ICD-10 Code I69.044 – Monoplegia of lower limb following nontraumatic subarachnoid hemorrhage affecting left non-dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.044 – Monoplegia of lower limb following nontraumatic subarachnoid hemorrhage affecting left non-dominant side
What it is
This code identifies a persistent paralysis or severe weakness limited to one lower limb after a nontraumatic subarachnoid hemorrhage. It specifies the left side and that the patient is left non-dominant, which affects code selection.
Clinical signs
Typical findings include marked loss of voluntary movement in one leg, with reduced strength and impaired walking or standing. Clinical features vary; refer to documentation for laterality, dominance, and whether the deficit follows the hemorrhagic event.
When to use this code
Use this code when the record clearly links the monoplegia to a prior nontraumatic subarachnoid hemorrhage and documents the affected lower limb. You should also confirm the left side and non-dominant status in the chart. If the cause or side is unclear, check documentation.
Do not use for
Do not use this code for monoplegia from trauma, stroke without documented subarachnoid hemorrhage, or weakness that is not specifically described as monoplegia. Do not assign it if laterality or dominance is not supported in the record.
Coding tip
Verify the residual deficit and the original hemorrhage relationship before coding, and code the exact side only when the documentation supports it.
