SB 897 - This act provides that health care providers shall not be required to obtain prior authorization for a health care service unless the health carrier or utilization review entity determines that in the most recent evaluation period, as defined in the act, less than 90% of the prior authorization requests submitted by that provider for that health care service were approved or would have been approved. Additionally, health care providers shall not be required to obtain prior authorization for any health care services unless the health carrier or utilization review entity has approved or would have approved less than 90% of all prior authorization requests submitted by that provider for health care services. Health carriers and utilization review entities shall notify providers within 25 days after a determination is made under the act, shall include in the notification certain information used in making the determination, shall establish an appeals process for the providers, and shall maintain an online prior authorization portal as described in the act. No health carrier or utilization review entity shall deny or reduce payment to a health care provider for a health care service for which the provider has prior authorization, except as described in the act. This act shall not apply to MO HealthNet services not provided through a managed care organization, or to providers who have not participated in a health benefit plan offered by the health carrier for at least one full evaluation period. This act is substantially similar to HB 618 (2025) and to provisions in HCS/SB 94 (2025), and is similar to SB 230 (2025), SB 983 (2024), HB 1976 (2024), SB 576 (2023), and HB 1045 (2023).
