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

This code describes a complex fracture involving the lower end of the right femur, specifically a supracondylar fracture that extends into the condyles, and is displaced. This particular code is used for a subsequent encounter when the initial open fracture was classified as Type IIIA, IIIB, or IIIC (indicating significant soft tissue damage), and the fracture has failed to heal properly, resulting in a nonunion.

Use this code for follow-up visits or admissions when a patient with a previously diagnosed and treated open supracondylar and intracondylar fracture of the right femur (Gustilo-Anderson Type IIIA, IIIB, or IIIC) is presenting with evidence of nonunion. This would typically involve imaging studies confirming the lack of healing and clinical signs consistent with a nonunion. It is appropriate when the patient is receiving ongoing care for this specific complication.

• Ensure documentation clearly specifies "nonunion" as the reason for the subsequent encounter.
• Verify the laterality (right femur) and the specific fracture type (supracondylar with intracondylar extension).
• Confirm the initial open fracture was classified as Type IIIA, IIIB, or IIIC to justify the "N" seventh character.
