ICD-10 Code I69.318 – Other symptoms and signs involving cognitive functions following cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.318 – Other symptoms and signs involving cognitive functions following cerebral infarction
What it is
This code identifies residual cognitive problems that remain after a cerebral infarction, such as impaired attention, memory, or executive function. It is used when the cognitive issue is a late effect of the stroke.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include slowed thinking, poor concentration, memory loss, or difficulty with planning and judgment after an ischemic stroke.
When to use this code
Use this code when the record clearly links ongoing cognitive symptoms to a prior cerebral infarction. It fits follow-up visits, rehabilitation care, or problem lists describing persistent post-stroke cognitive deficits. Check documentation if the provider does not specify the relationship to the infarction.
Do not use for
Do not use it for cognitive symptoms without a documented history of cerebral infarction, or when the deficit is due to another neurologic condition. Do not assign it if the provider documents a different post-stroke deficit more specifically.
Coding tip
Make sure the note states both the prior infarction and the ongoing cognitive sequelae before you code I69.318.
