This section applies to grandfathered health plans. “Grandfathered health plan” has the meaning stated in the Patient Protection and Affordable Care Act [Pub. L. 111-148], as amended by the Health Care and Education Reconciliation Act of 2010 [Pub. L. 111-152]. Every insurance company, nonprofit health service corporation, and health maintenance organization that offers an accident and health line of insurance shall establish and implement an independent external review mechanism to review and determine whether medical care rendered under the line of insurance was medically necessary and appropriate to the claim as submitted by the provider. For purposes of this section, “independent external review” means a review conducted by the North Dakota health care review, inc., another peer review organization meeting the requirements of section 1152 of the Social Security Act, or any person designated by the commissioner to conduct an independent external review. A determination made by the independent external reviewer is binding on the parties. Costs associated with the independent external review are the responsibility of the nonprevailing party. A provider may not use an independent external review under this section unless the provider first has exhausted all internal appeal processes offered by the insurance company, nonprofit health service corporation, or health maintenance organization. The insurance commissioner shall take steps necessary to ensure compliance with this section. If federal laws or rules relating to independent external review are amended, repealed, or otherwise changed, the insurance commissioner shall adopt rules to ensure the independent external review procedure is in compliance with and substantively equivalent to the federal requirements.
