Oth fx low end l femr, 7thR

This code describes a situation where a patient has previously sustained an open fracture of the lower end of their left femur, specifically a severe type IIIA, IIIB, or IIIC open fracture, and is now presenting for follow-up care related to a malunion of that fracture. Malunion indicates that the fracture has healed, but in an unsatisfactory position or alignment.

Use this code for subsequent encounters when a patient with a documented history of a severe open distal left femoral fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC) is being treated for complications arising from the fracture healing improperly. This includes appointments for evaluation, management, or surgical correction of the malunion.

• Ensure documentation clearly specifies "subsequent encounter" and "malunion" for an open fracture.
• Verify the original fracture was of the distal left femur and classified as Gustilo-Anderson type IIIA, IIIB, or IIIC.
• Do not use for initial fracture treatment or for nonunion, which has a separate code.
