Health Care Insurance?

[jamal1984]

I'm 26 thinking of get a health care insurance before something really happen.
Newbie to this, don't know what to look for.
Visited healthcare.gov but can't find much.
Visited a few website and here is what i found.
Premium $187 a month with Calendar Year Deductible $1500.
What is Deductible and in network, out network?...
What am i look for?

Thank you
