ICD-10 Code I69.242 – Monoplegia of lower limb following other nontraumatic intracranial hemorrhage affecting left dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.242 – Monoplegia of lower limb following other nontraumatic intracranial hemorrhage affecting left dominant side
What it is
This code identifies paralysis affecting one lower limb after a nontraumatic intracranial hemorrhage. It applies when the weakness or loss of movement is on the left dominant side and is a late effect of the bleed.
Clinical signs
Typical findings include marked weakness or complete loss of voluntary movement in one leg, with functional impairment in walking or standing. Clinical features vary; refer to documentation.
When to use this code
Use I69.242 when the record clearly links the monoplegia to a prior nontraumatic intracranial hemorrhage and specifies the left dominant lower limb. The condition should be documented as a sequela, not an acute stroke event.
Code it when the provider describes persistent post-hemorrhagic motor deficit affecting only one lower extremity. Check documentation if laterality, dominance, or the hemorrhage type is unclear.
Do not use for
Do not use this code for acute intracranial hemorrhage, generalized weakness, or paralysis from trauma. Check documentation if the deficit involves more than one limb or if the affected side is not specified.
Coding tip
Confirm both the sequela relationship and the dominant-side laterality before assigning this code.
