Oth fracture of oth metacarpal bone, init for opn fx

This code signifies a fracture of any metacarpal bone other than the first (thumb) metacarpal, where the skin and soft tissue overlying the fracture are broken, exposing the bone. This indicates an open injury to one of the long bones in the palm of the hand, excluding the thumb's metacarpal.

This code is appropriate for the initial treatment encounter of a patient presenting with an open fracture of the second, third, fourth, or fifth metacarpal. This includes scenarios such as a crush injury or direct trauma resulting in a visible wound communicating with the bone fracture.

• Ensure documentation specifies an "open" fracture and identifies the affected metacarpal as other than the first.
• This code is for the initial encounter; subsequent care will require different seventh characters.
• Always code the specific metacarpal if known (e.g., S62.32-S62.35 for specific metacarpals). Use this code when the specific metacarpal is not documented or is "other."
