Oth traum displ spondylolysis of 3rd cervcal vert, 7thG

This code signifies a forward slippage of the third cervical vertebra (C3) over the fourth (C4) due to a previous traumatic injury, where the vertebral body is no longer properly aligned and has shifted. The patient is in a subsequent phase of care, and the fracture associated with this spondylolisthesis is exhibiting delayed healing.

Apply this code for patients presenting for follow-up care of a previously diagnosed traumatic C3 spondylolisthesis with displacement, where imaging or clinical assessment confirms the fracture is not healing at the expected rate. Documentation should clearly indicate the traumatic origin, the specific cervical vertebra involved (C3), the displacement, and the delayed healing status.

• Ensure documentation specifies "traumatic" origin and "displaced" to differentiate from congenital or degenerative spondylolisthesis.
• The 7th character "G" is crucial, indicating a subsequent encounter for a fracture with delayed healing; do not use for initial care or routine healing.
• Always code the underlying fracture (e.g., S12.2XXA for initial encounter) if still active, in addition to the spondylolisthesis.
