Unsp fracture of T5-T6 vertebra, subs for fx w nonunion

This code signifies an unstated type of fracture affecting the T5 or T6 thoracic vertebrae that has not healed properly, despite previous treatment. The patient is currently receiving care for this ongoing complication of the initial injury.

Apply this code when a patient presents for follow-up care, such as imaging, medication management, or surgical planning, for a previously diagnosed T5 or T6 vertebral fracture that has failed to unite. This is appropriate when the specific fracture type (e.g., compression, burst) was not documented or is unknown.

• Ensure documentation clearly states "nonunion" and specifies the T5 or T6 level.
• This code requires an external cause code to describe the circumstances of the injury.
• Do not use for initial encounters or for fractures that are healing normally.
