Nondisp fx of triquetrum bone, unsp wrs, 7thP

This code signifies a fracture of the triquetrum bone in an unspecified wrist that was initially nondisplaced, but is now healing improperly. The patient is presenting for follow-up care related to this malunion, indicating the fracture has not healed in a functionally or anatomically correct position.

Apply this code when documentation confirms a previously diagnosed nondisplaced triquetrum fracture in an unspecified wrist is now exhibiting malunion. This is appropriate for subsequent encounters where the focus of treatment or evaluation is the ongoing management of the malunited fracture.

• Ensure the documentation explicitly states "malunion" and specifies the triquetrum bone.
• Verify the encounter is "subsequent" and not an initial treatment for the fracture.
• Confirm the wrist laterality is truly "unspecified" if not documented. If laterality is known, a more specific code should be used.
