HC Reform Update from Mark Sanna: Highly anticipated regulations defining what constitutes "unreasonable" health insurance premium increases are expected any day now that federal regulators have sent them to the Office of Management and Budget for final review. Democrats' health care reform law gives the federal government greater oversight of health insurance premium increases by requiring a review and justification of steep increases. The law requires health plans to publicly justify "unreasonable" rate hikes starting with 2010 plan years, and gives states power to shut health insurers out of state health insurance exchanges starting in 2014.
