There is no order of priority. Whichever one is reported first will do. However, social security does not include accidents. If the little finger fracture is caused by an accident, social security will not reimburse it. Social security will only reimburse the little finger fracture unless it is caused by a work-related injury. I hope this can help. If you have any questions about insurance, feel free to ask me, because I am from the insurance company.
