Injury of nerves at wrs/hnd lv of left arm, sequela

This code signifies a long-term or late-effect condition resulting from a previous injury to a peripheral nerve in the left wrist or hand, excluding the median, ulnar, and radial nerves. This sequela could manifest as chronic pain, weakness, sensory deficits, or functional impairment directly attributable to the original nerve damage.

Apply this code when documenting a current condition that is a residual effect of an old injury to a "other" specified nerve (e.g., digital nerve, interosseous nerve) in the left wrist or hand. This is appropriate for follow-up encounters where the acute injury has resolved, but its lasting impact on the nerve is still being managed.

• Always use a "S" (sequela) seventh character for conditions that are late effects of an injury.
• Ensure documentation clearly links the current nerve sequela to a past injury of an "other" nerve in the specified anatomical area.
• Do not use this code for acute injuries or for sequelae of median, ulnar, or radial nerve injuries, as those have more specific codes.
