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

This code describes a specific type of incomplete fracture, a torus or buckle fracture, affecting the upper portion of the left fibula. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "malunion" signifies that the bone has healed in an unsatisfactory or deformed position.

This code is appropriate for documenting ongoing treatment, such as physical therapy, cast changes, or surgical planning, for a previously diagnosed torus fracture of the proximal left fibula that has healed incorrectly. It would be used when the malunion is the primary focus of the current encounter.

• Ensure documentation clearly specifies "torus fracture" and "malunion" for the left fibula.
• Verify the encounter type is "subsequent" and not initial or sequela.
• Confirm laterality (left) is accurately documented.
