Colorado is a good example how the healthcare reform law is working despite obstacles it has yet to even tackle, reports Bloomberg News. Out of 16 major cities, Denver's health insurance costs decreased the most--16 percent since implementation of the Affordable Care Act, according to a recent Kaiser Family Foundation study. "Premiums never go down," Larry Levitt, president of KFF, told Bloomberg. "It's almost like the laws of physics. But in Denver and some other places you have insurers competing for market share, and that's actually lowering premiums." Because the state expanded Medicaid, that has provided uninsured residents with health insurance. But a challenge the state faces is that nearly everything costs more in ski country. Article
