Nondisp oblique fx shaft of unsp ulna, 7thB

This code describes a fracture of the ulna, specifically a break in the shaft that is angled (oblique) but where the bone fragments remain in their normal alignment. It indicates that the skin and soft tissue surrounding the fracture have been breached, but the wound is relatively clean and small (Type I or II open fracture). This is the initial encounter for treatment.

Apply this code when documenting the initial treatment for an open oblique fracture of the ulnar shaft that is not displaced. This is appropriate for cases where the specific ulna (left or right) is not documented or cannot be determined. It is used for the first visit or admission related to this injury.

• Ensure documentation specifies "unspecified ulna" if laterality is not explicitly stated.
• Verify the fracture is indeed "nondisplaced" and "oblique" in the shaft.
• Confirm the open fracture type is I or II and that this is the initial encounter for care.
