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

This code indicates an unspecified fracture of the T9 or T10 thoracic vertebra that has not healed properly, meaning there is a failure of bone union. This diagnosis is made during a follow-up visit after the initial treatment for the fracture has begun. The specific type of fracture (e.g., compression, burst) is not documented.

Use this code for subsequent encounters when a patient presents with a previously diagnosed T9 or T10 vertebral fracture that is now complicated by nonunion. This applies when the physician is managing the nonunion, such as evaluating for further treatment options or monitoring the healing process. It is appropriate when the exact nature of the original fracture is not specified in the medical record.

• Requires an additional code for any associated complications or external causes, if applicable.
• Do not use for initial encounters or for fractures that are healing normally.
• Ensure documentation clearly states "nonunion" and specifies the T9-T10 level.
