Displ suprcndl fx w intrcndl extn low end unsp femr, 7thN

This code describes a displaced fracture of the lower end of the femur, specifically above the condyles, which also extends into the condyles themselves. It indicates a subsequent encounter for a severe open fracture (Type IIIA, IIIB, or IIIC) that has failed to heal properly (nonunion). The specific femur (left or right) is not identified.

Use this code when documenting follow-up care for a patient with a previously treated, severe open supracondylar-intracondylar femoral fracture that has not united. This applies to situations where the fracture site is still open or has been surgically opened for treatment, and the bone fragments have not fused. This code is appropriate for ongoing management of the nonunion, such as further surgical intervention or extended conservative treatment.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify that this is a subsequent encounter for the fracture, not the initial treatment.
• If the laterality of the femur is known, a more specific code should be used (e.g., S72.461N for right, S72.462N for left).
