ICD-10 Code I69.231 – Monoplegia of upper limb following other nontraumatic intracranial hemorrhage affecting right dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.231 – Monoplegia of upper limb following other nontraumatic intracranial hemorrhage affecting right dominant side
What it is
This code identifies one-sided paralysis or severe weakness of the right upper limb caused by a prior nontraumatic intracranial hemorrhage. It also specifies that the affected side is the dominant side.
Clinical signs
Typical findings include marked loss of voluntary movement, reduced strength, and impaired use of the right arm after a documented brain bleed. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly links the upper-limb monoplegia to a past nontraumatic intracranial hemorrhage and identifies the right dominant side. You should code it for residual deficits, not for the acute hemorrhage itself. Check documentation if the side, dominance, or cause is not stated.
Do not use for
Do not use this code for acute intracranial hemorrhage, generalized hemiplegia, or weakness without a documented neurologic deficit from hemorrhage. If the cause is traumatic or unspecified, choose a different code.
Coding tip
Confirm the residual deficit, laterality, dominance, and hemorrhage type in the provider note before assigning I69.231.
