Kaiser Permanente is non-profit HMO carrier that offers medical and vision coverage in California. Kaiser is unique among California carriers in that it both provides health insurance coverage and medical services through its own network of doctors and hospitals. Kaiser allows any numbers of plans to be offered, and can also be offered in conjunction with plans from another carrier to give employees choice of Kaiser and non-Kaiser options.
Kaiser primarily offers HMO plans, and Kaiser insurance can only be used at Kaiser medical facilities. Out of state employees have the option of enrolling on a PPO plan with access to the Private Healthcare Systems network. Kaiser plans are also available through the Covered California SHOP exchange.
Kaiser serves most areas of California, but has limited networks in certain parts of California given the size of its doctor network. Kaiser plans tend to be the most cost effective plans in most parts of California.
