Are Gender Ratings Illegal Under the ACA?

To be clear does. . . “Women will no longer be charged more for their insurance coverage just for being women. Under a practice known as “gender rating,” insurers currently charge women higher premiums than men for identical health benefits. As a result, women now pay $1 billion more than men each year for the same health plans in the individual market. As of 2014, however, under the Affordable Care Act, gender rating will become illegal in all new individual and small group plans.” . . .mean that if the premiums for a female are more than those for a male (in the same age range) that is illegal? Example, with an employer provided plan, the premiums for a female age 35-39 is $65.20, but for a male 35-39 it is $38.24. . .
