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

This code signifies a fracture of an unspecified thoracic vertebra that has failed to heal properly, as documented during a follow-up visit. The exact location of the fracture within the thoracic spine is not specified in the medical record.

This code is appropriate for subsequent encounters when a patient is being treated for a previously diagnosed thoracic vertebral fracture that has developed a nonunion. This typically occurs when there is persistent pain, instability, or radiographic evidence of non-healing after an appropriate healing period.

• Ensure documentation clearly states "nonunion" of a thoracic vertebral fracture.
• Verify that the encounter is for follow-up care related to the fracture, not initial treatment.
• If the specific thoracic vertebra is documented (e.g., T1, T5), a more specific code should be used.
