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

This code signifies a fracture of the first metatarsal bone in the left foot that was initially nondisplaced but has failed to heal properly, resulting in a nonunion. The patient is currently undergoing active treatment for this persistent nonunion.

This code is appropriate for follow-up encounters where a patient is receiving ongoing care for a previously diagnosed, nondisplaced fracture of the left first metatarsal that has progressed to a nonunion. This includes scenarios such as surgical intervention for nonunion, casting or bracing for nonunion management, or evaluation of nonunion healing progress.

• Ensure documentation clearly states "nonunion" and specifies the left first metatarsal.
• Verify the fracture was initially nondisplaced to accurately apply this code.
• This code indicates a subsequent encounter, so it should not be used for the initial fracture diagnosis.
