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

This code signifies a burst fracture of the fourth thoracic vertebra that is considered stable, meaning it does not pose an immediate threat to spinal cord integrity. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone fragments have failed to heal together after a typical healing period.

Use this code for patients presenting for ongoing management of a previously diagnosed stable burst fracture of the T4 vertebra where imaging or clinical assessment confirms that the fracture has not united. This would include clinic visits for pain management, physical therapy, or surgical planning related to the nonunion. It is appropriate when the patient is no longer in the initial acute phase of treatment.

• Ensure documentation clearly states "stable burst fracture" and specifies the T4 level.
• Verify that the encounter is for follow-up care and that nonunion is explicitly documented.
• Do not use for initial treatment or for fractures that have healed.
