Golden State insurance regulators are giving the public a look at insurers’ explanations about why health coverage prices are going up.

The California Department of Insurance has posted individual health insurance rate filings on the Web.

The carriers included are Aetna Inc., Hartford (NYSE:AET); Blue Shield of California, San Francisco; and the Anthem Blue Cross unit of WellPoint Inc., Indianapolis (NYSE:WLP).

California Blue has asked for an average increase of 18% for 240,000 policyholders.

Anthem has asked for a 14% increase for 700,000 policyholders, and Aetna has asked for a 19% increase for 65,000 policyholders.

California does not require prior approval of health insurance rates, but it does require individual health insurers to spend 70% of premium revenue on medical benefits, officials say.
