ICD-10 Code I69.392 – Facial weakness following cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.392 – Facial weakness following cerebral infarction
What it is
This code identifies facial weakness that remains after a cerebral infarction, meaning a stroke has caused lasting impairment of facial movement. It is a sequela code, so you use it for a residual effect rather than the acute stroke itself.
Clinical signs
Typical findings include drooping or reduced movement on one side of the face, often with impaired smile, eye closure, or facial symmetry. Clinical features vary; refer to documentation.
When to use this code
Use I69.392 when the record clearly states facial weakness is a late effect of a prior cerebral infarction. It fits follow-up visits where the stroke is no longer acute, but the facial deficit remains documented. You may need additional codes for other residual deficits if they are separately documented.
Do not use for
Do not use this code for acute stroke, transient facial weakness, or facial palsy from another cause. Check documentation if the weakness is due to Bell palsy, trauma, surgery, or an unspecified neurologic condition.
Coding tip
Link the residual facial weakness to the prior infarction in the note, because sequela coding depends on that documented relationship.
