The Obama administration has delayed a step crucial to the launch of the new healthcare law, the signing of final agreements with insurance plans to be sold on federal health insurance exchanges starting October 1. The U.S. Department of Health and Human Services (HHS) notified insurance companies on Tuesday that it would not sign final agreements with the plans between September 5 and 9, as originally anticipated, but would wait until mid-September instead, according to insurance industry sources.
