We paid our final IVF bill months ago and my last treatment from them was actually an ultrasound for pregnancy (which Should be covered by my insurance) and yet my insurance is denying everything coming out of the office pregnancy related and this doctor is in network. It's literally another 1,000 bucks.
No one prepared me for all of the hidden costs of fertility treatment. This is just insane...

I'm going to try to fight it, but I've never argued with insurance and won.

I also got a bill for blood tests recently which should have been covered with a small copay. The odd part of this was that it was from my RE--recall that I traveled for this last IVF--and I wasn't even in that city during the whole MONTH for which these tests had supposedly taken place. When I called, they realized it was an error and removed it.
This stuff is definitely annoying, not least because it means you have to spend a lot of time on hold. But if they should be covering it, keep calling! Sorry you're dealing with this.

I have sadly found that some doctors offices and hospitals prefer to just accept a rejection letter from an insurance company and go after the patient because the amount they can bill the patient is usually several times greater than what their agreed rate is with the insurance company.
I fought a $165 bill for my third beta blood test to confirm pregnancy for a loooong time. Apparently if it had been covered, my insurance would only have paid $13. But since they rejected the claim, the hospital felt they could just charge me the full amount (which sometimes they can, but my insurance had denied it as "Patient Responsibility: $0" which the hospital just chose to ignore and tried to bill me anyway). I had to threaten to report the hospital to the Better Business Bureau AND file a complaint with my insurance company for predatory billing unless they stopped harrassing me about a bill that was not my responsibility.
