Nondisp oblique fx shaft of unsp ulna, 7thC

This code describes a fracture of the shaft of the ulna that runs obliquely (at an angle) but where the bone fragments remain in their normal anatomical alignment. It specifically indicates an open fracture, meaning the skin and soft tissues are compromised, and the wound is extensive with significant soft tissue damage, periosteal stripping, or contamination (Gustilo-Anderson Type IIIA, IIIB, or IIIC). This is for the initial treatment of the injury.

Use this code for a patient presenting for the first time with an obliquely oriented fracture of the ulnar shaft that has not been surgically reduced or definitively treated. This applies when the fracture is documented as nondisplaced and the open nature of the injury meets the criteria for Gustilo-Anderson Type IIIA, IIIB, or IIIC.

• Confirm documentation explicitly states "nondisplaced" and "oblique" for the ulnar shaft fracture.
• Ensure the medical record clearly specifies the Gustilo-Anderson classification (Type IIIA, IIIB, or IIIC) for the open fracture.
• This "C" encounter code is only for the initial treatment phase; subsequent encounters will require different seventh characters.
