As part of our employment, our employer has negotiated that we pay $400 a month for my family to have insurance under these terms.

If I had a different employer, those terms could be wildly different. I would have no choice.

It is EXTREMELY complicated, and extremely different for everyone in the country, and depends heavily on how your employer sets up the benefits. This is a major benefit for large corporations, and a major burden for smaller businesses.

If you buy insurance through the private market, it is usually far more expensive, but often subsidized by the government, since you often only buy from the market if you are unemployed or low income.

~~They also contribute to their FSA which wasn’t really explained, so they did pay for that too~~

If you have insurance through your employer, then no the insurance company can’t raise your rates. And part of the reason for the Affordable Care Act (ACA, sometimes called Obamacare) was to make it so people who are getting the insurance themselves also can’t have their rates raised or get turned down for insurance because they have pre-existing conditions. However insurance companies can raise everyone’s rates when the insurance is up for renewal each year.

Most insurance plans have several different costs: 1. The monthly premium you pay to have insurance coverage. Some employers pay this themselves, otherwise it gets taken out of every pay check.

2. Co-pay: Usually a set amount ($30, for example) you pay to see a doctor for office appointments that aren’t an annual check-up*. So say I get an ear infection and see my primary doctor to get it treated, I’d pay the co-pay for that visit. Sometimes things like x-rays, blood work, CTs can be a set amount, other times it’s something like insurance will cover 65% of the cost. For some plans, co-pays are included when figuring out if you’ve reached your deductible.

3. Deductible: The amount you have to pay before “co-insurance” kicks in. Co-insurance being the percent of your bill insurance will pay (for us it’s 75% after we pay $3500 in a calendar year).

4. Out of pocket max: When you’ve spent this amount in a calendar year after that insurance covers 100%. Often plans have both individual and family maximums, with the family amount being higher.

Usually the more you pay in monthly premiums, the lower your deductible and out of pocket maximums will be. So each year people have to try and decide what they think their health bills will be next year when picking their plan (you can’t change plans mid-year unless something happens like changing job, getting married/divorced, having a kid). If you’re pretty healthy you might pick a lower monthly plan with higher out of pocket amounts because you don’t expect to have to pay much out of pocket. If you’re someone with a chronic condition or you’re expecting to need surgery or a costly treatment you might go with the higher monthly plan so you don’t have as high of out of pocket amounts.

For example, my spouse had to go to the ER a few years ago for what turned out to be a collapsed lung. They didn’t have to stay in the hospital overnight. I forget the total bill (or I’ve just blocked it from my memory), but our part ended up being about $5,000. Insurance kicked in after the bill got to $3,500, and they covered 75% of everything that was over $3,500. The most we would’ve paid was $6,000 (the individual out of pocket max), however we would still have to pay bills for myself and our kid up to $12,000 (family out of pocket max).

*Another part of the ACA was to make annual preventative screenings (like annual physical, mammogram for women over a certain age, prostate screening for men, etc) free.
