Displaced intertroch fx l femur, subs for clos fx w nonunion

This code describes a left femur fracture located between the greater and lesser trochanters, which has shifted from its normal alignment. The fracture has failed to heal properly after an initial treatment, and the patient is now receiving follow-up care for this ongoing issue.

Use this code when documenting subsequent encounters for a patient with a previously diagnosed and treated displaced intertrochanteric fracture of the left femur that has not united. This applies to situations where the fracture was initially managed non-surgically (closed treatment) and is now presenting as a nonunion.

• Ensure documentation clearly states "nonunion" and specifies the left femur.
• Verify the fracture was initially treated as a "closed fracture."
• Confirm this is a subsequent encounter, not the initial treatment for the nonunion.
