Unsp traum displ spondylolysis of 2nd cervcal vert, 7thD

This code signifies a follow-up encounter for a patient with a traumatic displacement of the second cervical vertebra (C2) where the fracture is healing routinely. Spondylolisthesis refers to the forward slippage of one vertebra over another, in this case, specifically C2, resulting from an injury.

Use this code for subsequent visits where a patient is receiving ongoing care for a C2 traumatic spondylolisthesis that is progressing as expected towards healing. Documentation should clearly indicate a previous traumatic injury to C2, a diagnosis of spondylolisthesis, and a current assessment of routine fracture healing.

• Ensure documentation specifies "subsequent encounter" and "routine healing" to differentiate from initial or delayed healing encounters.
• Verify the specific cervical vertebra involved; this code is exclusively for C2.
• Do not use if the spondylolisthesis is congenital, degenerative, or pathological; this code is for traumatic origin only.
