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

This code signifies a break in the neck of the fourth metacarpal bone in the right hand, which has not shifted from its normal anatomical position. Importantly, this fracture is an open type, meaning the skin and soft tissue have been compromised, exposing the bone to the outside environment. This code is used for the initial treatment of such an injury.

Apply this code when documenting the first encounter for a patient presenting with a "boxer's fracture" of the right fourth metacarpal, where the fracture fragments remain aligned. This is specifically for cases where there is an associated wound communicating with the fracture site, indicating an open fracture. It is appropriate for the initial surgical repair or non-surgical management of this specific injury.

• Ensure documentation clearly specifies "right hand" and "fourth metacarpal" to differentiate from other metacarpals or the left hand.
• Confirm the fracture is explicitly documented as "nondisplaced" and "open" to support the use of this specific code.
• The "B" seventh character indicates an initial encounter for an open fracture, so subsequent care would require a different seventh character.
