Displ spiral fx shaft of l femr, subs for clos fx w nonunion

This code indicates a spiral fracture located in the shaft of the left femur that has become displaced. The fracture has failed to heal properly (nonunion) and the patient is presenting for follow-up care or treatment of this ongoing issue.

Use this code when documenting a patient encounter for a previously diagnosed displaced spiral fracture of the left femoral shaft that has not united. This applies to subsequent visits for management, evaluation, or treatment of the nonunion, such as before a revision surgery or during ongoing conservative management.

• Ensure documentation clearly states "nonunion" and specifies the left femur and spiral fracture type.
• Verify the encounter is for a subsequent visit related to the nonunion, not the initial treatment.
• Pair with external cause codes (V, W, X, Y) if the cause of the fracture is known and relevant to the encounter.
