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

This code signifies a fracture of the lunate bone in the left wrist that has not displaced from its normal anatomical position. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone fragments have failed to heal together after a reasonable period.

This code is appropriate for documenting ongoing treatment for a left lunate fracture where the initial injury has been managed, but the bone has not successfully united. It would be used for office visits, follow-up imaging, or other interventions related to the persistent nonunion of the fracture.

• Ensure documentation clearly states "left wrist" and "lunate" to support laterality and specific bone.
• Verify that "nondisplaced" and "nonunion" are explicitly documented to justify these specific characteristics.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
