Type III traum spondylolysis of 2nd cervcal vert, 7thG

This code signifies a fracture of the C2 vertebra, specifically a Type III traumatic spondylolisthesis (hangman's fracture), that is in the process of healing slower than expected. It indicates that the patient is receiving ongoing care for this specific fracture during a subsequent visit, and the healing process is complicated by delay.

Apply this code for follow-up encounters where a patient with a previously diagnosed Type III traumatic spondylolisthesis of C2 is being monitored for fracture healing, and the physician explicitly documents "delayed healing." This code is appropriate when the patient is still under active treatment for the fracture, but not for the initial injury or for routine follow-up without delayed healing.

• Ensure physician documentation clearly states "delayed healing" for the C2 fracture.
• Do not use this code for the initial encounter; a code from the S12.14XA series would be appropriate for the initial visit.
• Distinguish from nonunion (S12.14XK) or malunion (S12.14XP), which represent different healing complications.
