Unsp traum nondisp spondylolysis of sixth cervcal vert, 7thK

This code describes a spinal injury involving the sixth cervical vertebra (C6) where one vertebral body has slipped forward on the one below it due to trauma, but the slippage is not specified as to type (e.g., isthmic, degenerative) and is not displaced. The fracture associated with this spondylolisthesis is currently in a nonunion state, and the patient is being seen for follow-up care related to this ongoing issue.

Use this code for a patient presenting for continued treatment or evaluation of a previously diagnosed traumatic, nondisplaced spondylolisthesis of C6 that has failed to heal. Documentation should clearly state "nonunion" of the fracture and indicate a "subsequent encounter" for the injury. This code is appropriate when the specific type of spondylolisthesis (e.g., isthmic, degenerative) is not documented.

• Ensure documentation specifies "nonunion" and "subsequent encounter" for accurate code assignment.
• Verify the cervical vertebra level (C6) and that the spondylolisthesis is nondisplaced and traumatic in origin.
• Distinguish from initial encounters (A), subsequent encounters for routine healing (D-J), and sequela (S) codes.
