Nondisp fx of lunate, left wrist, subs for fx w malunion

This code describes a left wrist injury involving a lunate bone fracture that is not displaced, meaning the bone fragments are still in their normal anatomical alignment. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "malunion" specifies that the fracture has healed, but in an unsatisfactory position or alignment.

Apply this code when documenting follow-up care for a patient with a previously diagnosed nondisplaced lunate fracture of the left wrist that has healed incorrectly. This would include scenarios where the malunion is being monitored, or the patient is undergoing treatment or evaluation related to the malunion.

• Ensure documentation clearly specifies "left wrist" and "nondisplaced" for the lunate fracture.
• Verify that the encounter is for follow-up care and not the initial treatment of the fracture.
• Confirm that the physician's notes explicitly state or imply a "malunion" of the fracture.
