ICD-10 Code I69.149 – Monoplegia of lower limb following nontraumatic intracerebral hemorrhage affecting unspecified side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.149 – Monoplegia of lower limb following nontraumatic intracerebral hemorrhage affecting unspecified side
What it is
This code identifies weakness or paralysis affecting one lower limb after a nontraumatic intracerebral hemorrhage, when the affected side is not documented. It is a late effect code used for residual deficits after the stroke event.
Clinical signs
Typical findings include persistent loss of strength, poor leg control, or inability to move one leg after a documented intracerebral hemorrhage. Clinical features vary; refer to documentation.
When to use this code
Use I69.149 when the chart clearly links the current monoplegia to a prior nontraumatic intracerebral hemorrhage and the lower limb side is unspecified. It may apply in follow-up, rehabilitation, or chronic care notes. Confirm that the hemorrhage is the cause of the residual deficit.
Do not use for
Do not use this code for acute intracerebral hemorrhage without a residual deficit, or when the monoplegia is from trauma or another neurologic cause. Check documentation if the side is stated elsewhere.
Coding tip
Sequence the residual deficit code only when the provider documents it as a sequela of the prior hemorrhage.
