Coding Tips

- •Distinguish between monoplegia (single limb) and hemiplegia (entire side) when reviewing clinical documentation
Clinical Significance
Monoplegia of the lower limb affecting the left dominant side is an uncommon presentation occurring in left-dominant individuals. This code requires documentation of both left leg paralysis and left-side dominance, which for lower extremities may refer to the preferred kicking leg or weight-bearing limb. These patients need ongoing physical therapy and mobility assistance to maintain function and prevent falls.
Documentation Requirements
- ✓Documentation of monoplegia isolated to the left lower extremity
- ✓Left-side dominance confirmed in the medical record
- ✓Underlying etiology documented and coded
- ✓Neurological exam findings
- ✓Functional impact on mobility and balance
- ✓Active treatment plan
