With health insurance marketplaces about to open for 2015 enrollment, the Obama administration has told insurance companies that it will delay requirements for them to disclose data on the number of people enrolled, the number of claims denied and the costs to consumers for specific services. For months, insurers have been asking the administration if they had to comply with two sections of the Affordable Care Act that require "transparency in coverage." In a bulletin sent to insurers last week, the administration said, "We do not intend to enforce the transparency requirements until we provide further guidance." Administration officials said the government and insurers needed more time to collect and analyze the data.
