I had similar markups at my sleep doctor. It was funny because a $20 part from Amazon would be sold for $200 and end up costing $50 for me after my insurance co-pay.

At first they were real pissy about me buying things from third parties but eventually just gave me the part list and stopped mentioning how I never bought stuff from them.

Is it actually cheaper to get everything somewhere else? My test is covered by the doctor but they would charge like $1k for the device if I wanted it which is where I was anchored.

Would you mind sharing where I can get the testing apparatus for cheaper?

Any online marketplace if you search for the keywords mouthpiece snoring. Warning, as you will see in the reviews, that wearing a poorly fitted one for extended periods of time will affect your bite since it does dislocate your jaw. YMMV but that should explain why a proper qualified dentist can make you a fitted one for $1k

A dentist will charge $2k+

There are a range of treatment options out there, and we focus on FDA-cleared devices that are supported by clinical efficacy studies.

They’re scamming insurance companies
