One of the state's largest health care insurers has reached a $25 million agreement with regulators. The effort is to right the wrong of dropping coverage for nearly a thousand patients when they tried to make use of their policies. Woodland Hills-based Health Net has agreed to offer new coverage to 926 customers who have been dropped from individual or family policies since 2004. The company pledges to repay up to $14.2 million in outstanding medical expenses and waive up to $7.2 million in insurance premiums in a settlement with the California Department of Insurance.
