ICD-10 Code I69.032 – Monoplegia of upper limb following nontraumatic subarachnoid hemorrhage affecting left dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.032 – Monoplegia of upper limb following nontraumatic subarachnoid hemorrhage affecting left dominant side
What it is
This code identifies one-sided paralysis or severe weakness of the upper limb that remains after a nontraumatic subarachnoid hemorrhage. It applies when the affected side is the left dominant arm.
Clinical signs
Typical findings include marked loss of voluntary movement, weakness, and impaired arm function on the left dominant side. Clinical features vary; refer to documentation for the exact neurologic deficits and dominance.
When to use this code
Use this code when the record clearly links the upper-limb monoplegia to a prior nontraumatic subarachnoid hemorrhage. The documentation should also specify that the left side is dominant.
Choose it for residual neurologic deficits, not for the acute hemorrhage itself. If laterality, dominance, or the causal relationship is unclear, check documentation before coding.
Do not use for
Do not use this code for acute subarachnoid hemorrhage or for weakness without documented paralysis. It is also incorrect if the affected side or dominance is not confirmed.
Coding tip
Verify that the provider documents both the residual monoplegia and the prior nontraumatic subarachnoid hemorrhage, plus left-dominant laterality, before assigning I69.032.
