ICD-10 Code I69.911 – Memory deficit following unspecified cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.911 – Memory deficit following unspecified cerebrovascular disease
What it is
This code identifies memory problems that remain after an unspecified cerebrovascular disease, such as a prior stroke or other brain blood vessel event. Use it when the record links the memory deficit to that past condition.
Clinical signs
Typical findings include short-term memory loss, poor recall, or difficulty remembering recent events. Clinical features vary; refer to documentation.
When to use this code
Use I69.911 when the provider documents memory deficit as a late effect of a prior cerebrovascular disease and the current visit is for that residual problem. This code supports sequela coding after the acute event has resolved. If the chart does not clearly connect the memory deficit to the cerebrovascular disease, check documentation.
Do not use for
Do not use this code for memory loss without a documented cerebrovascular cause, or for acute stroke symptoms. It is also inappropriate when the memory issue is better explained by another neurologic or psychiatric condition.
Coding tip
Confirm the sequela relationship in the note; if the cause is not stated, you should query or check documentation.
