Torus fx lower end of r fibula, subs for fx w nonunion

This code signifies a buckle fracture, or torus fracture, affecting the lower portion of the right fibula. The "K" extension indicates that the patient is in a subsequent phase of care for this fracture, and unfortunately, the bone has failed to heal properly, resulting in a nonunion.

Apply this code when documenting ongoing treatment for a right distal fibular torus fracture that has not united. This would be appropriate for follow-up visits, cast changes, or surgical interventions aimed at addressing the nonunion after initial treatment.

• Ensure documentation clearly specifies "right fibula" and "lower end" or "distal."
• Verify that the encounter is for ongoing management of the fracture and that nonunion has been diagnosed.
• Distinguish from initial encounters (A/B/C) or encounters for routine healing (D/G/P).
