If your claim for emergency care is refused by your health plan, what would be the best thing to do? Filing an appeal with your health plan is the best step to take, and if you continue to get denied, persevere. In some states, the complaint eventually goes before a committee outside the plan which may reverse the denial after assessing the claim information differently. You may also file a complaint to the officials who manage your health plan. If your plan is funded by your employer, it is regulated by the U.S. Department of Labor. Otherwise, your state insurance department would be in charge, and has a complaint procedure that will investigate your problem.
