Disp fx of nk of 5th MC bone, l hand, subs for fx w nonunion

This code describes a fracture of the neck of the fifth metacarpal bone in the left hand, which is out of its normal alignment. The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

Use this code for a patient presenting for subsequent treatment of a displaced left fifth metacarpal neck fracture that has been diagnosed with nonunion. This applies to encounters for cast changes, physical therapy, medication management, or surgical planning specifically addressing the nonunion.

• Ensure documentation clearly specifies "displaced" and "nonunion" for the left fifth metacarpal neck.
• Confirm the encounter is for subsequent care, not the initial treatment or routine healing.
• Always review the full encounter documentation to capture any additional conditions or complications.
