ICD-10 Code I69.31 – Cognitive deficits following cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.31 – Cognitive deficits following cerebral infarction
What it is
This code identifies cognitive problems that remain after a cerebral infarction, or ischemic stroke. Use it when the record shows memory, attention, or thinking deficits attributed to the prior infarct.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include impaired memory, slowed processing, poor attention, or difficulty with executive function after stroke.
When to use this code
Use I69.31 when the provider documents cognitive deficits as a late effect of a prior cerebral infarction. It is appropriate for follow-up visits where the stroke is no longer acute but cognitive sequelae remain. Confirm that the deficit is linked to the infarction, not another neurologic or psychiatric cause.
Do not use for
Do not use this code for acute stroke, transient ischemic attack, or unspecified cognitive impairment without a documented stroke cause. Check documentation if the cognitive change is due to another condition.
Coding tip
Code the residual cognitive deficit and the history of stroke only as supported by the note.
