The bill amends the "Benefit Determination and Utilization Review Act" by adding a new section, 27-18.9-16, which establishes a presumption of medical necessity for healthcare services or procedures authorized by a provider. Specifically, it states that any healthcare service or procedure authorized by a provider to a patient shall create a presumption that the service or procedure is medically necessary. Consequently, it is the duty of the insurance company to provide justification for any denial of such healthcare service or procedure. The act is set to take effect immediately upon passage.
