Stable burst fx T9-T10 vertebra, subs for fx w nonunion

This code signifies a stable burst fracture affecting the T9-T10 vertebrae that has progressed to a nonunion. It indicates that the fracture, while stable, has failed to heal properly, and this encounter is for follow-up care related to this ongoing issue.

Apply this code for patients presenting for evaluation or management of a previously diagnosed stable burst fracture of T9-T10 that has not united. This is appropriate for subsequent visits after the initial treatment phase, where nonunion is the primary concern.

• Ensure documentation clearly states "nonunion" and specifies the T9-T10 vertebral level.
• Verify the encounter is for follow-up care of the fracture, not the initial treatment.
• Confirm the "stable burst fracture" diagnosis is explicitly documented.
