ICD-10 Code I69.059 – Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage affecting unspecified side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.059 – Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage affecting unspecified side
What it is
This code identifies residual weakness or paralysis affecting one side of the body after a nontraumatic subarachnoid hemorrhage. Use it when the affected side is not documented.
Clinical signs
Typical findings include unilateral weakness, reduced motor control, and impaired movement after recovery from the hemorrhage. Clinical features vary; refer to documentation.
When to use this code
Use I69.059 when the record clearly links hemiplegia or hemiparesis to a prior nontraumatic subarachnoid hemorrhage and no side is specified. It applies to ongoing sequelae, not the acute bleed. If laterality is documented, choose the more specific code.
Do not use for
Do not use this code for acute subarachnoid hemorrhage, traumatic intracranial injury, or weakness without a documented stroke-related cause. Check documentation.
Coding tip
Confirm both the prior hemorrhage and the residual motor deficit before assigning the sequela code.
