Nondisp bicondylar fx r tibia, subs for clos fx w nonunion

This code signifies a fracture involving both condyles of the right tibia that is not displaced, meaning the bone fragments are still in their anatomical position. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone has failed to heal completely after the expected healing period.

Apply this code when documenting ongoing treatment for a right tibial bicondylar fracture that has been previously diagnosed and is now showing signs of nonunion. This would be appropriate for patients undergoing further interventions, such as bone grafting or revision surgery, due to the lack of healing. It is also used for follow-up appointments where the nonunion status is being monitored.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify the encounter type is "subsequent" and not initial or sequela.
• Confirm the fracture is specifically bicondylar and affects the right tibia.
