This code signifies a persistent failure of bone healing (nonunion) in an open fracture of the femoral neck, where the initial injury involved significant soft tissue damage (Type IIIA, IIIB, or IIIC). This is a subsequent encounter, indicating the patient is receiving ongoing care for this complex fracture complication.

Apply this code when documenting follow-up care for a patient with a previously diagnosed open femoral neck fracture that has failed to unite. This includes scenarios such as continued monitoring, surgical intervention for nonunion, or management of associated complications.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Always code the specific type of nonunion if further detail is available (e.g., atrophic, hypertrophic).
