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

This code signifies a fracture of the fourth metatarsal bone in the right foot that is not displaced, meaning the bone fragments remain in their normal alignment. The "subsequent encounter for fracture with nonunion" indicates that the patient is receiving ongoing treatment for this fracture, and the bone has failed to heal properly after the expected healing time.

This code is appropriate for follow-up visits, cast changes, or surgical interventions related to a previously diagnosed nondisplaced right fourth metatarsal fracture that has not united. It should be used when the physician explicitly documents nonunion of the fracture.

• Ensure documentation clearly states "nonunion" and specifies the fourth metatarsal of the right foot.
• Verify the fracture is indeed nondisplaced; displaced fractures require a different code.
• This code is for subsequent encounters only; an initial encounter would use a different code.
