0.000What This Code Means
Weakness or paralysis affecting only one limb, but neither the specific limb (arm or leg) nor the side (right or left) is specified.
Coding Tips
- •This is the least specific monoplegia code; always attempt to obtain more detailed information from the provider to assign a more specific code
- •Use this code only when documentation is insufficient to determine limb type and laterality
Clinical Significance
Monoplegia, unspecified affecting an unspecified side is the least specific monoplegia code, indicating that neither the limb type (arm vs. leg), the side (left vs. right), nor the dominance status is documented. This code should rarely be used as even basic clinical examination identifies which limb is paralyzed. It represents a significant documentation improvement opportunity and should prompt provider query for additional details.
Documentation Requirements
- ✓Documentation of monoplegia (paralysis of a single limb)
- ✓Clinical evidence supporting the diagnosis
- ✓Underlying etiology when known
- ✓Functional impact
- ✓Active management plan
