Before a health insurer selling an individual policy or group health benefit plan, as defined in ORS 743B.005, may cancel a policy for nonpayment of premium, the insurer must mail a separate notice to the policyholder at least 10 days prior to the end of the grace period informing the policyholder that the premium was not received and that the policy will be terminated as of the premium due date if the premium is not received by the end of the applicable grace period required by ORS 743.417 and 743B.320. The notice shall be in writing and mailed by first class mail to the last-known address of the policyholder.
