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

This code signifies a wedge-shaped compression fracture of an unidentifiable thoracic vertebra that has failed to heal properly. The "nonunion" aspect indicates that the bone fragments have not fused together after a typical healing period, leading to persistent instability and symptoms. This diagnosis is used when the patient is receiving active treatment for the nonunion.

This code is appropriate for patients presenting for follow-up care, surgical intervention, or other treatments specifically addressing the nonunion of a previously diagnosed thoracic wedge compression fracture. It should be used when the specific thoracic vertebral level (T1-T12) is not documented. This code is not for initial fracture treatment.

• Ensure documentation clearly states "nonunion" and that the encounter is for ongoing treatment of this complication.
• Verify that the fracture is described as a "wedge compression" type and located in the thoracic spine.
• If the specific thoracic vertebral level is documented (e.g., T4, T7), a more specific code from the S22.01-S22.08 series should be used.
