ICD-10 Code I69.351 – Hemiplegia and hemiparesis following cerebral infarction affecting right dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.351 – Hemiplegia and hemiparesis following cerebral infarction affecting right dominant side
What it is
This code identifies ongoing weakness or paralysis on the right side after a cerebral infarction, in a patient whose right side is dominant. It reflects a late effect of stroke, not the acute stroke event itself.
Clinical signs
Typical findings include persistent unilateral motor weakness, reduced strength, abnormal gait, or impaired arm and leg function on the right. Clinical features vary; refer to documentation.
When to use this code
Use I69.351 when the record clearly states hemiplegia or hemiparesis due to a prior cerebral infarction and specifies the right dominant side. It may appear in follow-up care, rehabilitation, or chronic problem lists after the acute stroke phase. Confirm laterality and dominance in the chart.
Do not use for
Do not use this code for the acute cerebral infarction itself or for weakness with no documented stroke cause. Check documentation if the side, dominance, or stroke relationship is unclear.
Coding tip
Code the residual deficit first, and verify that the provider links it to a prior cerebral infarction.
