Legislation that will require insurance companies to offer coverage for autism treatments has been signed into Michigan law.
Lt. Gov. Brian Calley signed the measures Wednesday. Gov. Rick Snyder is in Afghanistan.
Lawmakers gave final legislative approval to the measures last month.
Snyder supported the legislation that was championed in part by Calley, who has a daughter with autism.
Previous efforts to mandate insurance coverage for autism had failed in Michigan. But a bill backed by Senate Majority Leader Randy Richardville helped soften opposition by setting up a fund to help reimburse some companies for paid claims related to diagnosis and treatment of autism.
A majority of states already have laws aimed at requiring insurance companies to cover some types of autism therapies.
