My wife worked with Braverman. We have OON benefits, but none covered the big fees (new patient registration, IVF management [immune protocol - we were at Cornell for IVF], and pregnancy management). If you have OON benefits, they will take whatever insurance pays for office visits, ultrasound, etc. but don’t charge you if there is a remaining balance after insurance payments.
All told we paid about 15k plus just for his services. I’ve appealed the denied claims for the aforementioned services with no luck. A few women (like literally two or three) in our online support group have had luck with coverage for these fees, but 95% of us just come OOP for it. Luckily my insurance covered IVF - otherwise we couldn’t have afforded him. We do have a 9 month old rainbow baby to show for it all, so despite the cost, I would do it all over again to get where we are now.
