Engrossed Substitute House Bill 1689 as Recommended by Health Care & Wellness - as passed by the Legislature


Section 1

This section adds a new section to an existing chapter 48.43. Here is the modified chapter for context.

    1. Stage 3 or 4 cancer; or

    2. Recurrent, relapsed, refractory, or metastatic cancer.

  2. For purposes of this section, "biomarker test" means a single or multigene diagnostic test of the cancer patient's biospecimen, such as tissue, blood, or other bodily fluids, for DNA, RNA, or protein alterations, including phenotypic characteristics of a malignancy, to identify an individual with a subtype of cancer, in order to guide patient treatment.

  3. For purposes of this section, biomarker testing must be:

    1. Recommended in the latest version of nationally recognized guidelines or biomarker compendia, such as those published by the national comprehensive cancer network;

    3. A covered service; and

    4. Prescribed by an in-network provider.

  4. This section does not limit, prohibit, or modify an enrollee's rights to biomarker testing as part of an approved clinical trial under chapter 69.77 RCW.

  5. Nothing in this section may be construed to mandate coverage of a health care service.

  6. Nothing in this section prohibits a health plan from requiring a biomarker test prior to approving a drug or treatment.
