Thanks for all of the replies here, I appreciate all of the insight. I think you all must be right in that my insurance isn't as great as I thought. Before we got married, my wife was on an Obamacare plan that was costing her 5x as much as our current insurance, and it was a catastrophic plan with a very high deductible and poor coverage even after meeting the deductible. So when she was able to join mine (Blue Cross Blue Shield), it was comparatively a big step up in coverage. But apparently it's not as great as we thought.
I had my appendectomy on New Year's Eve (December 31, 2016) at an in-network hospital. I left the hospital on January 1, 2017. I was billed over $30,000 for the appendectomy which included a relatively minor surgery and less than 24 hours of hospital care. There were no complications or infections--it was all textbook. I hit my $1,750 deductible, and then insurance kicked in at 70% / 30%. My 30% of the bill resulted in hitting the out of pocket max of $7,150.
However, our insurance benefit year spans from May 1 - April 30 of each year, so none of the appendectomy payment counts towards the pregnancy. So even though our max out of pocket is $14,300, the timing of everything is what's going to put us over $21,000 in a period of one year.
There is of course the chance that the pregnancy will not cost as much as I'm anticipating. But I've lost all faith in hospital billing and have assumed the birth is going to cost over $24,000, at which point it wouldn't matter if the birth costs $24,000 or $240,000--we would still hit our OOP max. The average childbirth hospital bill ranges from $4,000 - $37,000 for vaginal delivery, and $8,000 - $71,000 for a c-section, so I was basing my numbers off those. The surgery scheduled for after the birth is relatively minor, but I also thought an appendectomy was minor and that was still a $30,000+ procedure. That's why I'm assuming we'll be hitting our $14,300 OOP max. Perhaps we'll get lucky and the hospital charges will be less than anticipated.
As for the $14,300 max OOP, we just received a prenatal care bill and letter in the mail last night from Blue Cross Blue Shield stating, "$1,002.35 has been applied to your $14,300.00 program in network out-of-pocket limit." That's what caused me to start this thread.
