Incomplete atypical femoral fracture, right leg, 7thG

This code signifies an incomplete stress fracture of the right femur, specifically an atypical femoral fracture (AFF), which is a rare but serious complication often associated with long-term bisphosphonate use. The "subsequent encounter" indicates the patient is receiving active treatment for the fracture, and "delayed healing" specifies that the fracture is not progressing to union at the expected rate.

Apply this code when documentation confirms an incomplete atypical femoral fracture of the right leg that is not healing as anticipated. This typically occurs during follow-up visits where the physician assesses the fracture's progress and notes a delay in consolidation. Supporting documentation would include imaging reports (X-rays, MRI) showing an incomplete fracture line and clinical notes explicitly stating delayed healing.

• Ensure the documentation clearly specifies "incomplete" and "atypical femoral fracture" to differentiate from other femoral fractures.
• Verify the laterality (right leg) is explicitly stated; separate codes exist for the left leg and unspecified.
• Confirm the encounter type is "subsequent" and that "delayed healing" is documented, as this impacts the 7th character.
