"Senate Republican leaders on [July 13] unveiled a fresh proposal to repeal and replace the [ACA] ... [T]he bill would allow insurers, under certain conditions, to offer health plans that did not comply with standards in the [ACA].... If an insurer offered 'sufficient minimum coverage' on the exchange that remains subject to federal mandates in the [ACA], it could also offer coverage outside the exchange that would be exempt from many of those mandates.... Policies that comply with the [ACA] would provide more extensive coverage but would also attract sicker people with higher medical costs. To address this concern, the Republican bill would create a fund to make payments to insurers for the costs of covering high-risk people enrolled in health plans on the exchanges."
