Nondisp transverse fx shaft of unsp fibula, 7thK

This code describes a specific type of fibula fracture where the break is straight across the bone shaft, but the bone fragments have not separated. It indicates a subsequent encounter for a fracture that is not healing properly (nonunion) and is being managed without surgical intervention to expose the fracture site.

This code is appropriate for follow-up visits where a patient with a previously diagnosed nondisplaced transverse fibular shaft fracture is being monitored for nonunion, and the fracture is being treated non-surgically (e.g., casting, bracing). It applies when the physician documents the ongoing management of the nonunion without an open procedure.

• Ensure documentation clearly specifies "nondisplaced," "transverse," and "shaft of fibula."
• Verify that the encounter is for a "subsequent encounter" and that "nonunion" is explicitly documented.
• Confirm that the treatment for the nonunion is "closed" (non-surgical).
