Bennett's fracture, right hand, init for opn fx

This code signifies an intra-articular fracture of the base of the right thumb metacarpal, extending into the carpometacarpal (CMC) joint, which is also an open fracture. An open fracture means there is a break in the skin and soft tissue, exposing the bone to the outside environment. This specific injury involves the right hand and is being treated for the first time.

Use this code for a patient presenting with a newly diagnosed Bennett's fracture of the right thumb metacarpal, where the fracture has broken through the skin. This applies to initial treatment encounters, such as emergency room visits, initial orthopedic consultations, or the first surgical repair of the open fracture. It is appropriate when the documentation clearly specifies an open fracture of the right hand.

• Ensure documentation explicitly states "open fracture" and specifies the "right hand" for accurate code assignment.
• Verify this is the initial encounter for treatment; subsequent encounters will require a different seventh character.
• Look for associated external wound documentation to support the "open fracture" designation.
