Late effect of injury to nerve root(s), spinal plexus(es), and other nerves of trunk

This code signifies a persistent neurological deficit or symptom resulting from a past injury to a nerve root, spinal plexus, or other nerves within the trunk. It describes the long-term consequences, such as chronic pain, weakness, or sensory loss, that manifest after the acute phase of the original nerve trauma has resolved.

Apply this code when documentation clearly indicates a current neurological condition directly attributable to a previous injury involving the nerve roots, spinal plexuses, or trunk nerves. This is appropriate for patients presenting with ongoing symptoms years or months after the initial trauma, and when the acute injury itself is no longer being treated.

• Always sequence this code after the code identifying the specific nature of the late effect (e.g., chronic pain, muscle weakness).
• Ensure documentation specifies the cause of the late effect as an injury to a nerve root, plexus, or trunk nerve, not just a general nerve injury.
• Distinguish from acute nerve injuries; this code is for residual conditions, not the initial injury or its immediate complications.
