5307.2. The administrative director shall contract with an independent consulting firm, to the extent permitted by state law, to perform an annual study of access to medical treatment for injured workers. The study shall analyze whether there is adequate access to quality health care and products, including prescription drugs and pharmacy services, for injured workers and make recommendations to ensure continued access. If the administrative director determines, based on this study, that there is insufficient access to quality health care or products for injured workers, including access to prescription drugs and pharmacy services, the administrative director may make appropriate adjustments to medical, prescription drugs and pharmacy services, and facilities' fees. When there has been a determination that substantial access problems exist, the administrative director may, in accordance with the notification and hearing requirements of Section 5307.1, adopt fees in excess of 120 percent of the applicable Medicare payment system fee, or in excess of 100 percent of the fees prescribed in the relevant Medi-Cal payment system, for the applicable services or products.
