ICD-10 Code I69.85 – Hemiplegia and hemiparesis following other cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.85 – Hemiplegia and hemiparesis following other cerebrovascular disease
What it is
I69.85 identifies hemiplegia or hemiparesis that remains after a prior cerebrovascular disease other than stroke categories with more specific codes. It reflects a lasting unilateral weakness or paralysis due to an old brain vascular event.
Clinical signs
Typical findings include weakness or paralysis on one side of the body, often with impaired gait, arm use, or facial movement. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly links current hemiplegia or hemiparesis to a past cerebrovascular disease. The condition should be residual, not acute, and documented as following the prior event. If the type of cerebrovascular disease is unspecified, check documentation before coding.
Do not use for
Do not use this code for acute stroke, transient ischemic attack, or weakness without a documented cerebrovascular cause. Check documentation if the residual deficit is not clearly tied to a prior event.
Coding tip
Look for provider wording such as “late effect,” “residual,” or “due to prior cerebrovascular disease” before assigning I69.85.
