Unsp physeal fx upper end of l femur, subs for fx w nonunion

This code signifies an unspecified growth plate fracture in the upper part of the left thigh bone that has failed to heal properly. It indicates that the patient is presenting for ongoing treatment of this nonunion. The "unspecified" nature means the specific type of physeal fracture (e.g., Salter-Harris type) was not documented.

Use this code when a patient is seen for follow-up care of a previously diagnosed physeal fracture of the proximal left femur that has not united. This applies to situations where surgical intervention for nonunion, casting, or other non-operative management of the nonunion is being provided. It is appropriate for any encounter after the initial treatment of the fracture, specifically addressing the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the left femur's upper end.
• This code is for subsequent encounters only; do not use for the initial treatment of the fracture.
• Verify laterality (left) is explicitly documented to support this specific code.
