ICD-10 Code I69.36 – Other paralytic syndrome following cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.36 – Other paralytic syndrome following cerebral infarction
What it is
This code identifies residual paralysis or weakness that remains after a cerebral infarction, or ischemic stroke. Use it for lasting neurologic deficits, not the acute stroke event.
Clinical signs
Clinical features vary; refer to documentation. Common findings include persistent weakness, impaired movement, or paralysis affecting one or more limbs after a prior cerebral infarction.
When to use this code
Use I69.36 when the chart clearly states a paralytic syndrome is a late effect of a previous cerebral infarction. It fits follow-up visits documenting ongoing hemiparesis, monoplegia, or other residual motor deficit after stroke. Do not use it for the initial stroke admission.
Do not use for
Do not use this code for acute cerebral infarction, transient ischemic attack, or weakness without a documented stroke cause. Check documentation if the residual deficit is not linked to a prior infarction.
Coding tip
Link the residual paralysis to the prior cerebral infarction in the provider’s wording before assigning I69.36.
