Nondisp fx of neck of fourth MC bone, left hand, init

This code signifies a break in the neck of the fourth metacarpal bone in the left hand, which has not resulted in the bone fragments being out of alignment. It specifically indicates that this is the first time the fracture is being treated. This type of fracture is often referred to as a "boxer's fracture" if it affects the fifth metacarpal, but in this case, it's the fourth.

Use this code for patients presenting with a newly diagnosed, non-displaced fracture of the neck of the fourth metacarpal bone in the left hand. This applies to the initial treatment phase, such as casting or splinting. It is appropriate when the fracture is managed conservatively without surgical intervention to realign bone fragments.

• Ensure the laterality (left hand) and the specific bone (fourth metacarpal neck) are accurately documented.
• Verify that the fracture is indeed nondisplaced and that this is the initial encounter for treatment.
• Do not use this code for subsequent encounters or if the fracture is displaced.
