The Obama administration said Friday that the enrollment records for roughly a quarter of all the people who signed up for health insurance on its website in October and November could contain errors, raising questions about whether those consumers would get coverage in time to pay for their medical care next month. Even now, the administration said, it may be sending incomplete or erroneous information to insurers for one in every 10 people who enroll. The disclosure added yet another complication to a long list of technical troubles that have hampered the rollout of President Obama's health care law.
