Nondisp fx of base of second MC bone, left hand, init

This code signifies a break at the very bottom (base) of the second metacarpal bone in the left hand. The fracture is stable, meaning the bone fragments have not shifted out of their normal alignment. This diagnosis is made during the patient's initial visit for this specific injury.

Apply this code for a patient presenting with a newly diagnosed, non-displaced fracture of the base of the second metacarpal in the left hand. This is appropriate for the initial treatment encounter, such as in an emergency department or orthopedic clinic setting. It is used when the skin over the fracture is intact (closed fracture).

• Ensure documentation explicitly states "nondisplaced" and "base of second metacarpal, left hand."
• Verify this is the patient's first encounter for this specific fracture.
• Confirm the fracture is closed; open fractures require different coding.
