ICD-10 Code I69.053 – Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage affecting right non-dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.053 – Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage affecting right non-dominant side
What it is
This code identifies persistent weakness or paralysis on the right, non-dominant side after a nontraumatic subarachnoid hemorrhage. It is used for a late effect, not the acute bleed.
Clinical signs
Look for documented hemiplegia or hemiparesis with right-sided motor deficit and a history of subarachnoid hemorrhage. Clinical features vary; refer to documentation for dominance and laterality.
When to use this code
Use I69.053 when the record clearly states residual right-sided weakness due to a prior nontraumatic subarachnoid hemorrhage. You should code it for ongoing neurologic deficits after the acute event has resolved. Confirm that the right side is non-dominant and that the deficit is a sequela.
Do not use for
Do not use this code for the acute subarachnoid hemorrhage itself or for weakness from another cause. Check documentation if laterality, dominance, or the relationship to the hemorrhage is unclear.
Coding tip
Verify sequela wording and side dominance in the note before assigning I69.053.
