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

This code signifies a torus (buckle) fracture affecting the upper portion of the left tibia. The "subsequent encounter" indicates that the patient is receiving follow-up care for this specific injury, and "nonunion" specifies that the fracture has failed to heal properly within the expected timeframe.

This code is appropriate for documenting ongoing treatment for a left proximal tibial torus fracture where the bone fragments have not united. It would be used for office visits, physical therapy sessions, or other encounters related to managing the nonunion, such as discussions about surgical intervention or continued conservative management.

• Ensure documentation clearly specifies "torus" or "buckle" fracture and the left tibia.
• Verify that the encounter is for follow-up care and that nonunion is explicitly stated or clearly implied in the medical record.
• Pair with appropriate external cause codes (V, W, X, Y) if the initial injury encounter is also being coded and the cause is known.
