Unsp trochan fx unsp femr, 7thN

This code signifies a patient presenting with an unhealed fracture of the trochanteric region of the femur, where the initial injury was an open fracture classified as type IIIA, IIIB, or IIIC. The specific side of the femur (left or right) is not documented. The current encounter is for ongoing management of this nonunion.

Use this code when documenting a subsequent encounter for a patient with a previously diagnosed open trochanteric fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC) that has failed to heal. This applies when the laterality of the femur is not specified in the medical record and the nonunion is the primary focus of the current visit.

• Ensure documentation clearly states "nonunion" and specifies the original fracture was an open type IIIA, IIIB, or IIIC.
• Verify that the encounter is subsequent to the initial treatment of the fracture.
• If laterality (left or right femur) is documented, a more specific code should be selected.
