Wedge comprsn fx fourth thor vert, subs for fx w nonunion

This diagnosis code indicates a specific type of spinal fracture affecting the fourth thoracic vertebra, where the vertebral body has collapsed in a wedge shape. The "nonunion" aspect signifies that the fracture has failed to heal completely after a previous treatment or period of healing. This is a subsequent encounter, meaning the patient is being seen for ongoing management of this unhealed fracture.

This code is appropriate for documenting follow-up visits for patients with a previously diagnosed wedge compression fracture of the T4 vertebra that has not united. This includes encounters for evaluation of nonunion, planning for further intervention (e.g., surgery, bone stimulation), or ongoing conservative management of the unhealed fracture. It should be used when the fracture is still considered active and not fully resolved.

• Always confirm the specific vertebral level (T4) and the type of fracture (wedge compression).
• Verify documentation clearly states "nonunion" and that this is a subsequent encounter for the fracture.
• Distinguish from malunion, which implies healing in an unsatisfactory position, versus nonunion, which implies a failure to heal.
