Almost immediately after the state's insurance regulator earlier this month announced that rates for plans sold through MNsure would rise 4.5 percent on average, Republicans, health policy experts and other critics decried the figure as bogus and misleading.
The state Commerce Department has steadfastly defended the figure — a straight average of rate changes reported by the four returning carriers to MNsure — acknowledging that some consumers will see higher or lower rate changes. State agency officials said consumers can shop around once open enrollment begins Nov. 15 "to find the best option that fits their individual health and financial needs."
But other states, like California, Colorado and Washington, report their increases in premiums for their respective exchange plans as weighted averages.
Calculated that way, Minnesota's figure for next year is not 4.5 percent, but 11.8 percent.
A weighted average is considered by some experts to be a more accurate depiction of complex plans because it takes into account the percentage of enrollees distributed across the returning insurance carriers, which can have varying rates.
Commerce Department Commissioner Mike Rothman said Minnesota is unique because it saw the departure of PreferredOne from next year's exchange, an insurer that covered 60 percent of MNsure enrollees before it decided to pull out of the market. Moreover, Rothman said, Blue Plus, an HMO-plan and affiliate of Blue Cross, would be new to consumers once open enrollment begins.
"The Commerce Department put out a calculated straight average for people to be able to compare the average that was per company," Rothman said, listing the rate changes reported by the four returning firms, 1.8 percent, 8.1 percent, 17.2 percent and -9.1 percent.
The agency did this "so that people understood that for those companies going back, that that's what the average was, just straight up, that's what it was," Rothman said.
