Open enrollment has begun at my work for the 2016 year, and my company made some changes to providers and rates, so now I'm trying to sift through it all to make the best decision. I've been a 1099 before the end of last year so figuring out employer paid insurance is a whole different world for me... so I'm hoping you MMers can help me

Some basics about us:
-I'm 33
-H is on his own insurance through his work, and 100% of his premiums are paid by his employer, but if I get added on his deductible goes way up. He receives very expensive medical treatments every 2 months so it makes no sense for me to be on his plan.
-I rarely get sick enough to go to a doctor, and am not currently on any prescriptions. I get my annual obgyn visit done yearly.
-Monthly cash flow is my biggest issue, and I currently pay $42.46 per check for an HDHP plan.
-The biggest: We are starting to TTC so there's a high likelihood I will be having a baby in 2016. Once baby is here, he/she will be on my plan as well, but the goal is to attempt to have the baby towards the end of the year but I'm just focusing on individual care right now.
-I don't see any reason we'd be in out of network coverage since we live in a major metro area and rarely travel to far off places
The plan options:
Aetna HDHP:
Per paycheck premium: $24.21
Deductible: $5,000
CoInsurance: 20%
CoPay for non-preventative doctor visits: $25
Out of Pocket Limit: $5,000
Preventative Care: Paid 100%
HSA: Option to pay in, no employer contribution
Aetna Choice:
Per paycheck premium: $79.09
Deductible: $2,500
CoInsurance: 20%
CoPay for non-preventative doctor visits: $25
Out of Pocket Limit: $5,000
Preventative Care: Paid 100%
HSA: None
This plan has an HRA Health Fund that employer contributes $750.00 to, and I can add to it if I want. The money rolls over to next year but has a $3,000 cap.
Kaiser (we live very close to a Kaiser facility including hospital, but would be limited to only Kaiser facilities):
Per paycheck premium: $102.67
Deductible: $500
Co-Insurance: 20% depending on what it's for
Co-Pay: $20, and for prenatal it's 80% covered after deductible is met
Out of Pocket Max: $2,000
Preventative Care: 100% covered
FSA available
The Kaiser plan is super tempting, at least for baby-having, but that premium is pretty hefty and frankly I'm not sure I can afford that to come out of every check, and still keep up with my savings goals.
The two Aetna plans are pretty similar other than the deductible. I figured that it would take a year and a half of paying the lower premium to make up the deductible difference. But then that gets offset a bit by the $750 my employer contributes to the HRA.
So I guess the question is... pay now or pay later?
GAH.... any insight here, maybe from people who know roughly the cost of having a baby, assuming nothing crazy or out of the ordinary happens with that?
Re: Another insurance question (sorry long)
Just another set of numbers you may want to toss in there since you're planning for baby. If you and your husband were on the same plan, how would that work out with his treatments and the baby expenses? Depending on your numbers, it might be cheaper paying one set of deductibles than two.
You could then separate again the following year if that worked out.
Since she was born after January 1, but I was pregnant with her the majority of 2014, I had 2 deductibles and max OOP's to account for.

So I would find out how much adding a baby to your plan would cost. I always focus on the OOP max.

True. I've never had a baby, BUT every time we've had a bill through our hospital for something, I've called and asked if they offer a paid in full discount. Ours does 25%. Almost every medical bill I've gotten and asked for a paid in full discount, I have gotten one, but I've had to ask for it.
I 100% agree with you on this (and I know I'm also the minority not the majority on this board when it comes to separate finances). H's health insurance plan is significantly cheaper and better than the plans I'm offered thru work, but if I get put on it his bi-weekly insurance payment will double, so I'm hesitant to do it. If we go that route, which makes the most sense, I'm planning to set up an auto-pay to his account to cover my portion of the insurance.
I also agree fully with @kmurphy2131 I would not want to be limited to one hospital/provider. If there's a true emergency what happens if that's not the closest hospital to you? Or if another hospital is better equipped to handle to your case? Then you're stuck with a huge bill after the fact to deal with.
