Displ intertroch fx unsp femur, subs for clos fx w nonunion

This code describes a situation where a patient has a fracture between the greater and lesser trochanters of the femur that is no longer in its normal anatomical position. The fracture was previously treated, but the bone fragments have failed to heal together after a reasonable period, indicating a nonunion. This specific code is for a subsequent encounter for ongoing management of this unhealed, closed fracture.

Use this code when a patient presents for follow-up care of a previously diagnosed and treated intertrochanteric femur fracture that has not united. This applies to situations where the fracture was initially closed (skin intact) and the current visit is for continued management of the nonunion, such as evaluation for revision surgery, bone grafting, or ongoing conservative treatment.

• Ensure documentation clearly states "nonunion" and specifies a "subsequent encounter" for a closed fracture.
• Verify the fracture location is specifically intertrochanteric and that it is displaced.
• Do not use for initial treatment of the fracture or for malunion (healed in an incorrect position).
