Iowa Code section 505.19 requires the Commissioner to hold a public hearing on a proposed health insurance rate increase which exceeds the average annual health spending growth rate as published by the Centers for Medicare and Medicaid Services of the United State Department of Health and Human Services

In 2014, none of the filed rates showed increases at such a rate that would trigger this requirement.  Significantly, 2014 was the first year of the Affordable Care Act, and thus there was no baseline for the rate increases to be compared against.
