Displ seg fx shaft of humer, l arm, subs for fx w routn heal

This code signifies a left humerus shaft fracture that is segmental and displaced, meaning the bone is broken in at least three pieces and the ends are not properly aligned. The "D" indicates this is a subsequent encounter for a fracture that is healing routinely, without complications.

This code is appropriate for follow-up visits where a patient is receiving ongoing care for a left segmental humerus shaft fracture that is healing as expected. It would be used after the initial treatment phase, during the period of routine follow-up and monitoring of fracture consolidation.

• Ensure the documentation specifies a left humerus and a segmental fracture pattern.
• The "D" seventh character is for subsequent encounters with routine healing; use "A" for initial encounters and other characters for delayed/nonunion or malunion.
• Verify laterality (left vs. right) is clearly documented to avoid coding errors.
