ICD-10 Code I69.841 – Monoplegia of lower limb following other cerebrovascular disease affecting right dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.841 – Monoplegia of lower limb following other cerebrovascular disease affecting right dominant side
What it is
This code identifies paralysis or severe weakness affecting one lower limb on the right dominant side after a cerebrovascular disease other than stroke. Use it for a residual neurologic deficit, not the original vascular event.
Clinical signs
You may see loss of voluntary movement, marked weakness, abnormal gait, or need for assistive support in the affected leg. Clinical features vary; refer to documentation.
When to use this code
Use I69.841 when the record clearly links the lower-limb monoplegia to a prior cerebrovascular disease and specifies the right dominant side. It is appropriate for ongoing deficits documented as sequelae during follow-up or rehabilitation. Check documentation if laterality, dominance, or the vascular cause is unclear.
Do not use for
Do not use this code for acute stroke, transient weakness, or monoplegia from trauma, spinal cord disease, or peripheral nerve disorders. Check documentation if the residual deficit is not explicitly tied to a cerebrovascular condition.
Coding tip
Confirm the residual deficit and the exact side from the provider’s note before assigning this code.
