Medicare DME requirements
Any Physician can write an order for CPAP, BIPAP, or oxygen. It does not require a sleep disorder specialist. Medicare requires the ordering Physician to fill out a form once yearly justifying the continued need for CPAP or oxygen. In fact, they are required to attempt to titrate before continuing the order. That is the likely reason your new Physician will not accept a sleep study that is two years old. He will probably require you to have a new sleep study or order an overnight oximetry in your home by a local oxygen company.
