Multiple fx of ribs, left side, subs for fx w delay heal

This code signifies that a patient has sustained multiple fractures to the ribs on their left side. The encounter being coded is a follow-up visit where the previously diagnosed fractures are not healing at the expected rate.

This code is appropriate for documenting a patient's visit for ongoing management of multiple left-sided rib fractures that are exhibiting delayed union. It would be used when the patient presents for re-evaluation, imaging, or treatment related to the slow healing process after the initial treatment phase.

• Ensure documentation clearly specifies "multiple" rib fractures and "left side."
• Confirm the encounter is for delayed healing, not initial treatment or routine follow-up of a healing fracture.
• Always assign additional codes for any associated injuries or complications.
