Nondisp fx of shaft of 4th MC bone, r hand, init for opn fx

This code describes a break in the main body (shaft) of the fourth metacarpal bone in the right hand, where the bone fragments have not shifted out of alignment. It specifically indicates that the fracture is an open fracture, meaning there is a wound that communicates with the fracture site. This is the initial encounter for treatment of this injury.

Use this code for a patient presenting for the first time with an open fracture of the shaft of their right fourth metacarpal, confirmed by imaging, where the bone fragments remain in their anatomical position. This code is appropriate when the patient is receiving active treatment for the fracture, such as wound debridement, stabilization, or casting.

• Ensure documentation clearly specifies "nondisplaced" and "open fracture" of the fourth metacarpal shaft.
• Verify the laterality is "right hand" and the encounter is "initial" for active treatment.
• Always code associated open wound infections or complications separately.
