DH and kids are on a BCBS-Wellmark plan. The deductible is $3400/year and everybody's costs count toward that (not $3400 for DH, another $3400 for DD13, etc.). Before we hit deductible we pay everything (except a yearly physical might be free, I think). After the deductible they pay everything.
This just went up to $321/month- it had been $289. I figure we can swing $3400 in health care/year if we have to- we never have spent close to that much yet, but it is there if anyone has a major illness.
I found it on their Wellmark website. I don't know if it is available in your state.
