ICD-10 Code I69.35 – Hemiplegia and hemiparesis following cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.35 – Hemiplegia and hemiparesis following cerebral infarction
What it is
I69.35 identifies weakness or paralysis affecting one side of the body that remains after a cerebral infarction, or ischemic stroke. Use it for residual deficits from the prior stroke, not the acute event.
Clinical signs
Typical findings include unilateral arm or leg weakness, reduced motor control, and abnormal gait or arm swing. Clinical features vary; refer to documentation for the affected side and whether hemiplegia or hemiparesis is documented.
When to use this code
Use this code when the record states persistent hemiplegia or hemiparesis due to a previous cerebral infarction. It is appropriate for follow-up visits, rehabilitation, or ongoing management after the acute stroke phase. Code the residual deficit only when the provider links it to the infarction.
Do not use for
Do not use I69.35 for the acute cerebrovascular accident or for weakness with no documented stroke cause. Check documentation if the deficit is from another neurologic condition or if the stroke type is unspecified.
Coding tip
Always verify that the provider documents both the residual weakness and its cause as a prior cerebral infarction.
