0.000What This Code Means
Weakness or paralysis affecting only the left leg in a person whose left side is not their dominant side.
Coding Tips
- •Ensure documentation clearly indicates the patient is right-dominant before assigning this left nondominant code
- •Link the monoplegia to its underlying cause (stroke, spinal cord injury, nerve damage) in the medical record when possible
Clinical Significance
Monoplegia of the lower limb affecting the left nondominant side is the most common laterality-specific lower limb monoplegia code, occurring in right-dominant individuals with left leg paralysis. This presentation is frequently seen as a sequela of stroke affecting the contralateral motor cortex. Despite being the nondominant side, left leg paralysis significantly impacts walking, balance, and fall risk.
Documentation Requirements
- ✓Documentation of monoplegia isolated to the left lower extremity
- ✓Right-side dominance documented (left is nondominant)
- ✓Underlying cause documented and coded
- ✓Neurological examination findings
- ✓Mobility and functional status
- ✓Fall risk assessment
- ✓Active treatment plan
