Displ spiral fx shaft of humer, unsp arm, 7thK

This code signifies a spiral fracture of the main shaft of the humerus that has shifted out of alignment and is not healing properly. The injury is located in an unspecified arm, and the patient is presenting for follow-up care related to this ongoing healing complication.

Apply this code when documentation confirms a patient is being seen for a previously diagnosed displaced spiral humerus shaft fracture that has failed to unite. This is appropriate for subsequent visits where nonunion is the primary focus of treatment or evaluation, such as for surgical planning for bone grafting or revision fixation.

• Ensure documentation explicitly states "nonunion" for the fracture.
• Verify the fracture is specifically a "spiral" type and located in the "shaft" of the humerus.
• Confirm this is a subsequent encounter for the fracture, not the initial treatment.
