Multiple fractures of ribs, bi, subs for fx w nonunion

This code signifies a patient presenting with multiple rib fractures affecting both sides of the rib cage. Crucially, the fractures have not healed properly, indicating a nonunion, and this encounter is for follow-up care or treatment related to this ongoing issue.

Apply this code when a patient with previously diagnosed bilateral multiple rib fractures is seen for management of a confirmed nonunion. This includes scenarios such as follow-up appointments, evaluation for surgical intervention, or ongoing conservative treatment for the unhealed fractures.

• Ensure documentation clearly specifies "multiple" ribs fractured and that the injury is "bilateral."
• Confirm that the encounter is for a "subsequent" visit and that "nonunion" of the fracture is explicitly documented.
• Do not use for initial treatment or for fractures that are healing normally.
