Unsp fracture of T11-T12 vertebra, subs for fx w nonunion

This code signifies a non-union of an unspecified fracture involving the T11 or T12 thoracic vertebrae. Non-union indicates that the fracture has failed to heal completely after a typical healing period, requiring further medical attention. The "unspecified" nature means the specific type of fracture (e.g., compression, burst) is not documented.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed fracture of the T11 or T12 vertebra that has not united. This includes situations where surgical intervention for non-union is being planned or performed, or when conservative management for the non-union is ongoing. It should be used when the initial fracture type was not specified in the documentation.

• Ensure documentation clearly states "nonunion" and specifies the T11-T12 vertebral level.
• Verify this is a subsequent encounter for the fracture, not the initial treatment.
• If the specific fracture type (e.g., compression, burst) is documented, a more specific code should be used.
