Multiple fx of ribs, right side, subs for fx w nonunion

This code signifies that a patient has sustained multiple rib fractures on the right side, and these fractures are failing to heal properly after the initial treatment. Nonunion indicates that the bone ends have not united and are not expected to heal without further intervention.

Apply this code when documentation confirms multiple right-sided rib fractures that are not healing as expected, and the patient is presenting for follow-up care related to this ongoing issue. This would be used for subsequent visits after the initial treatment, where nonunion has been identified and is being managed.

• Ensure documentation explicitly states "nonunion" for multiple right rib fractures.
• Verify that the encounter is for follow-up care, not the initial injury or routine healing.
• Do not use this code if the nonunion is for a single rib fracture; a more specific code would be required.
