Torus fx upper end of unsp tibia, subs for fx w nonunion

This code signifies a torus fracture, also known as a buckle fracture, affecting the upper portion of the tibia in an unspecified leg. A torus fracture is an incomplete fracture where one side of the bone buckles without a break in the cortex. The "subsequent encounter for fracture with nonunion" indicates that the patient is receiving ongoing care for this fracture, and it has failed to heal properly.

Use this code when documenting follow-up care for a patient with a previously diagnosed torus fracture of the proximal tibia that has not united. This includes situations where the patient is undergoing treatment for the nonunion, such as bone grafting, electrical stimulation, or revision surgery. It is also appropriate for monitoring the progress of a nonunion without active intervention.

• Ensure documentation clearly states "nonunion" for the torus fracture.
• Verify the encounter is for follow-up care, not the initial treatment.
• Laterality (left/right) is unspecified, so only use this code if the medical record does not specify the affected leg.
