Health insurance companies are smarter than your average house cat. They have reams of data about health care claims and demographics. They can forecast, with reasonable confidence, that altering some of the member cost-sharing benefits may reduce their final exposure to pay member claims. It has also been suggested that consumers who purchase health insurance off-exchange, paying the full premium rate with no subsidy, may be more judicious in how they use health care services. In other word, off-exchange consumer mays tend to file fewer health care expense claims. This results in lower rates to the consumer.
