Monoplegia of lower limb affecting right nondominant side

This code signifies paralysis affecting a single lower limb, specifically the right leg, when that side is not the patient's dominant side. This condition results in significant impairment of motor function and mobility in the affected extremity.

Apply this code when documentation clearly indicates monoplegia of the right lower limb and specifies that the right side is nondominant. This is typically seen in cases of stroke, spinal cord injury, or other neurological insults where only one lower extremity is paralyzed.

• Ensure documentation explicitly states "nondominant" for the right side; otherwise, an unspecified dominance code may be more appropriate.
• Distinguish from hemiplegia, which involves paralysis of one side of the body (e.g., right arm and right leg).
• Always code the underlying cause of the monoplegia first, followed by this code.
