Insurance is not a monolithic deal, every policy can be written differently. Many companies have two or three choices, some offer much better coverage to the executives then to the rank and file. (or, like one company I worked for they offered the executive coverage to the rest of us, but there was no way we could have paid for it, it would have been about 1/3 of my check, so Hello Kaiser.) Those choice can be changed like once a year, so once you sign, you are stuck. So it would pay to really read the fine print about the coverage first. Also, I bet you will not even be eligible to sign up until you've hit the end of the 90 day trail period, but you should check on that.
