Nondisp fx of neck of first metacarpal bone, unsp hand, init

This code signifies a break in the neck of the first metacarpal bone (thumb) that has not shifted from its normal anatomical position. This injury affects the bone connecting the thumb to the wrist, without specifying which hand is involved.

This code is appropriate for the initial treatment of a closed fracture (skin intact) of the first metacarpal neck, where imaging confirms no displacement of the bone fragments. It is used when the specific hand affected is not documented or is unknown.

• Ensure documentation specifies "nondisplaced" and "closed fracture" for accurate code assignment.
• If the hand (left or right) is documented, a more specific code from the S62.25- series should be used.
• This code is only for the initial encounter; subsequent care would require a different seventh character.
