Nondisp fx of base of 3rd MC bone, l hand, 7thK

This code signifies a fracture at the base of the third metacarpal bone in the left hand that has not shifted from its original position. The "K" seventh character indicates that the patient is receiving care for a complication where the bone fragments have failed to heal together after an initial treatment.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed nondisplaced fracture of the left third metacarpal base, and the physician has documented nonunion as a current complication. This would include scenarios such as surgical intervention for nonunion or ongoing conservative management specifically addressing the nonunion.

• Ensure documentation clearly states "nondisplaced" and "nonunion" for the left third metacarpal base.
• Verify this is a subsequent encounter for the fracture, not the initial treatment.
• Confirm the laterality is "left hand" and the specific bone is the "third metacarpal."
