Complete transverse atyp femoral fracture, right leg, 7thG

This code describes a severe, complete break across the shaft of the right femur, occurring in an atypical location, often associated with long-term bisphosphonate use. The "atypical" nature refers to specific radiographic features distinguishing it from typical osteoporotic fractures. The "subsequent encounter for fracture with delayed healing" indicates that the patient is receiving active treatment for the fracture, but the healing process is taking longer than expected.

Use this code for a patient presenting for follow-up care of a previously diagnosed complete atypical transverse femoral fracture of the right leg, where the fracture has not healed within the anticipated timeframe. Documentation should clearly state "delayed healing" and specify the right leg and the atypical nature of the fracture. This code is appropriate for encounters involving ongoing management, such as repeat imaging, cast changes, or surgical revisions due to non-union or delayed union.

• Ensure documentation explicitly states "delayed healing" and specifies "complete transverse atypical femoral fracture."
• Do not confuse with nonunion (M84.454G) or malunion (M84.354G); delayed healing implies the fracture is still in the process of healing, albeit slowly.
• Always sequence this code after any associated external cause codes (e.g., W19.XXXA for fall, if applicable) and before any procedure codes for treatment.
