These people are crooks. they contact me after receiving the referral from my doctor tell me that they have the prior authorization with no talk of copay or cost that they bill the insurance. They tell me to wear the test for 3 night to make sure they have the needed info. then they bill my insurance get paid then bill me for 1200.00 on top of it . after telling the cost were 280.00. Then after thanking has been addressed. they send it to collections and now sending to collections. and on top of that there test was wrong and had to be redone I share this hoping to save someone else the grief and humility of there dishonesty,
