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

This code signifies a fracture at the base of a metacarpal bone, excluding the thumb (first metacarpal), where the bone fragments are not properly aligned. It specifically indicates that this is the initial treatment for a fracture that has not broken through the skin.

Apply this code when a patient presents with a newly diagnosed, displaced fracture at the base of the second, third, fourth, or fifth metacarpal. This is appropriate for the initial encounter where definitive treatment, such as reduction and casting, is being performed for a closed fracture.

• Ensure the fracture is specifically at the base of the metacarpal and not the shaft or head.
• Verify the fracture is displaced and not a non-displaced fracture (S62.317A).
• Confirm this is the initial encounter for treatment; subsequent care will use different seventh characters.
