Complete lesion at C4 level of cervical spinal cord, subs

This code signifies a complete transection or severe damage to the cervical spinal cord at the C4 vertebral level, resulting in a total loss of motor and sensory function below that point. It specifically indicates that the patient is receiving follow-up care for this previously diagnosed injury, rather than initial treatment.

Use this code for patients presenting for ongoing management, rehabilitation, or evaluation of complications related to a complete C4 spinal cord injury after the initial acute phase of treatment. Documentation should clearly state "complete lesion," "C4 level," and indicate a "subsequent encounter" or follow-up visit.

• Ensure documentation specifies "complete" lesion; partial lesions at C4 are coded differently.
• Verify the encounter type; "D" for subsequent encounter is crucial and distinguishes it from initial or sequela encounters.
• Always code any associated neurological deficits (e.g., quadriplegia) separately, as this code only describes the injury itself.
