ICD-10 Code I69.354 – Hemiplegia and hemiparesis following cerebral infarction affecting left non-dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.354 – Hemiplegia and hemiparesis following cerebral infarction affecting left non-dominant side
What it is
This code identifies residual weakness or paralysis on the left side after a cerebral infarction. It applies when the left side is the non-dominant side, based on the patient’s documented dominance.
Clinical signs
Expected findings include unilateral motor weakness, reduced voluntary movement, and possible gait or arm function impairment after stroke. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states hemiplegia or hemiparesis is a late effect of a prior cerebral infarction and specifically affects the left non-dominant side. You should confirm laterality, dominance, and the causal link to the old stroke. If the documentation does not clearly establish these details, check documentation.
Do not use for
Do not use this code for acute stroke, transient ischemic attack, or weakness without a documented infarction history. It is also wrong for left-sided deficits when dominance is not documented or when another neurologic cause is recorded.
Coding tip
Link the residual deficit to the prior infarction in the chart and verify the affected side before assigning I69.354.
