Oregon Revised Statutes Insurance § 743.543

All benefits under a blanket health insurance policy shall be payable to the person insured, or to the designated beneficiary or beneficiaries of the person, or to the estate of the person, except that if the person insured is a minor or otherwise not competent to give a valid release, such benefits may be made payable to the parent, guardian or other person actually supporting the person. However, the policy may provide that all or a portion of any indemnities provided by such policy on account of hospital, nursing, medical or surgical services may, at the option of the insurer and unless the insured requests otherwise in writing not later than the time of filing proofs of such loss, be paid directly to the hospital or person rendering such services; but the policy may not require that the services be rendered by a particular hospital or person. Payment so made shall discharge the obligation of the insurer with respect to the amount of insurance so paid.
