Disp fx of neck of first metacarpal bone, right hand, init

This code signifies a break in the neck of the first metacarpal bone (thumb) in the right hand, where the bone fragments are no longer in their normal alignment. It specifically indicates that this is the initial treatment encounter for a fracture that has not broken through the skin.

Apply this code for patients presenting with a newly diagnosed, displaced fracture of the right thumb metacarpal neck, treated with closed reduction or immobilization without surgical incision. This is appropriate for the first visit where definitive treatment for the fracture is initiated.

• Ensure documentation specifies "displaced" and "right hand" for accurate code assignment.
• Verify that the encounter is indeed the "initial encounter" for this specific fracture.
• Confirm the fracture is "closed" (skin intact) to differentiate from open fractures.
