Complete oblique atypical femoral fracture, left leg, 7thK

This diagnosis code signifies a complete fracture of the left femur that presents with an atypical oblique pattern, indicating a non-healing state (nonunion). This specific fracture type is often associated with long-term bisphosphonate use. The "K" suffix denotes a subsequent encounter for the ongoing management of this nonunion.

This code is appropriate for encounters where a patient is receiving active treatment for a previously diagnosed complete oblique atypical femoral fracture of the left leg that has failed to heal. Documentation should clearly state "nonunion" and specify the left femur as the affected site. This code is used after the initial treatment of the fracture.

• Ensure documentation explicitly states "atypical" and "oblique" fracture patterns, along with "nonunion."
• Verify laterality (left leg) is clearly documented.
• Do not use for initial fracture treatment or for routine follow-up of a healed fracture.
