Any such health maintenance organization whose contract with medicare is being terminated shall give each resident of the commonwealth who is covered under a medicare program offered by such health maintenance organization and each nonprofit hospital service corporation and medical service corporation in the commonwealth sixty days notice prior to such termination. Any such health maintenance organization shall cooperate fully in the prompt transfer of coverage to any organization which will assume such coverage.
