Nondisp fx of base of oth metacarpal bone, init for clos fx

This code signifies a break at the bottom (base) of any metacarpal bone in the hand, excluding the thumb, where the bone fragments remain in their normal alignment. It indicates the initial treatment for a closed fracture, meaning the skin over the fracture is intact.

Apply this code for patients presenting with a newly diagnosed, non-displaced fracture at the base of the second, third, fourth, or fifth metacarpal bone. This is appropriate for the initial visit where definitive treatment, such as splinting or casting, is initiated.

• Ensure documentation specifies "nondisplaced" and "base of metacarpal" (excluding the thumb) for accurate selection.
• Confirm this is the patient's first encounter for this specific injury.
• Verify the fracture is closed; if open, a different code is required.
