ICD-10 Code I69.01 – Cognitive deficits following nontraumatic subarachnoid hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.01 – Cognitive deficits following nontraumatic subarachnoid hemorrhage
What it is
This code identifies cognitive impairment that remains after a nontraumatic subarachnoid hemorrhage. Use it when the record links memory, attention, or executive problems to that prior hemorrhagic stroke.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded deficits include reduced short-term memory, slowed thinking, poor concentration, or impaired problem solving after the hemorrhage.
When to use this code
Use I69.01 when the provider documents cognitive deficits as a late effect of a nontraumatic subarachnoid hemorrhage. It applies to ongoing sequelae, not the acute bleed itself. Code the residual condition when the relationship is clearly stated or implied in the chart.
Do not use for
Do not use this code for the acute subarachnoid hemorrhage, traumatic brain injury, or cognitive decline from another cause. Check documentation if the cause of the cognitive problem is not clearly linked to the hemorrhage.
Coding tip
Confirm the note describes a residual deficit after the hemorrhage, because sequela codes require the underlying event and the lasting condition to be documented.
