My last thing that I need to do before being approved by insurance company is to get my cpap machine and see the pulmonary doctor on Tuesday. At first, his office said that I would need to be monitored for 30 days before I could even be approved for surgery. When I called my surgeon's office, they said that as long as I had initially seen the pulmonary doctor and was using the cpap machine, they would send request for surgery in. I did not have to wait another 30 days. My question is, how does the pulmonary doctor monitor you on the machine? Can they take readings on it while I am at home? A bit confused! I am praying I get a surgery date of early April! Fingers crossed!!!!
