DES MOINES, Iowa (AP) — An Iowa law approved this spring in the Republican-controlled Legislature would allow the conservative and politically powerful Iowa Farm Bureau to offer health plans that skirt requirements of the Affordable Care Act. But several months after a ceremonial bill signing, few details are available about how the plans will work for people with rising health insurance costs. It represents another attempt by GOP-controlled states to chip away at some of the federal rules imposed under the 2010 law championed by former President Barack Obama.

National health care experts have reacted skeptically, arguing it could be a moneymaker for the Farm Bureau but won’t help people most in need. An official for insurer Wellmark Blue Cross and Blue Shield, which is helping run the plans, denies that they’ll provide skimpy coverage.
