Oth fracture of T9-T10 vertebra, subs for fx w nonunion

This code signifies a fracture of the T9 or T10 thoracic vertebrae that is not a compression fracture, burst fracture, or other specified type, and is currently in a nonunion state. This means the bone fragments have failed to heal together after a previous fracture event.

Apply this code when documenting follow-up care for a patient whose T9 or T10 vertebral fracture has been previously treated but has not successfully united. This is appropriate for encounters where the nonunion is being managed, such as for further evaluation, planning for revision surgery, or ongoing conservative management of the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the T9 or T10 level.
• This code requires an associated external cause code to describe the mechanism of injury, if known and applicable to the current encounter.
• Distinguish from malunion, which implies healing in an unsatisfactory position, whereas nonunion implies a complete failure to heal.
