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

This code signifies a right-hand injury involving a displaced fracture of the neck of the second metacarpal bone. The "nonunion" aspect indicates that the bone fragments have failed to heal together after a previous attempt at fracture management. This diagnosis is made during a subsequent encounter for ongoing care related to this specific healing complication.

Use this code for patients presenting for follow-up care of a previously treated right second metacarpal neck fracture that has not healed. This applies when imaging confirms displacement and a lack of bony union, and the patient is undergoing continued management for this specific complication. It is appropriate for encounters where the focus is on addressing the nonunion.

• Ensure documentation clearly specifies "nonunion" and "displaced" for the right second metacarpal neck fracture.
• Verify this is a subsequent encounter, not an initial treatment for the fracture.
• Confirm laterality (right hand) and the specific bone (second metacarpal) are accurately documented.
