ICD-10 Code I69.941 – Monoplegia of lower limb following unspecified cerebrovascular disease affecting right dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.941 – Monoplegia of lower limb following unspecified cerebrovascular disease affecting right dominant side
What it is
This code identifies weakness or paralysis limited to the right lower limb after an unspecified cerebrovascular disease. The patient is documented as right-side dominant, which affects code selection.
Clinical signs
Typical findings include reduced voluntary movement, abnormal gait, or inability to lift the affected leg. Clinical features vary; refer to documentation for the specific post-stroke deficit and laterality.
When to use this code
Use this code when the record links a prior unspecified cerebrovascular disease to monoplegia of the right lower limb. It is appropriate for residual deficits after the acute event has passed. Confirm that dominance and laterality are documented.
Do not use for
Do not use this code for acute stroke, transient ischemic attack, or lower-limb weakness without a documented cerebrovascular cause. Check documentation if the affected side or dominant side is unclear.
Coding tip
Verify that the residual deficit is sequenced as a late effect and that the chart states right dominant side before assigning I69.941.
