Preferred provider arrangements may include capitated payments that are limited to the health services provided by the provider.

Preferred provider arrangements may embody risk transfer between carriers and providers in accordance with the provisions of chapter 56-A, subchapter III. Any other acceptance of insurance risk by a person that does not hold a valid certificate of authority or license and is not exempt by law from licensure constitutes the unauthorized transaction of insurance within the meaning of section 404 and chapter 21.
