Disp fx of 3rd metatarsal bone, unsp ft, 7thP

This code describes a situation where a patient has a fracture of the third metatarsal bone in an unspecified foot that was previously treated but has healed improperly, resulting in a malunion. The fracture was also displaced, meaning the bone fragments were not in their normal alignment.

Use this code for follow-up encounters where a previously diagnosed and treated displaced third metatarsal fracture is now presenting with evidence of malunion. This applies when the patient is still receiving active treatment for the malunion, such as physical therapy, bracing, or surgical planning for corrective osteotomy.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed healing."
• Verify the fracture is of the third metatarsal and that the displacement was noted in the initial injury.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
