That's why factcheck should not be used to check... facts. Just as they claim the RNC have twisted this and that to make themselves looks better factcheck is twisting things here as well, to make someone else look better. Health insurance providers had raised premiums in anticipation of the vote and the legislation passing. So it's specifically important to look not at 2010 when it was signed into law but a few years below when there was this uncertainty about it. One way market deal with uncertainty is to hedge their bets. "Not sure what will happen, but this might pass, and why don't we just raise the rate now" kind of idea.
I've heard this directly from the health insurance representative who came and told us told us, "sorry but rates are going up sharply because we anticipate this new legislation".
But they did during 2009. By July, a number of bills were already approved by committees in the House. And the Fall is usually when the companies get prices for the next year. So it went up sharply then. Then in again in 2010. Price is not always comparable because the level of coverage had also changed. We had to get new plans and while they covered some mandatory free procedures and didn't have lifetime maximum, they had also bigger deductibles and a reduction in options and procedures covered.
That doesn't mean we'll find a larger jump there, I found it for my self, but the KFF study shows there wasn't in general. However discarding date legislation has passed is also dishonest as factcheck did. Companies which are affected by regulations monitor them closely and adjust to them correspondingly.
Without adjusting for inflation, this growth is ~60% growth in 6 years, or a doubling time of ~9 years. After adjusting, it's more like 40% over the same 6 years or a doubling time of ~12 years.
