You may be given a "heads up" soon if your health care costs are going to increase by at least seven percent. Oregon Senators just approved a bill that would require health insurers in Oregon to warn policyholders of impending rate increases. Under the measure, an insurer that files for a rate increase of 7% or more that affects at least 1000 people must alert those customers. The bill would apply to insurance companies selling coverage to individuals and small businesses. The measure now goes to the House for debate.
