ICD-10 Code I69.819 – Unspecified symptoms and signs involving cognitive functions following other cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.819 – Unspecified symptoms and signs involving cognitive functions following other cerebrovascular disease
What it is
This code identifies cognitive problems that occur after a cerebrovascular disease, such as impaired memory, attention, or thinking, when the documentation does not specify the exact symptom. It is a sequela code, so the current issue is linked to a prior cerebrovascular condition.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include confusion, slowed thinking, memory loss, or difficulty with concentration after a stroke or other cerebrovascular event.
When to use this code
Use this code when the provider documents cognitive symptoms or signs as a late effect of a previous cerebrovascular disease, but does not name a more specific cognitive deficit. It may apply in follow-up visits, rehabilitation, or problem-list documentation after the acute event has resolved. Confirm that the record links the cognitive issue to the cerebrovascular disease.
Do not use for
Do not use this code for acute stroke symptoms, dementia with a separate documented cause, or cognitive changes unrelated to cerebrovascular disease. Check documentation if the record specifies a more precise post-stroke cognitive diagnosis.
Coding tip
Code the sequela only when the cognitive finding is clearly documented as due to a prior cerebrovascular condition.
