If someone have long term illness, or very bad accident that can be cost $50,000-$60,000 and much more, that is catastrophic. To pay your deductible + coinsurance to reach the (limit) of out of pocket cost for example $13,500.00, then 100% the insurance will pay for the balance.
I use $13,500.00 for my example because this is the maximum ACA allow for out of pocket cost to the people (I am not positive but I think is correct)
Go here https://www.healthcare.gov/apply-and-enroll/income-too-high-for-tax-credit/ and look what your income to family size to state show for if you can make your insurance lower. If your income is for example in NJ, and 3 people family and over the $80,000 than not apply.
So then you can go on that same link to ("Four ways you can buy a health plan" Click the drop bar to see "Plan Finder". Click on, then shop to compare.
The out-of-pocket for most professional corporate workers before Obamacare was ZERO.
Are you trying to claim that $13,500 is somehow good.
