ICD-10 Code I69.352 – Hemiplegia and Hemiparesis Following Cerebral Infarction Affecting Left Dominant Side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.352 – Hemiplegia and hemiparesis following cerebral infarction affecting left dominant side
What it is
This code identifies weakness or paralysis on the left side that remains after a cerebral infarction, in a patient whose left side is dominant. It reflects a late effect of stroke, not the acute infarction itself.
Clinical signs
Typical findings include persistent unilateral weakness, reduced motor control, abnormal gait, or impaired use of the left arm and leg. Clinical features vary; refer to documentation for dominance and the post-stroke residual deficit.
When to use this code
Use I69.352 when the record clearly states hemiplegia or hemiparesis as a residual condition after cerebral infarction. You should code it when the provider documents left-side dominance and links the deficit to a prior stroke. Check documentation if laterality or dominance is unclear.
Do not use for
Do not use this code for acute cerebral infarction, transient weakness, or hemiplegia from another cause. It is also incorrect if the chart does not specify a post-infarction residual or left dominant side.
Coding tip
Confirm the stroke is historical and the weakness is residual, then match laterality and dominance exactly to the provider’s documentation.
