ICD-10 Code I69.364 – Other paralytic syndrome following cerebral infarction affecting left non-dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.364 – Other paralytic syndrome following cerebral infarction affecting left non-dominant side
What it is
This code identifies residual paralysis or other paralytic syndrome that remains after a cerebral infarction, affecting the left side in a non-dominant patient. Use it for a post-stroke neurologic deficit that is still present after the acute event.
Clinical signs
Common findings include weakness, loss of motor control, or impaired movement on the left side after a documented cerebral infarction. Clinical features vary; refer to documentation for the exact type and severity of the deficit.
When to use this code
Use this code when the record clearly links the paralysis or other paralytic syndrome to a prior cerebral infarction and specifies the left non-dominant side. It applies to residual deficits during follow-up care, not the acute stroke itself. Confirm laterality and dominance in the chart before assigning it.
Do not use for
Do not use this code for acute ischemic stroke, transient neurologic symptoms, or paralysis from another cause. Check documentation if the side, dominance, or stroke relationship is not clearly stated.
Coding tip
Verify that the provider documents both the post-infarction cause and the left non-dominant side before coding I69.364.
