Nondisp fx of shaft of first MC bone, right hand, init

This code signifies a break in the main body (shaft) of the first metacarpal bone (thumb) in the right hand, where the bone fragments remain in their normal alignment. It indicates that the skin over the fracture is intact, and this is the initial visit for treatment.

Use this code for a patient presenting with a newly diagnosed, non-displaced fracture of the shaft of the right thumb metacarpal. This applies to the initial encounter for evaluation and management of the closed fracture, such as casting or splinting.

• Ensure documentation specifies "nondisplaced" and "shaft" of the first metacarpal.
• Confirm the fracture is of the right hand and is a closed fracture.
• The "A" seventh character indicates the initial encounter for active treatment.
