State lawmakers voted to let companies from elsewhere sell insurance here, a move that could cut premiums but leave many Arizonans without coverage for some medical conditions. SB 1593 eliminates laws requiring insurers that sell their products to Arizona residents be licensed and regulated by the state Department of Insurance. Proponents say the increased competition will provide more opportunities for Arizonans to get the coverage they want at a price they can afford. But the flip side is that the legislation wipes out more than two-dozen mandates for what conditions must be covered for policies issued in Arizona.
