Stable burst fx second lum vertebra, subs for fx w nonunion

This code signifies a stable burst fracture affecting the second lumbar vertebra, where the fracture has not healed properly (nonunion). The patient is presenting for follow-up care related to this unhealed fracture, not for initial treatment. A burst fracture involves the vertebral body being crushed in multiple directions.

Use this code for patients who have previously been diagnosed and treated for a stable burst fracture of the L2 vertebra, and are now returning for ongoing management of a confirmed nonunion. This applies to situations where the fracture fragments have not fused and the patient is experiencing persistent symptoms or requires continued monitoring.

• Ensure documentation clearly states "nonunion" and specifies the L2 vertebra.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture is described as "stable" in the clinical notes.
