Sutter Health, a large network of doctors and hospitals in Northern California that has long been accused of abusing its market power, is now squaring off against major U.S. corporations in a closely watched legal fight.

The battle is over Sutter's demand that companies sign an arbitration agreement to resolve any legal disputes with the health system.

California's dental health system for the poor is dysfunctional, according to a report by a bipartisan oversight commission.

Amid growing questions over the future of Obamacare exchanges, the head of California's marketplace said the nation's largest private health insurer should take responsibility for nearly $1 billion in losses and stop blaming the federal health law.

Private health plans invoiced the state of California $387.5 million to cover high-cost hepatitis C treatments in Medi-Cal between July 2014 and November 2015, when just 3,624 patients received the treatments, according to the California Department of Health Care Services.
