Insanely high genetic testing bill (Kaiser Georgia)

As the title says, we got a $4500 bill for 2 genetic screening tests we did back in June. No one at the office told us how much it would cost, and they told us we really should do it since my wife is considered a “high risk pregnancy” (over 35).

I tried appealing the bill, requesting to pay directly to the diagnostic company, however Kaiser is telling me they performed the test.

On the bill it states that the test was performed at the Quest Diagnostics lab in VA, however first Kaiser representative said test was performed at Kaiser, and the second one told me Quest is contracted by Kaiser. However, Quest diagnostics representative said they are not partners with Kaiser, and they couldn’t find my wife’s name or dob in their database at all.

We have a high deductible plan from my employer (bronze+), but even the doctor at the office said those tests are usually covered. I guess my plan just happen to not be covering it at all.

Is there anything I can do at all? I looked up online, and seems cash price for those test is a few hundred dollars at max, it frustrates me to no end that I’m paying x10 of the price, and there seem to be no way to contest it at all.
