Weakness or paralysis affecting one leg, but the specific side (left or right) is not documented or specified in the medical record.
Coding Tips
Clinical Significance
Monoplegia of the lower limb affecting an unspecified side indicates paralysis of one leg without laterality documentation. This condition significantly impacts mobility, gait safety, and fall risk. While less functionally devastating than hemiplegia or paraplegia, single leg paralysis still requires assistive devices, physical therapy, and ongoing monitoring. The unspecified side designation represents a documentation improvement opportunity.
Documentation Requirements
- ✓Documentation of monoplegia affecting one lower extremity
- ✓Clinical evidence of paralysis or severe weakness isolated to one leg
- ✓Underlying etiology (stroke, spinal cord lesion, peripheral nerve injury)
- ✓Mobility status and assistive device needs
- ✓Fall risk assessment
- ✓Active treatment or rehabilitation plan
