Nondisp fx of triquetrum bone, unsp wrs, 7thK

This code signifies a triquetral bone fracture in an unspecified wrist that is not displaced and has progressed to a nonunion state. It indicates that the patient is in a subsequent phase of care for this specific fracture, where the bone has failed to heal properly.

Apply this code for follow-up encounters where a previously diagnosed, nondisplaced triquetral fracture in an unspecified wrist is documented as having nonunion. This is appropriate when the patient is receiving ongoing management for the unhealed fracture, such as for surgical planning or continued conservative treatment.

• Ensure documentation clearly states "nonunion" for the triquetral fracture.
• Verify the fracture is specifically of the triquetrum and not another carpal bone.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
