From what I've gathered, VISTA members all have SevenCorners healthcare coverage, but State and National members get healthcare through their site or other sponsoring agency. If you're State or National, you probably need to talk to the agency that got the grant to have you if you want to get any info on your insurance.

The VISTA coverage isn't great, but it'll get you through routine stuff. The $5 copay is nice. I've never had to do any extra paperwork, my doctor's office just submits the claims and gets paid. Also, I've never had to pay a dime for a prescription medication as long as I get the generic.
