ICD-10 Code I69.051 – Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage affecting right dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.051 – Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage affecting right dominant side
What it is
This code identifies persistent weakness or paralysis on the right side after a nontraumatic subarachnoid hemorrhage, in a patient whose right side is dominant. It is a sequela code, so you report the lasting neurologic deficit, not the acute bleed.
Clinical signs
Typical findings include unilateral motor weakness, reduced coordination, abnormal gait, or loss of functional use on the affected side. Clinical features vary; refer to documentation for whether the deficit is hemiplegia or hemiparesis.
When to use this code
Use I69.051 when the record clearly links the current right-sided deficit to a prior nontraumatic subarachnoid hemorrhage and states the dominant side. This is appropriate for follow-up visits, rehabilitation encounters, and long-term neurologic impairment after the acute event has resolved. Check documentation if laterality or dominance is not specified.
Do not use for
Do not use this code for acute subarachnoid hemorrhage, traumatic intracranial bleeding, or weakness from another cause. Do not assign it if the chart does not document a residual deficit after the hemorrhage.
Coding tip
Code the residual neurologic deficit first when the acute hemorrhage is no longer the reason for the encounter, and verify dominant-side documentation before assigning I69.051.
