ICD-10 Code I69.019 – Unspecified symptoms and signs involving cognitive functions following nontraumatic subarachnoid hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.019 – Unspecified symptoms and signs involving cognitive functions following nontraumatic subarachnoid hemorrhage
What it is
This code identifies unspecified cognitive symptoms that persist after a nontraumatic subarachnoid hemorrhage. Use it when the record links ongoing cognitive problems to that prior hemorrhage but does not name a more specific deficit.
Clinical signs
Clinical features may include memory problems, slowed thinking, or reduced attention after recovery from the bleed. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents residual cognitive impairment after a nontraumatic subarachnoid hemorrhage and does not specify aphasia, apraxia, or another defined deficit. It also fits follow-up encounters for sequelae when the cognitive issue remains the active reason for care.
Confirm that the cognitive symptom is a late effect of the hemorrhage, not a new neurologic event or an unrelated dementia diagnosis. Check documentation if the record does not clearly connect the symptom to the prior subarachnoid hemorrhage.
Do not use for
Do not use this code for acute subarachnoid hemorrhage or for cognitive symptoms without documented linkage to a past hemorrhage. Do not use it when the chart specifies a different post-stroke cognitive deficit.
Coding tip
Verify the sequela relationship and the nontraumatic subarachnoid hemorrhage history before assigning I69.019.
