Unsp fx right femur, subs for opn fx type I/2 w nonunion

This code signifies an ongoing treatment for an unspecified fracture of the right femur that was initially an open fracture (Type I or II), and has since failed to heal properly, resulting in a nonunion. The "unspecified" nature indicates that the specific location or type of fracture within the femur is not documented.

Apply this code when a patient presents for follow-up care, surgical intervention, or management of complications related to a previously sustained open right femoral fracture (Type I or II) that has not united. This is used when the documentation clearly states nonunion and the initial fracture was open, but the specific site of the fracture on the femur is not detailed.

• Ensure documentation explicitly states "nonunion" and that the initial fracture was "open type I or II."
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Do not use if the specific location of the femoral fracture (e.g., shaft, neck, condyle) is known; instead, use a more specific code.
