Insurers want to change President Barack Obama's health care law to provide financial assistance for people buying bare-bones coverage. That would entice the healthy and the young, the industry says, holding down premiums. So-called catastrophic plans are currently not eligible for the law's subsidies, and only 2 percent of the 8 million consumers who signed up this year picked one. Subsidies bring down the cost of monthly premiums. The proposed change is part of a package of recommendations that America's Health Insurance Plans, the main industry trade group, plans to release Wednesday.
