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

This code signifies a fracture of the fourth thoracic vertebra that is not a compression fracture, burst fracture, or other specified type, and has failed to heal properly after an initial treatment. It indicates that the patient is presenting for ongoing management of this unhealed fracture.

Use this code when documenting a patient's visit for a previously diagnosed and treated fracture of the fourth thoracic vertebra that has been determined to be a nonunion. This applies to follow-up appointments, evaluations for further intervention, or ongoing care related to the persistent nonunion.

• Ensure documentation clearly states "nonunion" and specifies the fourth thoracic vertebra.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the fracture is not a compression or burst type, as those have specific codes.
