ICD-10 Code I69.83 – Monoplegia of Upper Limb Following Other Cerebrovascular Disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.83 – Monoplegia of upper limb following other cerebrovascular disease
What it is
I69.83 identifies upper-limb monoplegia that remains after a cerebrovascular disease other than stroke. It means one arm has persistent paralysis or severe weakness due to prior brain or vascular injury.
Clinical signs
Typical findings include marked loss of voluntary movement in one upper limb, with reduced strength and impaired function. Clinical features vary; refer to documentation, especially for the underlying cerebrovascular disease and laterality if stated.
When to use this code
Use this code when the record documents residual monoplegia of an arm after a prior cerebrovascular event or disease process. It is appropriate for ongoing deficits in the recovery phase, not for the acute event itself. You should code the residual condition when it is the focus of care or still affects function.
Do not use for
Do not use it for acute stroke, transient weakness, or generalized hemiplegia. Check documentation if the deficit is better described by another sequela code or if the cause is not a cerebrovascular disease.
Coding tip
Link the residual arm deficit to the prior cerebrovascular condition in the note before assigning I69.83.
