A consumer advocacy group says Louisiana will be among nine states where federal review of health insurance rates will improve upon the current system, where rates are not regulated.

Beginning Thursday, the U.S. Department of Health and Human Services will review health insurance rates in Louisiana; Alabama; Arizona; Idaho; Missouri; Montana; Pennsylvania; Virginia and Wyoming.

Health insurers must publicly justify the reasons for any rate increase of 10 percent or more and consumers in the states where rates are under review should expect to see significant improvement, according to Consumer Watchdog.

However, the new rules will not prevent unreasonable premium increases because they do not give insurance regulators the authority to reject increases that cannot be justified, according to Consumer Watchdog.
