Nondisp fx of shaft of 2nd MC bone, r hand, 7thK

This code signifies a fracture of the shaft of the second metacarpal bone in the right hand that has not displaced, meaning the bone fragments are still in their normal anatomical alignment. The "subsequent encounter for fracture with nonunion" indicates that the patient is receiving ongoing care for this fracture, and it has failed to heal properly within the expected timeframe.

This code is appropriate for follow-up visits where a patient with a previously diagnosed, nondisplaced right second metacarpal shaft fracture is being treated for a nonunion. This includes evaluations, imaging, or discussions regarding further interventions for the unhealed fracture. It would not be used for the initial injury or for a fracture that is healing normally.

• Ensure documentation clearly states "nonunion" and specifies the right second metacarpal shaft.
• Verify the fracture is nondisplaced; displaced fractures would require a different code.
• This code is for subsequent encounters; use an initial encounter code for the acute injury.
