The allegation in this article that the new federal Genetic Non-Discrimination Act, which restricts access to the insured's genetic data - and thereby hinders their ability to set premiums - seems like another bogus ploy by the insurance industry to discredit this legislation.  Insurers contend that the new legislation will therefore increase insurance costs. 

Compared to what?  The insurance industry probably only ever had limited genetic data, over a short period, likely with limited (accurate) long term predictive power - so their ability to set insurance rates is likely the same now as it always was.  The insurance industry looks for every edge they can get whether it is valid or not to tilt the underwriting equation in their favour and this is just another obvious example.
