Injury of radial nerve at wrs/hnd lv of left arm, sequela

This code signifies a long-term or late effect resulting from an injury to the radial nerve specifically located at the wrist or hand level of the left arm. This could include persistent pain, weakness, sensory deficits, or functional limitations that arose as a direct consequence of a previous acute radial nerve injury in this anatomical region.

This code is appropriate for documenting conditions that are residual effects of a past radial nerve injury affecting the left wrist or hand, after the acute phase of the original injury has passed. It should be used when the patient is presenting for treatment or evaluation of these ongoing complications, rather than the initial acute injury itself.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., pain, muscle weakness).
• Ensure documentation clearly states the injury is to the radial nerve and specifies the left wrist/hand level.
• The "S" at the end indicates "sequela," meaning it's for late effects, not acute injuries.
