I list one: Norco, Inc. at 440 30Th St. It is enrolled with Medicare to supply CPAP machines.
I don't list another CPAP supplier within 100 miles of Elko.
The supplier I list in Elko is enrolled with Medicare to supply home medical equipment. I checked its address and phone number against Medicare's supplier file.
Medicare also lists it for BiPAP machines and oxygen. A BiPAP machine is like a CPAP, but it uses two levels of air pressure.
Being listed here is not a recommendation. It also doesn't mean a supplier takes your plan. Call to check what they accept and what they have in stock. This site is free for patients.
