ICD-10 Code I69.052 – Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage affecting left dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.052 – Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage affecting left dominant side
What it is
This code identifies residual weakness or paralysis on the left dominant side after a nontraumatic subarachnoid hemorrhage. Use it for a post-stroke neurologic deficit, not the acute bleed itself.
Clinical signs
Findings usually include decreased strength, abnormal gait, or impaired use of the left side. Clinical features vary; refer to documentation for dominance, laterality, and whether the deficit is hemiplegia or hemiparesis.
When to use this code
Use I69.052 when the record documents ongoing left-sided hemiplegia or hemiparesis as a sequela of a prior nontraumatic subarachnoid hemorrhage. The provider should link the neurologic deficit to the hemorrhage. If the chart does not specify dominant side or laterality, check documentation.
Do not use for
Do not use this code for the acute subarachnoid hemorrhage, traumatic intracranial injury, or weakness without a documented cerebrovascular cause. Check documentation if the residual deficit is unspecified.
Coding tip
Code the residual neurologic deficit first when the encounter is for aftercare or long-term effects of the hemorrhage.
