ICD-10 Code I69.018 – Other symptoms and signs involving cognitive functions following nontraumatic subarachnoid hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.018 – Other symptoms and signs involving cognitive functions following nontraumatic subarachnoid hemorrhage
What it is
This code identifies residual cognitive-related symptoms after a nontraumatic subarachnoid hemorrhage. Use it for ongoing neurologic effects that remain after the acute bleed has resolved.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may describe memory problems, slowed thinking, impaired attention, or other cognitive changes attributed to the prior hemorrhage.
When to use this code
Use I69.018 when the provider documents cognitive symptoms as a sequela of a nontraumatic subarachnoid hemorrhage. The condition should be linked to the prior hemorrhage, not coded as an acute event. If the note only says “history of SAH” without residual deficits, check documentation.
Do not use for
Do not use this code for acute subarachnoid hemorrhage or for cognitive symptoms without a documented connection to the hemorrhage. If the deficit is due to another neurologic condition, choose the more specific code.
Coding tip
Always verify that the residual cognitive issue is documented as a sequela of nontraumatic subarachnoid hemorrhage before assigning I69.018.
