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

This code signifies a traumatic injury to the seventh cervical vertebra (C7) where there is an anterior displacement (spondylolisthesis) of the vertebral body, but the displacement is not specified as to its grade or direction beyond anterior. The fracture is open, meaning there is a break in the skin or mucous membrane communicating with the fracture site, and this code is for the initial treatment encounter.

Use this code for a patient presenting with an acute, open fracture of the C7 vertebra resulting in an unspecified grade of nondisplaced traumatic spondylolisthesis. Documentation must clearly state an open fracture of C7 with traumatic spondylolisthesis, and specify that it is the initial encounter for treatment. This code is appropriate when the specific grade of spondylolisthesis (e.g., Grade I, II) is not documented.

• Ensure documentation explicitly states "open fracture" and "traumatic spondylolisthesis" of C7.
• The "B" seventh character indicates an initial encounter for an open fracture; subsequent encounters will require different seventh characters.
• Do not use this code if the spondylolisthesis is congenital, degenerative, or iatrogenic; it must be traumatic.
