Oth fx first metacarpal bone, right hand, init for opn fx

This code signifies an open fracture of the first metacarpal bone in the right hand, which is not a Bennett's or Rolando's fracture. An open fracture indicates a break in the skin, exposing the bone or allowing communication between the fracture site and the external environment.

Apply this code for a patient presenting with an acute, non-Bennett's/Rolando's fracture of the right thumb metacarpal where the skin integrity has been compromised. This code is specifically for the initial treatment encounter for such an injury.

• Ensure documentation clearly specifies "open fracture" and the right hand.
• Verify this is the initial encounter for treatment of the fracture.
• Distinguish from Bennett's (S62.22-) and Rolando's (S62.23-) fractures, which have specific codes.
