Nondisp unsp fx right lesser toe(s), subs for fx w nonunion

This code signifies a fracture of one of the lesser toes on the right foot that is not displaced, meaning the bone fragments are still in their normal alignment. The "unspecified" nature indicates that the specific lesser toe (e.g., second, third, fourth, or fifth) is not documented. The "subsequent encounter for fracture with nonunion" specifies that the patient is receiving ongoing care for this fracture, and it has failed to heal properly.

This code is appropriate for follow-up visits where a patient is being treated for a right lesser toe fracture that has not united after a reasonable healing period. This includes scenarios such as cast changes, physical therapy, or surgical planning for a nonunion, provided the initial fracture was nondisplaced and the specific toe wasn't identified. It would be used when the physician explicitly documents a nonunion of the fracture.

• Ensure documentation clearly states "nonunion" for this subsequent encounter.
• Verify the fracture is of a "lesser toe" (not the great toe) and on the "right" foot.
• If the specific lesser toe is documented (e.g., right second toe), a more specific code should be used.
