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

This code signifies a torus, or buckle, fracture located at the top portion of the fibula bone, where the bone has compressed rather than fully broken. It indicates that the patient is in a subsequent phase of care for this specific fracture, and the bone is healing in an undesirable or misaligned position (malunion).

Use this code for follow-up encounters where a previously diagnosed torus fracture of the proximal fibula is being managed, and imaging or clinical assessment confirms that the fracture has healed, but with an anatomical deformity or angulation. This applies when the malunion is the primary focus of the current encounter, such as for evaluation of function or planning for corrective procedures.

• Ensure documentation clearly states "torus fracture" and specifies the "upper end" or "proximal" fibula.
• Verify that the encounter is for follow-up care and not the initial treatment of the fracture.
• Confirm that the physician's notes explicitly mention "malunion" to justify this specific seventh character.
