The federal government will check income claims by individuals applying for subsidies under Obamacare and remains on track to open the health insurance exchanges it will operate on Oct. 1, the main administrator of the exchanges said this week.

Writing in a Health and Human Services website blog, Marilyn Tavenner, administrator of the Centers for Medicare & Medicaid Services, said she was hoping to clear up "mischaracterizations" and "confusion" that arose in the wake of the employer mandate postponement and coverage about final regulations CMS released Friday on eligibility for the exchanges.

In that announcement Friday, the administration said it would significantly scale back the law's requirements that the new exchanges verify consumers' income and health insurance status until 2015, when stronger verification systems are in place.
