ICD-10 Code I69.839 – Monoplegia of upper limb following other cerebrovascular disease affecting unspecified side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.839 – Monoplegia of upper limb following other cerebrovascular disease affecting unspecified side
What it is
I69.839 identifies one-sided paralysis or severe weakness of an upper limb that occurs after a cerebrovascular disease other than stroke types specifically named elsewhere. The affected side is not documented.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you will see reduced or absent voluntary movement in one arm, with weakness, poor coordination, or functional limitation after a prior cerebrovascular event.
When to use this code
Use this code when the record clearly links monoplegia of an upper limb to a past cerebrovascular disease and the side is not specified. It is appropriate for residual deficits, not the acute event itself. Check documentation for the exact cerebrovascular cause and laterality.
Do not use for
Do not use this code for acute stroke, transient ischemic attack, or hemiplegia affecting both arm and leg. If the side is documented, choose the more specific code.
Coding tip
Confirm the residual deficit, the prior cerebrovascular condition, and whether laterality is unspecified before assigning I69.839.
