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

This code signifies a traumatic anterior or posterior displacement of the third cervical vertebra, where the specific type of displacement is not documented. The patient is in a subsequent phase of care for the fracture, and the healing process is progressing slower than expected.

Apply this code for follow-up encounters involving a patient with a previously diagnosed, traumatically induced spondylolisthesis of C3 that lacks specific documentation of the displacement type (e.g., anterolisthesis, retrolisthesis). Documentation should clearly indicate delayed healing of the associated fracture.

• Ensure documentation specifies "subsequent encounter" and "delayed healing" for the fracture.
• Do not use if the type of spondylolisthesis (e.g., anterolisthesis, retrolisthesis) is clearly documented; a more specific code would be appropriate.
• This code requires an external cause code to describe the circumstances of the injury.
