Displ seg fx shaft of humer, r arm, subs for fx w delay heal

This code signifies a fracture of the main part of the right upper arm bone that has broken into multiple pieces and is no longer aligned. The patient is in a later stage of care for this injury, and the bone is not healing at the expected rate.

Apply this code for follow-up encounters where a patient with a previously diagnosed displaced segmental fracture of the right humeral shaft is being treated for delayed union. This includes situations where additional interventions or monitoring are required due to the slow healing process.

• Ensure documentation clearly specifies "right" arm and "segmental" fracture.
• Verify the encounter is for "delayed healing" and not routine follow-up or nonunion.
• Confirm the fracture was initially "displaced" and is of the "shaft" of the humerus.
