Nothing in this Section shall require the insurer to cover a treatment when the authorization was granted based on a material misrepresentation by the insured, the policyholder, or the provider. Nothing in this Section shall require Medicaid managed care organizations to pay for services if the individual was not eligible for Medicaid at the time the service was rendered.

Pursuant to subsection (b), in conducting utilization review of all covered services and benefits for the diagnosis, prevention, and treatment of substance use disorders an insurer shall use the most recent edition of the patient placement criteria established by the American Society of Addiction Medicine.
     (m) For medical necessity determinations relating to level of care placement, continued stay, and transfer or discharge that are within the scope of the sources specified in subsection (l), an insurer shall not apply different, additional, conflicting, or more restrictive utilization review criteria than the criteria set forth in those sources. For all level of care placement decisions, the insurer shall authorize placement at the level of care consistent with the assessment of the insured using the relevant patient placement criteria as specified in subsection (l). If that level of placement is not available, the insurer shall authorize the next higher level of care. In the event of disagreement, the insurer shall provide full detail of its assessment using the relevant criteria as specified in subsection (l) to the provider of the service and the patient.
     Nothing in this subsection or subsection (l) prohibits an insurer from applying utilization review criteria that were developed in accordance with subsection (k) to health care services and benefits for mental, emotional, and nervous disorders or conditions that are not related to medical necessity determinations for level of care placement, continued stay, and transfer or discharge. If an insurer purchases or licenses utilization review criteria pursuant to this subsection, the insurer shall verify and document before use that the criteria were developed in accordance with subsection (k).
     (n) In conducting utilization review that is outside the scope of the criteria as specified in subsection (l) or relates to the advancements in technology or in the types or levels of care that are not addressed in the most recent versions of the sources specified in subsection (l), an insurer shall conduct utilization review in accordance with subsection (k).
     (o) This Section does not in any way limit the rights of a patient under the Medical Patient Rights Act.
