Oth fracture of first metacarpal bone, right hand, init

This code signifies a fracture of the first metacarpal bone (thumb) in the right hand, excluding a Bennett's or Rolando's fracture. It indicates an acute injury where the skin over the fracture site remains intact (closed fracture).

Apply this code for new, non-displaced or displaced fractures of the right thumb metacarpal that are not specifically classified as Bennett's or Rolando's. This is appropriate for the initial treatment encounter for such an injury.

• Ensure the fracture is definitively located in the first metacarpal of the right hand.
• Confirm the fracture is closed and not an open fracture.
• Verify this is the patient's initial encounter for this specific injury. Subsequent care would use a different seventh character.
