Nondisp fx of neck of oth metacarpal bone, init for opn fx

This code signifies a break in the neck of a metacarpal bone, excluding the thumb, where the bone fragments remain in their normal anatomical alignment. The fracture is open, meaning there is a break in the skin communicating with the fracture site. This code is specifically for the initial treatment of such an injury.

Apply this code for patients presenting with a newly diagnosed open, nondisplaced fracture of the neck of any metacarpal bone other than the first (thumb). This would include injuries resulting from direct trauma to the hand, such as a punch or fall, where the skin is compromised. It is used when the patient is receiving active treatment for the fracture.

• Ensure documentation clearly specifies "nondisplaced" and "open fracture" for the neck of a metacarpal other than the thumb.
• Confirm this is the initial encounter for active treatment; subsequent encounters will require different seventh characters.
• Always code any associated external wound or infection separately if documented.
