RCW 74.09.655

The authority shall provide coverage under this chapter for smoking cessation counseling services, as well as prescription and nonprescription agents when used to promote smoking cessation, so long as such agents otherwise meet the definition of "covered outpatient drug" in 42 U.S.C. Sec. 1396r-8(k). However, the authority may initiate an individualized inquiry and determine and implement by rule appropriate coverage limitations as may be required to encourage the use of effective, evidence-based services and prescription and nonprescription agents.
