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

This diagnosis code signifies a traumatic anterior or posterior displacement of the C2 vertebral body relative to C3, specifically when the fracture is open (compound). This displacement, known as spondylolisthesis, is caused by an injury and involves the second cervical vertebra.

This code is appropriate for initial encounters where documentation confirms a traumatic spondylolisthesis of the C2 vertebra with an associated open fracture. Look for explicit statements of "open fracture" or descriptions indicating the bone has broken through the skin. This code is used for the initial treatment phase of the injury.

• Ensure documentation clearly specifies "open fracture" to differentiate from closed fractures.
• Verify the specific cervical vertebra involved is C2; other cervical levels have different codes.
• This "initial encounter" code is only used for the period when the patient is receiving active treatment for the injury.
