Disp fx of nk of 2nd MC bone, l hand, subs for fx w nonunion

This code describes a fracture of the neck of the second metacarpal bone in the left hand that has shifted out of its normal alignment and has failed to heal properly. The "subsequent encounter" indicates that the patient is receiving ongoing care for this unhealed fracture.

Use this code for follow-up visits where a patient is being treated for a previously diagnosed displaced fracture of the left second metacarpal neck that has not united. This includes scenarios such as continued conservative management, evaluation for surgical intervention for nonunion, or post-operative care for a procedure addressing the nonunion.

• Requires a 7th character "K" for subsequent encounter for fracture with nonunion.
• Ensure documentation clearly states "displaced" and specifies the "neck" of the second metacarpal.
• Confirm the laterality is "left hand" to accurately apply this code.
