0.000What This Code Means
Weakness or paralysis affecting one limb on the right side of the body in a person whose right side is dominant (right-handed).
Coding Tips
- •Verify documentation specifies which limb is affected (arm vs. leg) as additional specificity may be required
- •Confirm the dominant side is documented; if unclear, query the provider before assigning this code
Clinical Significance
Monoplegia, unspecified affecting the right dominant side identifies paralysis of a single limb on the right side in a right-dominant person without specifying which limb. This partially specified code captures laterality and dominance but lacks limb-type specification. The dominant side involvement amplifies functional impact regardless of which limb is affected. Provider query regarding the affected limb (arm vs. leg) should be pursued.
Documentation Requirements
- ✓Documentation of monoplegia affecting the right side
- ✓Right-side dominance confirmed
- ✓Underlying etiology documented
