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

This code signifies a fracture of the fifth or sixth thoracic vertebra (T5-T6) that is not a compression or burst fracture, and has failed to heal properly after an initial treatment. The "subsequent encounter" indicates the patient is receiving ongoing care for this unhealed fracture.

This code is appropriate for follow-up visits where a patient is being managed for a previously diagnosed T5 or T6 vertebral fracture that has not united. This includes situations where the patient is undergoing further evaluation, receiving non-surgical treatment for the nonunion, or being prepared for surgical intervention to address the nonunion.

• Always ensure documentation clearly states "nonunion" for the fracture.
• Verify the specific thoracic vertebral level (T5 or T6) and the type of fracture (other than compression or burst).
• Pair with an external cause code if the cause of the original fracture is still relevant and documented.
