Type III traum spondylolysis of 4th cervcal vert, 7thB

This code signifies a traumatic forward displacement of the fourth cervical vertebra (C4) on the fifth cervical vertebra (C5) due to a fracture, specifically a Type III spondylolisthesis. This type involves a bilateral fracture of the C4 pedicles or articular processes, resulting in instability. The "initial encounter" indicates the patient is receiving active treatment for the acute injury.

This code is appropriate for patients presenting with a newly diagnosed traumatic spondylolisthesis of C4, characterized by a bilateral fracture of the posterior elements, and who are undergoing initial surgical or non-surgical management. Documentation should clearly state a traumatic etiology, the specific cervical level (C4), the Type III classification, and an open fracture.

• Ensure documentation specifies "open fracture" to justify the 6th character 'B'.
• Confirm the cervical level is C4; similar injuries at other levels have different codes.
• Distinguish between traumatic spondylolisthesis and degenerative spondylolisthesis, which are coded differently.
