Disp fx of triquetrum bone, unsp wrs, subs for fx w malunion

This code describes a triquetral bone fracture in an unspecified wrist that was initially displaced but has since healed improperly, resulting in a malunion. The patient is presenting for follow-up care related to this previously treated, but now malunited, fracture.

Use this code for a patient encounter where the primary reason for the visit is the management or assessment of a malunited displaced triquetral fracture of an unspecified wrist. This typically applies to follow-up appointments after initial treatment, where imaging or clinical examination confirms the fracture has healed in an anatomically incorrect position.

• Ensure documentation clearly specifies "malunion" and that the fracture was initially "displaced."
• Verify the encounter is for subsequent care of the malunion, not the initial treatment of the acute fracture.
• Confirm the fracture location is the triquetrum and the wrist is unspecified (e.g., laterality not documented).
