ICD-10 Code I69.893 – Ataxia following other cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.893 – Ataxia following other cerebrovascular disease
What it is
This code identifies ataxia that remains after a cerebrovascular disease other than a current stroke. It reflects impaired coordination, not the underlying vascular event itself.
Clinical signs
Typical findings include unsteady gait, poor balance, and difficulty with coordinated movements. Clinical features vary; refer to documentation.
When to use this code
Use I69.893 when the record clearly links ataxia to a past cerebrovascular disease and the condition is being managed as a residual effect. You should have documentation showing the ataxia is sequelae, not an acute neurologic event. If the provider does not specify the relationship, check documentation.
Do not use for
Do not use this code for acute stroke, transient symptoms, or ataxia from non-cerebrovascular causes. Do not assign it if the chart does not support a residual neurologic deficit.
Coding tip
Code the residual ataxia only when the provider documents it as a sequela of cerebrovascular disease.
