Displ commnt fx shaft of ulna, r arm, 7thB

This code signifies a severe break in the right ulna, specifically in the shaft, where the bone is shattered into multiple fragments and the pieces are no longer in their normal alignment. It also indicates that the fracture has broken through the skin, but the wound is relatively clean and small (Type I or II open fracture).

This code is appropriate for the initial treatment of a patient presenting with a right ulnar shaft fracture that is both comminuted and displaced, and where the fracture has created an open wound of Type I or II severity. It should be used for the first encounter where definitive treatment for this specific injury is provided.

• Ensure documentation clearly specifies "right arm" and "ulna shaft" to differentiate from other forearm bones or locations.
• Verify the "displaced" and "comminuted" nature of the fracture, as well as the "open" status and Gustilo-Anderson classification (Type I or II).
• This "B" seventh character is exclusively for the initial encounter for open fractures; subsequent encounters will require different seventh characters.
