Injury of median nerve at wrs/hnd lv of right arm, sequela

This code signifies a lasting effect or complication resulting from a past injury to the median nerve in the right wrist or hand. This could manifest as chronic pain, persistent numbness, weakness, or impaired motor function in the distribution of the median nerve, such as the thumb, index, middle, and part of the ring finger.

Apply this code when documenting a patient presenting with ongoing symptoms directly attributable to a previous injury of the median nerve in the right wrist or hand, after the initial acute phase of the injury has passed. This is appropriate for conditions like chronic carpal tunnel syndrome stemming from trauma, or persistent nerve damage following a laceration or fracture.

• Ensure documentation clearly links the current symptoms to a past median nerve injury in the specified location.
• Verify the "S" seventh character for sequela, indicating the long-term effects of a previous injury.
• Do not use this code for acute injuries; instead, use the appropriate acute injury code.
