Rising cost of health care: up 25 - 33% in one year?!?

I'm a self-employed IT contractor with a non-group health care insurance plan, so I make a monthly payment to the insurance company to cover my entire family (there are five of us). My current deductible is over $3,000, meaning the insurance company doesn't chip in on doctors visits until I've paid more than $3K, and that's YTD dollars. So my deductible payment balance starts over at $0 on 1 January. So far my monthly payment has been a little over $400/mo. which is manageable, and we didn't have to make too many deductible payments last year.

And then I got a letter from the insurance company. It seems the "rising cost of health care" is going to cost me an extra $200 per month, or I can increase my deductible to over $4,000 . So it looks like the cost of health care in the USA has increased by something like 25 - 33% in the last year.

WTF? Wouldn't an increase like this be news? Or is this unique to my insurance company? Am I being screwed? If so, I didn't even get dinner and drinks...
