Nondisp seg fx shaft of ulna, unsp arm, 7thB

This code describes a fracture of the ulna bone in the forearm that is broken in at least two places (segmental) but the bone fragments remain in their normal anatomical alignment (nondisplaced). It specifically indicates that the skin was broken, exposing the bone, and the wound is relatively clean (Type I or II open fracture).

This code is appropriate for the initial treatment of a patient presenting with a segmental, nondisplaced open ulna shaft fracture where the arm involved is not specified. It is used when the open fracture is classified as Gustilo-Anderson Type I or II, indicating a less severe open wound.

• Ensure documentation specifies "segmental" and "nondisplaced" for the ulna shaft fracture.
• Confirm the open fracture type (Gustilo-Anderson I or II) is clearly documented by the provider.
• This "B" encounter code is only for the initial treatment phase; subsequent encounters will require different seventh characters.
