Oth traum nondisp spondylolysis of 3rd cervcal vert, 7thK

This code signifies a non-displaced traumatic spondylolisthesis affecting the third cervical vertebra, where the vertebral body has slipped forward but remains aligned. The "subsequent encounter for fracture with nonunion" indicates that the patient is receiving ongoing treatment for a fracture that has failed to heal properly. This condition can lead to chronic neck pain, neurological deficits, and instability.

Apply this code for patients presenting for follow-up care of a C3 traumatic spondylolisthesis that was initially non-displaced, and where imaging or clinical assessment confirms a nonunion of the associated fracture. Documentation should clearly state the cervical level (C3), the traumatic origin, the non-displaced nature of the spondylolisthesis, and the ongoing management of a nonunion.

• Ensure documentation specifies "nondisplaced" and "traumatic" to differentiate from other types of spondylolisthesis.
• The "K" seventh character is crucial, indicating a subsequent encounter for a fracture with nonunion. Do not use for initial treatment or routine healing.
• Always code the underlying cause of the trauma if known and still relevant to the current encounter.
