Displaced apophyseal fx r femur, subs for clos fx w nonunion

This code signifies a fracture occurring at the apophysis of the right femur, which is a growth plate or secondary ossification center. The fracture is displaced, meaning the bone fragments are not properly aligned, and the current encounter is for ongoing treatment of this closed fracture that has failed to heal properly (nonunion).

This code is appropriate for follow-up encounters where a patient is receiving care for a previously diagnosed displaced apophyseal fracture of the right femur that has not united. It specifically applies when the fracture is closed (skin intact) and the physician has documented nonunion. This would be used for subsequent visits for monitoring, cast changes, or planning further interventions for the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right femur and apophyseal location.
• Verify the encounter is "subsequent" and the fracture is "closed" to align with the 7th character "K".
• Do not use for initial treatment or for open fractures; different 7th characters would apply.
