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

This code signifies a long-term or residual effect from a past injury to any nerve in the wrist or hand, excluding the median, ulnar, or radial nerves. The specific nerve affected is not identified, and the laterality of the arm is also unspecified. This indicates a chronic condition resulting from a previous acute nerve trauma in this region.

Apply this code when documenting a patient presenting with persistent symptoms (e.g., chronic pain, weakness, numbness, or altered sensation) in the wrist or hand that are directly attributable to a prior nerve injury, and the specific nerve involved is not documented or is not one of the major nerves. This is appropriate for follow-up encounters where the initial acute injury has resolved but its neurological sequelae persist.

• Only use this code for sequelae (late effects) of a past injury, not for acute nerve injuries.
• Ensure documentation clearly links the current symptoms to a previous nerve injury in the wrist or hand.
• If the specific nerve (median, ulnar, radial) or laterality is known, a more specific code should be used.
