Oth fx shaft of r femr, 7thN

This code signifies a nonunion of an open fracture of the shaft of the right femur, specifically when the initial injury was a severe open fracture (Type IIIA, IIIB, or IIIC). Nonunion indicates that the bone has failed to heal completely after a significant period.

Use this code for patients presenting for follow-up care, such as cast changes, wound care, or surgical intervention, for a previously diagnosed open right femoral shaft fracture that has not united. This applies when the original fracture was classified as a severe open fracture.

• Ensure documentation clearly states "nonunion" and specifies the right femur shaft.
• Verify the original open fracture was classified as Type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter for this specific nonunion would use a different code.
