clinical signs
Clinical features may include unsteady gait, impaired balance, and poor coordination. You should code it only when the record links the ataxia to a previous cerebral infarction; clinical features vary, refer to documentation.
When to use this code
Use this code when the provider documents ataxia as a sequela of a past cerebral infarction and the acute stroke phase is no longer being treated. It may appear in follow-up, rehabilitation, or long-term neurology care notes. Confirm that the residual deficit is specifically attributed to the infarction.
Do not use for
Do not use this code for ataxia from another cause, such as hereditary, toxic, or cerebellar disorders. Do not use it when the chart does not clearly connect the ataxia to a prior cerebral infarction.
Coding tip
Look for sequela language and the original stroke history; if the relationship is unclear, check documentation.
