ICD-10 Code I69.05 – Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.05 – Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage
What it is
I69.05 reports weakness or paralysis affecting one side of the body that remains after a nontraumatic subarachnoid hemorrhage. Use it for residual neurologic deficits, not the acute bleed itself.
Clinical signs
Typical findings include unilateral weakness, reduced motor control, or partial paralysis documented after recovery from the hemorrhage. Clinical features vary; refer to documentation.
When to use this code
Use this code when the chart clearly links current hemiplegia or hemiparesis to a prior nontraumatic subarachnoid hemorrhage. It fits follow-up visits, rehabilitation, and ongoing neurologic care. Code the residual deficit when it is still present and documented.
Do not use for
Do not use it for the acute subarachnoid hemorrhage itself or for weakness with no documented cause. Check documentation if the record does not clearly state a post-hemorrhagic residual.
Coding tip
Look for provider wording that explicitly connects the weakness to the prior subarachnoid hemorrhage before assigning I69.05.
