ICD-10 Code I69.811 – Memory deficit following other cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.811 – Memory deficit following other cerebrovascular disease
What it is
This code identifies a documented memory problem that remains after a cerebrovascular disease, such as a prior stroke or other brain blood vessel event. It reflects a residual cognitive deficit, not the acute vascular episode.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record describes impaired recall, forgetfulness, or difficulty learning and retaining information after the cerebrovascular condition.
When to use this code
Use this code when the provider documents memory deficit as a residual effect of a previous cerebrovascular disease. It is appropriate for follow-up visits where the acute event is no longer the focus and the ongoing memory problem is being addressed. Code the residual condition when clearly linked in the chart.
Do not use for
Do not use this code for acute stroke, transient ischemic attack, or unspecified cognitive complaints without a documented cerebrovascular cause. Check documentation if the memory issue is better explained by dementia, delirium, or another diagnosis.
Coding tip
Verify that the provider explicitly connects the memory deficit to prior cerebrovascular disease before assigning I69.811.
