Stable burst fx unsp thor vertebra, subs for fx w nonunion

This code describes a burst fracture of an unidentifiable thoracic vertebra that is considered stable, meaning it does not pose an immediate risk of spinal cord injury. The "nonunion" aspect indicates that the fractured bone fragments have failed to heal together after a previous treatment attempt.

This code is appropriate for follow-up encounters where a patient is being managed for a previously diagnosed stable burst fracture of an unspecified thoracic vertebra, and the fracture has not united. This includes situations where further treatment for the nonunion is being planned or ongoing, such as revision surgery or continued conservative management.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify the encounter is for follow-up care of the fracture, not the initial treatment.
• Confirm the specific thoracic vertebra is not documented; otherwise, a more specific code should be used.
