ICD-10 Code I69.311 – Memory deficit following cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.311 – Memory deficit following cerebral infarction
What it is
I69.311 identifies a memory deficit that remains after a cerebral infarction, or ischemic stroke. Use it when the stroke has already occurred and the documented sequela is impaired memory.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include forgetfulness, poor short-term recall, or difficulty learning and retaining new information after stroke.
When to use this code
Use this code when the provider documents memory loss, amnesia, or memory impairment as a late effect of a prior cerebral infarction. It is appropriate for follow-up visits where the stroke is no longer acute but the memory deficit persists.
Code the sequela rather than the acute stroke when the residual deficit is the reason for the encounter. Check documentation for the relationship between the infarction and the memory problem.
Do not use for
Do not use this code for acute stroke symptoms without a documented residual memory deficit. Do not use it when memory problems are unrelated to cerebral infarction; check documentation.
Coding tip
Link the memory deficit to the prior infarction in the medical record before assigning I69.311.
