Nondisp fx of base of nk of l femr, 7thN

This code signifies a non-displaced fracture located at the base of the neck of the left femur. It specifically indicates a subsequent encounter for a previously open fracture (Type IIIA, IIIB, or IIIC) that has developed a nonunion. This means the bone fragments are not healing together as expected after the initial injury and treatment.

Apply this code when documenting ongoing care for a patient with a non-displaced left femoral neck fracture, specifically at the base. It is appropriate for follow-up visits where the initial injury was an open fracture and the current assessment confirms a nonunion, requiring further management or evaluation.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for this specific fracture.
• Verify the original fracture was indeed an open fracture (Type IIIA, IIIB, or IIIC) as this impacts code selection.
• Confirm the fracture is non-displaced and located at the base of the neck of the left femur.
