An Act relating to medical assistance services; relating to parity in mental health and substance use disorder coverage in the state medical assistance program; and providing for an effective date.

SB 45 requires Alaska's state medical assistance program (Medicaid) to comply with federal mental health and substance use disorder parity laws. It mandates the health department to review all complaints about coverage disparities, examine how treatment limitations (like prior authorization or step therapy) are applied, and compare these practices between mental health/substance use benefits and medical/surgical benefits. The bill also requires an annual report to the legislature by March 1st, detailing processes for determining medical necessity, identifying any stricter limitations for mental health care, and confirming compliance with federal parity standards. This directly affects Medicaid enrollees and providers by ensuring mental health and substance use disorder coverage is treated equally to physical health coverage under the state program.
