ICD-10 Code I69.363 – Other paralytic syndrome following cerebral infarction affecting right non-dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.363 – Other paralytic syndrome following cerebral infarction affecting right non-dominant side
What it is
I69.363 identifies a residual paralytic syndrome that remains after a cerebral infarction and affects the right non-dominant side. Use it for ongoing neurologic weakness or paralysis documented as a late effect of stroke.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include persistent weakness, paralysis, or impaired motor control on the right side after a prior cerebral infarction, with the right side designated as non-dominant.
When to use this code
Use this code when the provider documents a paralytic condition that is a sequela of a previous cerebral infarction and specifies the right non-dominant side. It is appropriate for follow-up visits where the stroke is no longer acute but the deficit remains. Check documentation if laterality, dominance, or the exact residual deficit is unclear.
Do not use for
Do not use this code for acute stroke, transient neurologic symptoms, or weakness without a documented post-infarction paralytic syndrome. If the side is dominant or the residual effect is different, choose the documented code instead.
Coding tip
Verify that the record links the paralysis to a prior cerebral infarction and confirms the right side is non-dominant before assigning I69.363.
