Wedge comprsn fx first thor vertebra, subs for fx w nonunion

This code signifies a specific type of spinal fracture affecting the first thoracic vertebra, where the bone has compressed into a wedge shape. Crucially, it indicates that the fracture has not healed properly (nonunion) and the patient is presenting for follow-up care related to this ongoing issue.

Apply this code when documenting subsequent encounters for a patient diagnosed with a wedge compression fracture of the T1 vertebra that has failed to unite. This would include visits for ongoing management of the nonunion, such as evaluation for surgical intervention, pain management, or monitoring of healing progress.

• Ensure documentation clearly states "nonunion" to support the K seventh character.
• Verify the fracture location is specifically the first thoracic vertebra (T1).
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
