Nondisp fx of nk of 2nd MC bone, l hand, 7thK

This code signifies a fracture of the neck of the second metacarpal bone in the left hand that has not shifted from its anatomical position. The fracture, however, has failed to heal properly, resulting in a nonunion. This specific code is used when the patient is receiving follow-up care for this unhealed fracture.

This code is appropriate for subsequent encounters when a patient is being treated for a previously diagnosed, nondisplaced fracture of the left second metacarpal neck that has progressed to a nonunion. This includes visits for ongoing management, evaluation of nonunion, or preparation for surgical intervention to address the nonunion. It would not be used for the initial fracture treatment or for a fracture that is healing normally.

• Ensure documentation clearly states "nonunion" and specifies the left hand and second metacarpal neck.
• Verify the fracture is explicitly documented as "nondisplaced."
• This "K" seventh character indicates a subsequent encounter for a fracture with nonunion; do not use for initial treatment or routine healing.
