Any group health policy may provide that all or any portion of any indemnities provided by any such policy on account of hospital, nursing, medical or surgical services may, at the insurer’s option, be paid directly to the hospital or person rendering such services, but the policy may not require that the service be rendered by a particular hospital or person. Payments so made shall discharge the insurer’s obligation with respect to the amount of insurance so paid.
