All benefits under any blanket accident and sickness policy shall be payable to the person insured, to a designated beneficiary or beneficiaries, or to their estate, except that if the person insured be a minor or otherwise not competent to give a valid release, such benefits may be made payable to their parent, guardian or other person actually supporting the insured, designated beneficiary, or beneficiaries. The policy may also provide that all or a portion of any indemnities provided by any such policy on account of hospital, nursing, medical or surgical services may with the consent of the insured 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.
