Disp fx of neck of unsp MC bone, subs for fx w routn heal

This code signifies a fracture of the neck of an unspecified metacarpal bone that is no longer in its anatomical alignment (displaced). The patient is currently in a phase of routine healing following the initial treatment of this fracture.

This code is appropriate for follow-up encounters where a patient is receiving ongoing care for a previously diagnosed and treated displaced metacarpal neck fracture, and the healing process is progressing as expected without complications. It would be used after the initial treatment encounter but before the fracture is fully healed.

• Ensure documentation specifies "displaced" and that the encounter is for subsequent care with routine healing.
• Verify that the specific metacarpal bone is not identified in the documentation, as this code is for an "unspecified" metacarpal.
• Do not use for initial treatment, malunion, nonunion, or delayed healing; separate codes exist for those scenarios.
