$46 a month for four of us. No deductible...drugs are free if I get them on base; at most it will cost $9 out in town for meds.
Hospital stays are $25 copay for everything, including surgery, anesthesiologist, RNs, etc. Doctors visits in town cost $12.
I've had two back surgeries, one neck surgery, two ankle surgeries, two knee surgeries, and some other stuff done by outside docs. Never paid a dime of money, other than what is mentioned above.
Inital buy in, however, was expensive in a sense.
