0.000What This Code Means
Weakness or paralysis affecting only the left arm in a person whose left side is their dominant side.
Coding Tips
- •Confirm left dominance is documented in the patient's medical record before assigning this code
- •Note the severity and functional limitations of the monoplegia to support clinical decision-making
Clinical Significance
Monoplegia of the upper limb affecting the left dominant side is an uncommon presentation occurring in left-handed patients who lose function in their primary hand. Like right dominant monoplegia, this severely impacts fine motor tasks, writing, and self-care, but it is seen less frequently given that only approximately 10% of the population is left-handed. Documentation must explicitly confirm left-hand dominance.
Documentation Requirements
- ✓Documentation of monoplegia isolated to the left upper extremity
- ✓Left-hand dominance explicitly documented
- ✓Underlying cause documented and coded
- ✓Motor examination findings
- ✓Functional limitations from loss of dominant hand
- ✓Occupational therapy and rehabilitation plan
- ✓Active management status
