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

This code indicates a fracture of the first thoracic vertebra (T1) where the specific type of fracture is not documented. Importantly, it signifies that the fracture has failed to heal properly after an initial treatment, and the patient is receiving ongoing care for this complication.

Use this code for follow-up encounters when a patient is being treated for a T1 vertebral fracture that has developed nonunion, and the initial fracture type was not specified. This applies to situations where the provider is managing the nonunion, such as considering or performing revision surgery, bone grafting, or prolonged immobilization.

• Ensure documentation clearly states "nonunion" and specifies the first thoracic vertebra.
• An appropriate seventh character (K) is crucial for subsequent encounters with nonunion.
• Do not use this code for initial encounters or for fractures that are healing normally.
