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

This diagnosis code signifies a long-term effect or complication resulting from a past injury to a peripheral nerve in the right wrist or hand, excluding the median, ulnar, or radial nerves. This could involve damage to smaller, named nerves or unnamed branches affecting sensation or motor function in the specified area. The "sequela" aspect indicates that the initial acute injury has resolved, but its lasting impact persists.

Apply this code when documenting chronic pain, numbness, weakness, or other persistent neurological deficits in the right wrist or hand that are directly attributable to a previous nerve injury not involving the main median, ulnar, or radial nerves. Examples include post-traumatic neuropathy, scar tissue impingement on a digital nerve, or chronic denervation atrophy following an old laceration. This code is appropriate when the original injury is no longer acute.

• Always ensure documentation clearly links the current neurological deficit to a past injury of an "other" nerve in the right wrist or hand.
• Verify that the specific nerve involved is not the median, ulnar, or radial nerve, as those have their own specific codes.
• The "S" at the end of the code indicates sequela; do not use this code for acute injuries.
