Oth fracture of first thor vertebra, subs for fx w nonunion

This code signifies a fracture of the first thoracic vertebra (T1) that is not a compression fracture, and is currently in a state of nonunion. Nonunion indicates that the bone fragments have failed to heal together after a sufficient period of time, requiring ongoing medical management. This diagnosis is made during a follow-up encounter for the persistent fracture.

Use this code for patients presenting for follow-up care of a previously diagnosed T1 fracture (excluding compression fractures) where imaging or clinical assessment confirms nonunion. This would apply to scenarios such as a patient returning for evaluation of persistent pain, consideration of further surgical intervention, or ongoing conservative management due to the unhealed fracture.

• Ensure documentation clearly specifies "nonunion" and that the fracture is of the first thoracic vertebra.
• Verify that the encounter is subsequent to the initial treatment of the fracture.
• Confirm the fracture type is "other" and not a compression fracture, as specific codes exist for compression fractures.
