M. J. McCue and M. A. Hall, What's Behind Health Insurance Rate Increases?, The Commonwealth Fund, December 2013.
The Affordable Care Act requires health insurers to justify rate increases of 10 percent or more for nongrandfathered plans in the individual and small-group markets. Analyzing these filings for rates taking effect from mid-2012 through mid-2013, insurers attributed the great bulk—three-quarters or more—of these larger rate increases to routine factors such as trends in medical costs. Insurers attributed only a very small portion of these medical cost trends to factors related to the Affordable Care Act. The ACA-related factor mentioned most often, but only in a third of the rate filings in this study, was the requirement to cover women’s preventive and contraceptive services without patient cost-sharing. But, the insurers who point to this requirement or other ACA-related costs attributed only about 1 percentage point of their rate increases to the health reform law.
