Unsp traum nondisp spondylolysis of 4th cervcal vert, init

This code describes a fracture of the fourth cervical vertebra (C4) where the vertebral body has slipped forward relative to the vertebra below it, but the displacement is not specified as a particular type (e.g., retrolisthesis). The fracture is traumatic in origin, and the initial treatment for this closed injury is being provided.

This code is appropriate for the initial encounter when a patient presents with a newly diagnosed, traumatic, nondisplaced spondylolisthesis of the C4 vertebra. Documentation should clearly indicate the cervical level, the traumatic etiology, the absence of specific displacement details, and that the fracture is closed.

• Ensure documentation specifies "nondisplaced" or lacks mention of displacement for accurate code assignment.
• Verify the encounter is the "initial encounter" for treatment of the fracture; subsequent care would use a different seventh character.
• Confirm the injury is traumatic; non-traumatic spondylolisthesis (e.g., degenerative) would be coded differently.
