Government officials say Close — and other consumers who have received different subsidy amounts — probably made some mistake entering personal details such as income, age and even ZIP codes. The Associated Press interviewed insurance agents, health counselors and attorneys around the country who said they received varying subsidy amounts for the same consumers. [...] Centers for Medicare and Medicaid Services spokesman Aaron Albright said consumers "should feel confident that they received an accurate determination based on the information they provided in their application." About 87 percent of the more than 8 million people who signed up for coverage under the law received subsidies, which are paid directly to the insurance company on behalf of individual consumers, according to data from federal health officials. "Some of them got more of a subsidy, some of them got less," she said. Since consumers aren't required to use the entire amount, Charron said she encouraged her clients to accept at least $50 less than the highest subsidy quoted to give them a financial cushion in case the government ultimately decides that the lower amount applies. The differing subsidy calculations are part of a mountain of data conflicts affecting at least 2 million people who signed up for coverage in the new health insurance exchanges.
