Multiple fractures of ribs, bi, subs for fx w delay heal

This code signifies a patient presenting with multiple rib fractures on both sides of the chest (bilateral) that are not healing as expected. It indicates a follow-up visit where the primary concern is the ongoing, slower-than-normal healing process of these previously diagnosed fractures.

Use this code for encounters where a patient with documented bilateral multiple rib fractures is being evaluated for delayed union or non-union. This typically applies to follow-up appointments after the initial injury and acute treatment, where the focus is on monitoring healing progress and managing complications related to slow healing.

• Ensure documentation clearly specifies "multiple" ribs and "bilateral" involvement.
• Confirm the encounter is for a subsequent visit and explicitly addresses delayed healing.
• Pair with external cause codes (V00-Y99) if the cause of the original injury is still relevant and documented.
