My insurer requires 80% compliance to pay for the CPAP machine. I was required to submit a report to the hospital Bariatric program I am in & was told compliance was also at 80%. I didn’t ask if the program had separate compliance but I assume so as they are very strict & I also assume this report would be part of the records submitted for surgery approval.
Unclear if you have insurance involved but if you do, I would recommend you check with your insurer and/or HH company providing the machine. My insurance covers replacement parts, the mask I believe at 3 months. I would think if you are having issues with the mask, even if you are required to wait longer for a paid replacement, a better fitting or different model would be considered medically necessary.
I too am a stomach sleeper & have a full face mask at this time. It wakes me up when the air starts blowing in my eyes but I am able to readjust & go back to sleep. I feel for you!
