ICD-10 Code I69.23 – Monoplegia of upper limb following other nontraumatic intracranial hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.23 – Monoplegia of upper limb following other nontraumatic intracranial hemorrhage
What it is
I69.23 identifies paralysis affecting one upper limb as a late effect of a prior nontraumatic intracranial hemorrhage, such as a hemorrhagic stroke. Use it when the weakness is a residual condition rather than an acute event.
Clinical signs
Typical findings include persistent loss of voluntary movement or marked weakness in one arm, often with reduced functional use after the hemorrhage. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states monoplegia of an upper limb is due to a previous nontraumatic intracranial hemorrhage and the acute bleed is no longer being treated. It is appropriate for follow-up visits documenting ongoing neurologic deficit. Check documentation for laterality and whether the condition is a sequela.
Do not use for
Do not use it for acute intracranial hemorrhage, transient weakness, or paralysis from trauma. Do not use if the chart does not link the arm monoplegia to a prior nontraumatic intracranial hemorrhage.
Coding tip
Verify that the provider documents a causal relationship to the old hemorrhage before assigning I69.23.
