Torus fx upper end of left tibia, subs for fx w malunion

This code describes a specific type of incomplete fracture, often seen in children, affecting the top portion of the left shin bone. In this particular instance, the fracture has previously been treated but has healed in an unsatisfactory position, resulting in a malunion.

Use this code for follow-up encounters where a patient is being managed for a torus fracture of the proximal left tibia that has healed incorrectly. This includes situations where the malunion is being monitored, or when further intervention (e.g., corrective osteotomy) is being planned or performed due to the malunion.

• Ensure documentation clearly specifies "torus fracture" and "malunion" for the left tibia.
• Verify the encounter is "subsequent" and not an initial treatment for the fracture.
• Confirm laterality (left) is explicitly stated in the medical record.
