Displ seg fx shaft of humerus, unsp arm, init for opn fx

This code signifies a fracture of the humeral shaft that is both displaced and segmental, meaning the bone is broken into at least three pieces. The fracture is open, indicating a break in the skin that communicates with the fracture site, and the specific arm (left or right) is not documented. This is an initial encounter for treatment.

Apply this code for the initial treatment of a patient presenting with a newly diagnosed open, displaced, and segmental fracture of the humeral shaft where the laterality is unspecified. This is appropriate for the acute phase of care, including surgical repair or initial immobilization.

• Ensure documentation specifies "open" and "segmental" for accurate code assignment.
• Verify the encounter is "initial" for this specific fracture; subsequent encounters will use different seventh characters.
• Prioritize laterality if documented; only use "unspecified arm" when left or right is truly unknown.
