Oth disp fx of base of first MC bone, right hand, init

This code signifies a break in the base of the first metacarpal bone (thumb) on the right hand, where the bone fragments are no longer in their normal alignment. It specifically applies to fractures that have not broken through the skin and are being treated for the first time.

Apply this code for a patient presenting with a newly diagnosed, non-open fracture at the base of the right first metacarpal, where imaging confirms displacement of the bone fragments. This is appropriate for the initial evaluation and management of such an injury.

• Ensure documentation specifies "displaced" and "closed" for accurate code assignment.
• Verify the laterality (right hand) and the specific bone (first metacarpal base).
• The "A" seventh character indicates an initial encounter for active treatment of the fracture.
