Nondisp transverse fx shaft of unsp tibia, 7thK

This code signifies a fracture of the main part of the tibia that runs across the bone, has not broken through the skin, and the bone fragments are still aligned. The key aspect is that the fracture has failed to heal properly in the expected timeframe, and the patient is presenting for follow-up care for this specific complication.

Apply this code when a patient with a previously diagnosed transverse tibial shaft fracture, which was initially treated non-surgically, presents with evidence of nonunion. This is appropriate for subsequent encounters where the nonunion is being managed, such as for monitoring, casting changes, or preparation for further intervention.

• Ensure documentation clearly states "nonunion" and specifies the transverse nature of the fracture.
• Verify the encounter is for follow-up care of the nonunion, not initial treatment or routine healing.
• Confirm the fracture is of the tibial shaft and not another part of the tibia.
