Disp fx of 1st metatarsal bone, r ft, subs for fx w malunion

This code signifies a right foot injury involving a first metatarsal fracture that has healed improperly, resulting in a malunion. The fracture was initially displaced, meaning the bone fragments were not in their normal alignment.

Apply this code when documenting follow-up care for a patient whose previously displaced right first metatarsal fracture has united in an anatomically incorrect position. This would be used during encounters addressing the complications or ongoing management of this malunion, such as for pain, functional limitations, or consideration of corrective surgery.

• Ensure documentation explicitly states "malunion" and specifies the right first metatarsal.
• Confirm the initial fracture was displaced; if not, a different malunion code may be appropriate.
• This code is for subsequent encounters; the initial fracture treatment would have used an initial encounter code.
