Unsp traum nondisp spondylolysis of 4th cervcal vert, 7thB

This code signifies a traumatic injury to the fourth cervical vertebra (C4) where the vertebral body has shifted forward relative to the vertebra below it (spondylolisthesis), but without a complete displacement. The fracture is open, meaning there is a break in the skin or mucous membrane leading to the fracture site, and this code is for the initial treatment of the injury.

Apply this code for a patient presenting with an open traumatic spondylolisthesis of the C4 vertebra, where the medical record explicitly states the displacement is "nondisplaced" or "unspecified" and this is the first time the patient is receiving active treatment for this specific injury. Documentation should clearly indicate the traumatic etiology, the specific cervical level (C4), the open nature of the fracture, and the initial encounter for care.

• Ensure documentation specifies "nondisplaced" or "unspecified" spondylolisthesis; otherwise, a code for displaced spondylolisthesis may be more appropriate.
• Verify the encounter type is "initial" for active treatment. Subsequent encounters for routine healing or complications will require different seventh characters.
• Always confirm the specific cervical vertebral level (C4 in this case) as codes are highly granular for spinal injuries.
