Incomplete atypical femoral fracture, right leg, init

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. It indicates that the fracture has not yet extended through the entire bone cortex. The "initial encounter" specifies that the patient is receiving active treatment for this newly diagnosed fracture.

Apply this code for a patient presenting with a newly identified, non-displaced or hairline stress fracture of the right femur, confirmed radiographically as an atypical femoral fracture. Documentation should clearly state the incomplete nature of the fracture, its location on the right leg, and that this is the first time the patient is being treated for this specific fracture. This code is often used in patients with a history of osteoporosis or prolonged bisphosphonate therapy.

• Ensure documentation explicitly states "incomplete" and "atypical femoral fracture" to differentiate from other femoral fractures.
• Verify the laterality (right leg) is clearly documented; incorrect laterality is a common coding error.
• Confirm "initial encounter" is appropriate; subsequent encounters for follow-up care or healing would require a different seventh character.
