"The fact that a consumer has an inconsistency on their application does not mean there is a problem on their enrollment," said Bataille. "Most of the time what that means is that there is more up-to-date information that they need to provide to us."
The document provided to AP said that 2.1 million people enrolled through the new health insurance exchanges were "affected by one or more inconsistency" as of the end of April.

The exchanges offer subsidized private coverage to lower-income and middle-class people with no access to health care on the job. The sliding-scale subsidies are based on income and family size, and are also affected by where a person lives. Because they are structured as tax credits, the Internal Revenue Service can deduct any overpayments from a taxpayer's refund the following year.
Under the law, only citizens and legal immigrants are entitled to subsidized coverage.

Updated numbers provided by Bataille indicate that the total number of people affected remains about the same as a month ago. About 1.2 million have discrepancies related to income; 505,000 have issues with immigration data, and 461,000 have conflicts related to citizenship information.
The law contemplated there would be verification problems with the new program, and provided for a 90-day window to clear up discrepancies. During this time, a consumer's coverage is not affected.
