The bill aims to revise preauthorization laws by directing the Department of Public Health and Human Services to eliminate the requirement for prior authorization for certain antipsychotic drugs. Specifically, the department is prohibited from requiring prior authorization under the Medicaid program for any antipsychotic drug that has been approved by the U.S. Food and Drug Administration for its approved indications for Medicaid members aged 18 years and older. This change is intended to facilitate timely treatment for individuals with serious mental illnesses.

Additionally, the bill clarifies that the department is not obligated to cover antipsychotic drugs that do not meet the eligibility criteria outlined in federal law (42 U.S.C. 1396r-8). The act will take effect 30 days after it is passed and approved, and it will apply to claims submitted for payment for services provided on or after the effective date.
