Oth traum displ spondylolysis of fourth cervcal vert, init

This code signifies a traumatic forward slippage of the C4 vertebra over the C5 vertebra, where the vertebral body has shifted out of its normal alignment due to an injury. This specific code indicates that the fracture is closed (skin intact) and the patient is receiving initial treatment for this injury.

Use this code for patients presenting with a newly diagnosed, acute traumatic spondylolisthesis of the C4 vertebra that is documented as displaced. Documentation should clearly state the traumatic etiology, the specific cervical level (C4), the displaced nature of the spondylolisthesis, and that it is a closed fracture. This code is appropriate for the initial hospitalization or encounter for definitive treatment.

• Ensure documentation specifies "traumatic" and "displaced" for accurate code assignment.
• Verify the specific cervical vertebral level (C4) to differentiate from other cervical spondylolisthesis codes.
• The "A" seventh character indicates an initial encounter; use subsequent characters for follow-up care.
