BillableMonoplegia of upper limb affecting left nondominant side
HCC Category Mapping
What This Code Means
Weakness or paralysis affecting only the left arm in a person whose left side is not their dominant side.
Coding Tips
- •Verify right dominance is documented to support the assignment of this left nondominant code
- •Review the underlying etiology (stroke, trauma, nerve compression) to ensure accurate clinical documentation
Clinical Significance
Monoplegia of the upper limb affecting the left nondominant side is the most common upper limb monoplegia presentation in the general population, as most people are right-handed. Left arm paralysis in a right-handed person preserves dominant hand function but still creates significant limitations in bilateral tasks, balance (loss of arm swing in gait), and activities requiring two hands. Ongoing occupational therapy helps develop one-handed strategies.
Documentation Requirements
- ✓Documentation of monoplegia isolated to the left upper extremity
- ✓Right-hand dominance documented (left is nondominant)
- ✓Underlying cause documented and coded
- ✓Motor strength examination findings
- ✓Functional limitations documented
- ✓Active rehabilitation and management plan
