ICD-10 Code I69.815 – Cognitive social or emotional deficit following other cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.815 – Cognitive social or emotional deficit following other cerebrovascular disease
What it is
This code identifies cognitive, social, or emotional problems that persist after a cerebrovascular disease other than stroke. Use it when the deficit is documented as a late effect of that vascular condition.
Clinical signs
Clinical features may include impaired judgment, reduced social awareness, emotional lability, or difficulty with interaction after the cerebrovascular event. Clinical features vary; refer to documentation.
When to use this code
Use I69.815 when the record clearly links the ongoing cognitive, social, or emotional deficit to a prior cerebrovascular disease. It is appropriate for follow-up visits where the residual deficit is the reason for care or is still being monitored. If the documentation does not specify the type of deficit, check documentation.
Do not use for
Do not use this code for acute cerebrovascular disease or for deficits not documented as residual effects. Do not assign it when the chart only describes general neurological impairment without a clear cognitive, social, or emotional component.
Coding tip
Look for explicit wording such as “due to,” “late effect,” or “residual” to support the causal link before coding.
