Oth traum displ spondylolysis of 4th cervcal vert, 7thB

This code signifies a fracture of the fourth cervical vertebra (C4) that has resulted in a forward or backward displacement of the vertebral body relative to the one below it, caused by trauma. This specific injury involves an open fracture, meaning the skin and soft tissues overlying the fracture site are also compromised, exposing the bone. It indicates the patient is receiving initial treatment for this acute injury.

Use this code for patients presenting with a newly diagnosed traumatic spondylolisthesis of the C4 vertebra where the fracture is open. Documentation must clearly state the C4 level, the traumatic etiology, the presence of spondylolisthesis (displacement), and that it is an open fracture. This code is appropriate for the initial surgical repair or emergency room visit for this specific injury.

• Ensure documentation specifies "open fracture" and not just a closed fracture with displacement.
• Verify the vertebral level is C4; codes for other cervical vertebrae will differ.
• The "B" seventh character indicates an initial encounter for an open fracture; subsequent care will require different seventh characters.
