Nondisp Maisonneuve's fx r leg, subs for clos fx w nonunion

This code signifies a non-displaced Maisonneuve's fracture affecting the right leg, which is a specific type of ankle fracture involving a spiral fracture of the proximal fibula with an associated ankle injury. The "subsequent encounter" indicates that the patient is receiving routine follow-up care during the healing phase, and "nonunion" specifies that the fracture has failed to heal properly.

This code is appropriate for documentation of ongoing management of a patient with a right Maisonneuve's fracture where the bone fragments are still in their anatomical position, but the fracture has not united. This would be used during follow-up appointments, physical therapy, or other services related to the continued treatment of the nonunion.

• Confirm laterality (right leg) and the specific type of fracture (Maisonneuve's) are clearly documented.
• Ensure "nonunion" is explicitly stated by the provider, indicating a failure of the fracture to heal.
• Verify that the encounter is for follow-up care, not the initial treatment of the fracture.
