Of course you have to start with coverage in the zip code where you will select your residence.

Then narrow it down by the premiums and the deductibles that fit your financial situation.  The higher the deductible, the lower the premium, but you should be able to put at least the amount of the deductible into a Health Savings Account or be able to build up to it within the first few years.

Then, you'll want to make sure that the coverage you are considering has a nationwide network of "in network" health providers - not all of them do.  That may require a phone call to the "Help Desk" at ehealthinsurance.com or to the actual insurance company.

Then, on ehealthinsurance.com, there is an AM Best Rating under the insurance company names that come up when you do your search.

"The objective of the A.M. Best rating system is to provide an opinion as to an insurer's financial strength and ability to meet ongoing obligations to policyholders."

A+ & A++ are "Superior".

A- & A are "Excellent".

B+ & B++ are "Very Good".

And so on.  Just my opinion, but I wouldn't go with anything below an "A-".

Then, if it still looks like a tough choice, see which plans have "0% Co-insurance".  That means you won't have to pay ANY additional amounts once you meet your deductible as opposed to you having to pay 10%, 20%, 30%, etc. of the costs after you meet the deductible.

Also, some plans have preventative care provisions where you can get annual physicals, etc. where the deductible is waived.  In other words, you don't have to pay anything out of pocket for the covered preventative care visits.

Beyond that, it's sort of a shot in the dark.  But don't be afraid to change plans or even companies down the road.
