Incomplete atypical femoral fracture, unspecified leg, 7thG

This code signifies an incomplete atypical femoral fracture that has not yet fully healed, specifically when the patient is presenting for follow-up care related to this ongoing healing process. Atypical femoral fractures are stress fractures that occur in the subtrochanteric region or femoral shaft, often associated with long-term bisphosphonate use. "Incomplete" indicates the fracture does not extend through both cortices of the bone.

This code is appropriate for subsequent encounters where a patient with a previously diagnosed incomplete atypical femoral fracture of an unspecified leg is being monitored for delayed healing. Documentation should clearly state "atypical femoral fracture," "incomplete," and indicate that the encounter is for follow-up of a fracture with delayed union or nonunion.

• Ensure documentation specifies "incomplete" and "atypical" to differentiate from complete or typical femoral fractures.
• The "G" in the seventh character indicates subsequent encounter for fracture with delayed healing; use "P" for nonunion or "S" for sequela.
• Always code the underlying cause of the atypical femoral fracture, such as long-term bisphosphonate use (e.g., T38.81XA), if applicable and documented.
