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

This code signifies a fracture of one or more lesser toes on the left foot that is not displaced, meaning the bone fragments remain in their normal alignment. The "subsequent encounter for fracture with nonunion" indicates that the fracture has failed to heal properly after an initial treatment period, and the patient is receiving ongoing care for this complication.

Apply this code when a patient presents for follow-up care of a previously diagnosed, nondisplaced fracture of the left lesser toe(s) that has not united. This includes situations where surgical intervention or other treatments are being considered or performed to address the nonunion. It is appropriate for office visits, hospital encounters, or other healthcare settings where the nonunion is the focus of the encounter.

• Always confirm the laterality (left) and the specific toe(s) involved from the medical record.
• Ensure documentation clearly states "nonunion" and that this is a subsequent encounter, not the initial treatment.
• Pair this code with external cause codes (e.g., W00-Y38) if the cause of the fracture is known and relevant to the encounter.
