Oth fx low end l femr, 7thN

This code signifies a fracture in the lower part of the left thigh bone, specifically an "other" type of fracture, that has failed to heal properly (nonunion). It indicates that this is not the initial treatment encounter, and the original injury was a severe open fracture (Type IIIA, IIIB, or IIIC), meaning the bone broke through the skin.

Use this code for follow-up encounters where a patient is being treated for a nonunion of a previously sustained, severe open fracture of the distal left femur. This applies when the initial injury was classified as an open fracture type IIIA, IIIB, or IIIC, and the fracture has not united as expected.

• Ensure documentation clearly states "nonunion" and specifies the left femur's lower end.
• Verify the original fracture was an open fracture type IIIA, IIIB, or IIIC.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
