ICD-10 Code I69.243 – Monoplegia of lower limb following other nontraumatic intracranial hemorrhage affecting right non-dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.243 – Monoplegia of lower limb following other nontraumatic intracranial hemorrhage affecting right non-dominant side
What it is
This code identifies lasting weakness or paralysis limited to one lower limb after a nontraumatic intracranial hemorrhage. The right leg is affected, and the patient is documented as having right non-dominant side involvement.
Clinical signs
Typical findings include reduced voluntary movement, abnormal gait, or inability to use the affected leg normally after the hemorrhagic event. Clinical features vary; refer to documentation.
When to use this code
Use I69.243 when the record clearly links the monoplegia to a prior nontraumatic intracranial hemorrhage and specifies the right non-dominant lower limb. Code the residual deficit, not the acute bleed, when the hemorrhage is no longer the active reason for care.
Do not use for
Do not use this code for acute intracranial hemorrhage, weakness without documented monoplegia, or paralysis from another cause. Check documentation if laterality, dominance, or the causal hemorrhage type is unclear.
Coding tip
Confirm the residual deficit and the exact side before assigning this code.
