Oth traum nondisp spondylolysis of 2nd cervcal vert, 7thB

This code signifies a fracture of the second cervical vertebra (C2) that has resulted in a traumatic spondylolisthesis, meaning a forward displacement of one vertebra over another, but without any significant displacement of the vertebral body itself. The fracture is open, indicating a break in the skin or mucous membrane that exposes the bone. This specific code is for the initial encounter for treatment of this injury.

Use this code for a patient presenting with an acute, traumatic, nondisplaced spondylolisthesis of the C2 vertebra where the fracture is open. Documentation should clearly state an open fracture of C2, traumatic etiology, and confirm that the spondylolisthesis is nondisplaced. This code is appropriate for the initial phase of care, including emergency department visits, initial hospital admissions, or the first surgical intervention.

• Ensure documentation specifies "nondisplaced" spondylolisthesis; otherwise, a displaced code may be more appropriate.
• Verify the encounter type is "initial" for this specific code; subsequent encounters will require a different seventh character.
• Distinguish between traumatic spondylolisthesis and degenerative spondylolisthesis, as they are coded differently.
