If a pharmacy, operated by or contracted with by a health maintenance organization, is closed or is unable to provide health care services to an enrollee in an emergency, a pharmacist may take an assignment of such enrollee’s right to reimbursement, if the policy or contract provides for such reimbursement, for those goods or services provided to an enrollee of a health maintenance organization. No health maintenance organization shall refuse to pay the pharmacist any payment due the enrollee under the terms of the policy or contract.
