A Nevada state report says many insurers put more hurdles in front of mental health care than physical care, likely breaking federal parity rules. The Nevada Division of Insurance posted a compliance report that names 16 carriers. The report says some plans demand prior approval that members cannot find in plan documents. It also says they deny more mental health claims, pay less for treatment, and use weaker provider credentialing. Regulators say enforcement takes time and may lead to exams and fines. The Nevada Association of Health Plans represents 10 companies. They said they are reviewing the report and welcome the opportunity to better understand and address concerns.
