Nondisp seg fx shaft of humerus, left arm, init for opn fx

This code signifies a fracture of the main part (shaft) of the left upper arm bone (humerus) that is broken into at least three pieces (segmental) but remains in its normal anatomical alignment (nondisplaced). The skin and soft tissues surrounding the fracture are compromised, exposing the bone to the outside environment, and this is the initial treatment encounter for this injury.

Apply this code for a patient presenting with an open, segmental, nondisplaced fracture of the left humeral shaft, such as from a high-impact trauma where the bone has pierced the skin. This code is appropriate for the initial surgical repair or emergency department visit for this specific injury.

• Confirm the laterality (left arm) and the open nature of the fracture.
• Ensure documentation specifies "segmental" and "nondisplaced" for the humeral shaft.
• This "B" encounter character is only for the initial treatment of the open fracture. Subsequent care will require a different encounter character.
