Oth traum displ spondylolysis of 4th cervcal vert, 7thD

This code signifies a forward displacement of the fourth cervical vertebra (C4) over the fifth cervical vertebra (C5) due to a traumatic injury, where the displaced bone fragments are not in their anatomical position. This specific code is used when the patient is receiving follow-up care for this fracture, and the healing process is progressing as expected without complications.

Use this code for patients presenting for routine follow-up appointments after an initial traumatic displaced spondylolisthesis of C4. Documentation should clearly indicate a C4 spondylolisthesis, state it is displaced and traumatic in origin, and confirm that the encounter is for subsequent care with routine healing. This code is appropriate when the fracture is not yet fully healed but is progressing normally.

• Ensure documentation specifies "displaced" and "traumatic" to differentiate from non-displaced or congenital spondylolisthesis.
• Verify the encounter is for "subsequent care" and "routine healing"; do not use for initial treatment or encounters with delayed/nonunion.
• Always sequence this code after any acute injury codes if the patient is still being treated for other related acute conditions.
