Monoplegia of upper limb affecting left dominant side

This code signifies paralysis affecting a single upper limb, specifically the left arm, in a patient whose left side is documented as their dominant side. This condition results in significant impairment of motor function and control in the affected arm.

Apply this code when medical record documentation clearly indicates monoplegia of the left upper extremity and explicitly states that the patient is left-hand dominant. This typically arises from neurological damage, such as stroke, spinal cord injury, or other central nervous system lesions.

• Ensure documentation specifies "left dominant side" in addition to left upper limb monoplegia.
• Do not use this code if the patient is right-hand dominant, even if the left arm is affected.
• Consider sequencing this code after the underlying cause of the monoplegia (e.g., stroke, spinal cord injury).
