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

This code signifies a break in the long, central part of the fourth metacarpal bone in the left hand. The bone fragments remain in their normal anatomical alignment, and the skin over the fracture site is intact. This injury is typically caused by direct trauma to the hand.

This code is appropriate for the initial visit for a patient presenting with a newly diagnosed, non-displaced fracture of the shaft of their left fourth metacarpal. It is used when the fracture has not broken through the skin, indicating a closed injury. Subsequent encounters for follow-up care or healing would require a different seventh character.

• Confirm the fracture is specifically of the shaft and not the head or base of the metacarpal.
• Verify the fracture is nondisplaced and located in the left hand.
• Ensure this is the initial encounter for treatment of this specific closed fracture.
