Oth traum nondisp spondylolysis of 4th cervcal vert, 7thG

This code describes a cervical spine injury involving a forward slip of the C4 vertebra that is not due to a fracture of the pars interarticularis and has not shifted out of alignment. It specifically indicates that the patient is in a later stage of care for this fracture, and the healing process is taking longer than expected.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed nondisplaced traumatic spondylolisthesis of the C4 vertebra, and the physician documents delayed healing of the associated fracture. This would include situations where imaging shows incomplete union or persistent symptoms beyond the typical healing timeframe.

• Ensure documentation specifies "nondisplaced" and "traumatic" spondylolisthesis of C4.
• Verify the encounter is for "subsequent care" and explicitly states "delayed healing" of the fracture.
• Distinguish from initial encounters or those for routine healing without complications.
