I think sleep studies are over rated and expensive compared to just giving them a CPAP and seeing if symptoms improve. For many, the sleep study takes a long time to schedule, doesn't always work, and as I mentioned terribly expensive.
The CPAP machine that I was prescribed would cost me $700 over three months to _rent_, which I would have to pay in advance, with reimbursement from my insurance plan only after I uploaded weekly compliance data dumps. Or, for an additional $200, the machine could upload those data dumps for me.
That's the real barrier for entry for most - cost.
But how much does a sleep study cost? Specialize doctors, specialized lab, specialized equipment: $700-$3000.
I got a better deal with my work's insurance plan: it would bill me for it if I didn't use it, and auto logged the data for me. That sounds ridiculous. Also my sleep study was just a unit I wore at home in my own bed. Seems cheaper than an in erson sleep study
