Complete lesion at C3 level of cervical spinal cord, subs

This code signifies a complete transection or severe damage to the spinal cord at the C3 vertebral level, resulting in a total loss of motor and sensory function below that point. This injury typically leads to quadriplegia and significant respiratory compromise due to involvement of the phrenic nerve.

Apply this code for follow-up encounters after the initial treatment of a C3 complete spinal cord lesion. This includes visits for rehabilitation, management of complications, or ongoing care related to the chronic effects of the injury. Documentation should clearly state "complete lesion," "C3 level," and indicate that this is not the initial encounter for the injury.

• Ensure documentation specifies "complete lesion" versus "incomplete lesion" (S14.12-).
• Verify the encounter type is "subsequent" (D) and not "initial" (A) or "sequela" (S).
• Always code the underlying cause of the spinal cord injury (e.g., fracture, dislocation) first, if applicable and still being treated.
