Nondisp seg fx shaft of r tibia, subs for clos fx w nonunion

This code signifies a follow-up encounter for a patient with a right tibia shaft fracture that involves multiple segments but remains in its natural anatomical alignment. Crucially, the fracture has failed to heal properly, indicating a nonunion complication.

This code is appropriate when a patient is receiving ongoing care for a previously diagnosed nondisplaced segmental fracture of the right tibial shaft, and the physician documents that the fracture has not united. This would be used for subsequent visits after the initial treatment, where nonunion is the primary focus of the encounter.

• Ensure documentation clearly states "nondisplaced," "segmental," and "nonunion" for the right tibia shaft.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
• Verify laterality (right tibia) is explicitly documented.
