Nondisp fx of lunate, right wrist, subs for fx w nonunion

This code describes a fracture of the lunate bone in the right wrist that is not displaced, meaning the bone fragments are still in their normal anatomical position. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and the "nonunion" specifies that the bone is failing to heal properly.

Use this code when a patient presents for ongoing treatment of a previously diagnosed, nondisplaced lunate fracture in the right wrist, and there is documentation indicating that the fracture has not united or is showing signs of delayed healing. This would apply to scenarios such as follow-up appointments for casting, bracing, or surgical planning due to nonunion.

• Ensure documentation clearly states "nondisplaced" and specifies the "right" wrist.
• Verify that the encounter is for follow-up care of the fracture, not the initial treatment.
• Confirm that the physician's notes explicitly mention "nonunion" or a similar term indicating healing failure.
