Are you providing Oral Appliance Therapy for sleep apnea to your Medicare patients? In order to bill Medicare and have your patients use their Medicare benefits, you must enroll in Medicare as a DME supplier. Yes, dentists are considered DME or Durable Medical Equipment suppliers for the delivery of oral appliances. The process is long and tedious. Chose this option if you would like us to direct you and complete the application for your office. Remember, this does not include the fee you will owe Medicare which is currently $544. These fee's are non-refundable.
