HB 1432 Washington House · 2025-2026 Regular Session

Improving access to appropriate mental health and substance use disorder services.

HB 1432 aims to improve access to mental health and substance use disorder services for individuals in Washington state. The bill updates mental health parity laws, requiring health insurance carriers to base medical necessity determinations on generally accepted standards of care and recommendations from nonprofit health care provider associations. It defines "medically necessary" to align with these standards, ensuring services address patient needs and are clinically appropriate. The legislation also expands the definition of covered mental health services over time, including prescription drugs and updated diagnostic categories for health plans issued or renewed on or after January 1, 2027.

MODERATE
This bill updates Washington's mental health parity laws to align with new federal regulations, ensuring insurance plans cover mental health services with the same standards as physical health. Key changes include stricter rules on how insurers use clinical review criteria, mandatory use of age-appropriate patient placement criteria, and tighter deadlines for responding to prior authorization requests. The bill also clarifies definitions and extends certain protections to short-term and student health plans.
Scope change
The bill now explicitly includes short-term limited duration plans and student-only health plans under the parity requirements, whereas previously these were excluded or less clearly covered.
DEFINITION

The definition of 'generally accepted standards of care' was simplified to remove a long list of specific examples, while adding a new definition for 'nonprofit professional association' to clarify which organizations can set clinical guidelines.

REQUIREMENT

Insurers must now use age-appropriate patient placement criteria from nonprofit professional associations for mental health and substance use disorder services, and they are allowed to use software tools that apply these criteria faithfully.

For utilization reviews not involving placement decisions, insurers may use clinical review criteria from either for-profit or nonprofit sources, provided they meet the standard of care requirements.

Insurers must respond to prior authorization requests within three calendar days for standard requests and one day for expedited requests, with a new requirement to approve coverage if they fail to respond on time.

The requirement for insurers to provide free nonquantitative treatment limitation parity compliance analyses was updated to specify that these must be provided within 30 days after an adverse benefit determination.

TIMELINE

The effective date for the new sections of the act was changed from January 1, 2027, to January 1, 2026, accelerating the implementation of these new rules.

ENFORCEMENT

The penalty for failing to provide requested parity compliance analyses was removed, and the section regarding civil monetary penalties for violations was deleted entirely.

TECHNICAL

The bill was renumbered from Sec. 10 and Sec. 11 to Sec. 9 and Sec. 10 respectively, and the repeal section was renumbered to Sec. 11.
