ICD-10 Code I69.919 – Unspecified symptoms and signs involving cognitive functions following unspecified cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.919 – Unspecified symptoms and signs involving cognitive functions following unspecified cerebrovascular disease
What it is
This code describes lingering, unspecified cognitive problems after a cerebrovascular disease event. Use it when the record links memory, attention, or other mental-function issues to prior stroke or similar vascular disease, but does not specify the exact deficit.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include reduced memory, slowed thinking, poor attention, or other nonspecific cognitive impairment after a cerebrovascular event.
When to use this code
Use I69.919 when the provider documents cognitive symptoms as a late effect of cerebrovascular disease and does not name a more specific cognitive diagnosis. It is appropriate for follow-up visits addressing persistent mental-function changes after the acute event has passed. You should code the underlying cerebrovascular history separately when required.
Do not use for
Do not use this code for acute stroke, transient ischemic attack, or cognitive symptoms without a documented cerebrovascular cause. Check documentation if the impairment is better described by dementia or another neurologic condition.
Coding tip
Link the cognitive complaint to the prior cerebrovascular disease in the note before assigning this code.
