Unsp physl fx upper end of r fibula, subs for fx w nonunion

This code signifies an unspecific growth plate fracture located at the top portion of the right fibula. The "K" seventh character indicates that the patient is in a subsequent phase of care, and the fracture has failed to heal properly, resulting in a nonunion.

Apply this code for follow-up encounters where a patient is being treated for a previously diagnosed, unspecified physeal fracture of the upper right fibula that has not united. This would be used when the physician documents ongoing management of the nonunion, such as planning for revision surgery or continued conservative treatment for the unhealed fracture.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for this specific fracture.
• Verify the fracture location is the upper end of the right fibula and the type is physeal.
• Do not use for initial encounters or for fractures that have healed.
