Nondisp fx of 4th metatarsal bone, l ft, 7thK

This code indicates a fracture of the fourth metatarsal bone in the left foot that is not displaced, meaning the bone fragments are still in their normal alignment. The "subsequent encounter for fracture with nonunion" specifies that this visit is for ongoing treatment of a fracture that has failed to heal properly.

Apply this code when a patient presents for follow-up care of a previously diagnosed, nondisplaced left fourth metatarsal fracture that has not united. This would include scenarios where surgical intervention or other treatments are being considered or performed to address the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the fourth metatarsal of the left foot.
• Confirm the fracture was initially nondisplaced; if displacement occurred, a different code would be appropriate.
• This code is for subsequent encounters; an initial encounter for the same fracture would use a different seventh character.
