Nondisp fx of 1st metatarsal bone, unsp ft, 7thK

This code signifies a fracture of the first metatarsal bone in an unspecified foot that was initially treated but has not healed properly, leading to a nonunion. The fracture itself is not displaced, meaning the bone fragments are still in their normal anatomical alignment. This code is used when the patient is receiving ongoing care for this unhealed fracture.

This code is appropriate for follow-up visits where a patient is being managed for a previously diagnosed, nondisplaced first metatarsal fracture that has failed to unite. This includes scenarios such as continued casting, bracing, physical therapy, or surgical planning for the nonunion. It indicates that the fracture is still present and not healing as expected.

• Ensure documentation clearly states "nonunion" and that the fracture is of the first metatarsal and nondisplaced.
• Verify that this is a subsequent encounter for the fracture, not the initial treatment.
• Confirm that the foot is unspecified; if left or right is documented, a more specific code should be used.
