AAFE Alert! As of June 2015, dentists have to either be opted in or opted out of Medicare if you prescribe medications to Medicare patients. Before you make this very important decision, you need to decide if you will bill Medicare for bruxism and dental sleep medicine oral appliances. The wrong decision will lock you out for years and cost you tens of thousands of dollars in lost revenue and lost patients. You need to take action now! AAFE has partnered with STATDDS to provide Medicare Enrollment Services.
