ACA plans absolutely cover childbirth (https://www.healthcare.gov/what-if-im-pregnant-or-plan-to-ge...). But it might not matter because you aren't on a marketplace plan according to the screenshots in your post.
You are on this plan: https://www.trinetaetna.com/pdfs/Aetna_PPO_7150.pdf
Which does cover childbirth according to page 3. And has a 7150 deductible per person - the $14300 is the family out of pocket max, so the childbirth should top out at the 7150. Other expenses might put you at the same 40K cost for the year, but not the childbirth alone.

that link doesn't even say what you says it does - it said you can apply for coverage, not that there are plans that cover child birth. Have you never done this before?
> the $14300 is the family out of pocket max
You know they charge you, separately, for both the mother's care AND the infant's during a delivery right? Those count as two people. I am, with 100% certainty, going to hit the out of pocket max - I have every time.
Like I've paid for three kids all on the same plan, including one born in January so my deductible got spread over two different billing years.
I have to ask - why are you defending this?
