Displ bicondylar fx unsp tibia, 7thR

This code signifies a complex fracture involving both condyles of the tibia, where the bone fragments are not properly aligned. It specifically indicates that the fracture was initially an open fracture (meaning the bone broke through the skin) of a severe type (IIIA, IIIB, or IIIC), and that the patient is now being treated for a malunion, which is a complication where the bone has healed in an incorrect position. This code is used for subsequent encounters, not the initial treatment.

Use this code when documenting follow-up care for a patient who previously sustained a severe open bicondylar tibia fracture and has developed a malunion. This would apply to scenarios such as surgical correction of the malunion, cast changes, or ongoing physical therapy for a poorly healed fracture. It is appropriate when the laterality (left or right) of the tibia is not specified in the medical record.

• Ensure documentation clearly states "malunion" and specifies a previous open fracture of type IIIA, IIIB, or IIIC.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Only use this code when the medical record does not specify which tibia (left or right) was affected.
