Unsp traum displ spondylolysis of sixth cervcal vert, 7thK

This code describes a nonunion of an unspecified traumatic spondylolisthesis of the C6 vertebra, indicating a forward slippage of the vertebral body that occurred due to trauma. The "unspecified" nature means the specific type of spondylolisthesis (e.g., isthmic, degenerative) is not documented. This code is used for encounters following the initial treatment of the fracture.

Use this code for a patient presenting for follow-up care of a C6 traumatic spondylolisthesis where the fracture has failed to heal (nonunion). Documentation should clearly state a traumatic etiology, involvement of the C6 vertebra, evidence of spondylolisthesis, and a confirmed nonunion status during a subsequent encounter.

• Ensure documentation specifies "traumatic" etiology; otherwise, a non-traumatic spondylolisthesis code may be more appropriate.
• Verify the encounter is for subsequent care of the nonunion, not the initial treatment of the fracture.
• Confirm the specific cervical vertebra (C6) is documented; codes exist for other cervical levels.
