Unsp trochan fx r femr, 7thN

This code signifies a persistent failure of a severe open trochanteric fracture on the right femur to heal, specifically when the fracture was initially classified as an open fracture type IIIA, IIIB, or IIIC. "Nonunion" indicates that the bone fragments have not fused together after a reasonable healing period. This diagnosis is made during a follow-up visit after the initial treatment.

This code is appropriate for documenting a patient encounter where a previously treated, severe open trochanteric fracture of the right femur (initially classified as IIIA, IIIB, or IIIC) has failed to unite. This would be used during subsequent visits for ongoing management, evaluation of nonunion, or planning for further intervention.

• Ensure documentation clearly specifies the right femur and confirms the initial open fracture type (IIIA, IIIB, or IIIC).
• This code is for a "subsequent encounter," meaning it should not be used for the initial treatment of the fracture.
• Verify that the physician's notes explicitly state "nonunion" of the fracture.
