Displ subtrochnt fx unsp femr, 7thN

This code signifies a subtrochanteric fracture of the femur that is displaced and has failed to heal (nonunion). It specifically applies to open fractures classified as Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. The "subsequent encounter" aspect means this code is used for follow-up care after the initial treatment of the fracture.

Use this code when documenting ongoing management of a previously treated, displaced subtrochanteric femoral fracture that has developed nonunion. This includes scenarios where the patient is undergoing further surgical intervention, wound care, or rehabilitation for the nonunion of a severe open fracture. It is appropriate for any encounter after the initial treatment of the fracture.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture is subtrochanteric and displaced; do not use for other femoral fracture locations or types.
