A health insurance policy may pass by transfer, will, or succession to any person, whether that person has an insurable interest or not, and that person may recover any benefit payable under the policy in accordance with the terms of the policy, but in no event shall such transfer or succession operate to change the named insured or insureds covered under the policy. An insured under a group health insurance policy, pursuant to agreement among the insured, the group policyholder and the insurer, may make an assignment of all or any part of the incidents of ownership held by the insured under the policy, including any right to designate a beneficiary and any right to have an individual policy issued in case of termination of employment. An assignment, whether made prior to or subsequent to July 1, 1971, is valid for the purpose of vesting in the assignee all the incidents of ownership assigned, and entitles the insurer to deal with the assignee as the owner in accordance with the policy, but without prejudice to the insurer on account of any payment made or individual policy issued prior to receipt by the insurer of such notice as may be required by the policy.
