Unsp fx second thor vertebra, subs for fx w nonunion

This code signifies an unconfirmed fracture of the second thoracic vertebra that has failed to heal properly after an initial treatment attempt. The patient is presenting for ongoing management of this persistent fracture.

Apply this code when documentation indicates a patient is being seen for follow-up care of a previously diagnosed, but unspecified, fracture of the T2 vertebra where nonunion has been confirmed. This would include scenarios such as continued pain, instability, or imaging showing lack of bony bridging at the fracture site.

• Ensure the documentation clearly states "nonunion" and specifies the second thoracic vertebra.
• Verify that this is a subsequent encounter for the fracture, not the initial treatment.
• Do not use if the specific type of fracture (e.g., compression, burst) is known; a more specific code should be chosen.
