Injury of peripheral nerves of neck, initial encounter

This code signifies a traumatic injury to any of the peripheral nerves originating in the cervical region, such as the brachial plexus, phrenic nerve, or cervical spinal nerves. This injury can involve stretching, compression, contusion, or laceration of these nerves, leading to motor, sensory, or autonomic dysfunction in the head, neck, shoulder, or upper extremity.

Use this code for the initial encounter of a patient presenting with a newly diagnosed injury to a peripheral nerve of the neck, often following trauma like whiplash, falls, or direct impact. Documentation should clearly specify the neck as the anatomical site of the peripheral nerve injury and indicate the acute nature of the injury.

• Ensure documentation specifies "initial encounter" for the treatment of the acute injury.
• Distinguish from central nervous system injuries (e.g., spinal cord) and nerve root compression due to disc disorders.
• Code any associated open wound or fracture separately, following sequencing guidelines.
