Disp fx of base of 3rd MC bone, r hand, 7thK

This code signifies a fracture at the base of the third metacarpal bone in the right hand that has shifted from its normal alignment. It specifically indicates that the patient is in a later phase of treatment where the fracture has failed to heal properly, resulting in a nonunion.

This code is appropriate for follow-up encounters with a patient who previously sustained a displaced fracture of the right third metacarpal base and is now presenting with evidence of nonunion. This would include situations where surgical intervention for nonunion is being planned or performed, or during ongoing management of a non-healing fracture.

• Always confirm laterality (right hand) and the specific bone (third metacarpal base).
• Ensure documentation clearly states "displaced" and "nonunion" for accurate code assignment.
• This "K" seventh character indicates a subsequent encounter for a fracture with nonunion; do not use for initial treatment or routine follow-up of a healing fracture.
