Displ Maisonneuve's fx r leg, 7thN

This code signifies a displaced Maisonneuve's fracture in the right leg that has failed to heal properly (nonunion). It specifically applies to open fractures classified as Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. The "subsequent encounter" designation means the patient is receiving follow-up care for the fracture after the initial treatment.

Use this code for patients presenting for ongoing management of a previously treated, but unhealed, displaced Maisonneuve's fracture of the right leg. This is appropriate when the initial injury was an open fracture of a severe type (IIIA, IIIB, or IIIC) and the fracture site shows evidence of nonunion. This code would be used for follow-up visits, cast changes, or further surgical planning related to the nonunion.

• Always confirm the laterality (right leg) and the specific type of open fracture (IIIA, IIIB, or IIIC) from the medical record.
• Ensure documentation clearly supports nonunion, not just delayed union, for accurate code assignment.
• Remember to also code any associated complications, such as infection, if present.
