     AN ACT Relating to mental health parity; amending RCW 48.21.240, 48.44.340, and 48.46.290; adding new sections to chapter 41.05 RCW; adding a new section to chapter 48.21 RCW; adding a new section to chapter 48.44 RCW; adding a new section to chapter 48.46 RCW; adding new sections to chapter 70.47 RCW; adding a new section to chapter 48.02 RCW; creating a new section; and declaring an emergency.

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF WASHINGTON:

NEW SECTION.  Sec. 1   The legislature finds that the costs of leaving mental disorders untreated or undertreated are significant, and often include: Decreased job productivity, loss of employment, increased disability costs, deteriorating school performance, increased use of other health services, treatment delays leading to more costly treatments, suicide, family breakdown and impoverishment, and institutionalization, whether in hospitals, juvenile detention, jails, or prisons.
     Treatable mental disorders are prevalent and often have a high impact on health and productive life. The legislature finds that the potential benefits of improved access to mental health services are significant. Additionally, the legislature declares that it is not cost-effective to treat persons with mental disorders differently than persons with medical and surgical disorders.
     Therefore, the legislature intends to require that insurance coverage be at parity for mental health services, which means this coverage be delivered under the same terms and conditions as medical and surgical services.

NEW SECTION.  Sec. 2   A new section is added to chapter 41.05 RCW to read as follows:
     (1) For the purposes of this section, "mental health services" means medically necessary outpatient and inpatient services provided to treat mental disorders covered by the diagnostic categories listed in the most current version of the diagnostic and statistical manual of mental disorders, published by the American psychiatric association, on the effective date of this section, or such subsequent date as may be provided by the administrator by rule, consistent with the purposes of this act, with the exception of the following categories, codes, and services: (a) Substance related disorders; (b) life transition problems, currently referred to as "V" codes, and diagnostic codes 302 through 302.9 as found in the diagnostic and statistical manual of mental disorders, 4th edition, published by the American psychiatric association; (c) skilled nursing facility services, home health care, residential treatment, and custodial care; and (d) court ordered treatment unless the authority's or contracted insuring entity's medical director determines the treatment to be medically necessary.

Wellness and preventive services that are provided or reimbursed at a lesser copayment, coinsurance, or other cost sharing than other medical and surgical services are excluded from this comparison; and
     (ii) Prescription drugs intended to treat any of the disorders covered in subsection (1) of this section to the same extent, and under the same terms and conditions, as other prescription drugs covered by the health benefit plan.
