Engrossed Substitute House Bill 2242 amends multiple statutes (including RCW 48.43.047 and RCW 70.290.010), adds new sections to chapter 43.70 RCW and chapter 44.28 RCW, creates other new sections, and declares an emergency with an expiration provision (the specific expiration date and full emergency language are not provided in the extracted text). The bill states the legislative intent to preserve access to evidence‑based preventive health services while not requiring any individual to receive immunizations or changing informed consent laws. The bill gives the Department of Health authority to issue immunization recommendations and related guidance (which must be posted on its website) and explicitly exempts that guidance from the rule‑making requirements of chapter 34.05 RCW. Nongrandfathered health plans issued on or after April 1, 2026 must, at minimum, cover specified preventive services identified by federal and HRSA guidelines in effect on June 30, 2025 and immunizations recommended by the Department of Health under the new section. Coverage must follow federal rules and department guidance, apply to plan years beginning one year after the recommendation or guideline is issued, and generally prohibit in‑network cost‑sharing for those services; limited cost‑sharing is permitted for Health Savings Account–qualified plans. Carriers may use reasonable medical management where recommendations/guidelines do not specify details, and the Insurance Commissioner may adopt implementing rules after consulting other agencies and experts. The bill also establishes procedures to fund state vaccine purchases through assessments administered by the Washington vaccine association and requires the Department of Health secretary to estimate the nonfederal program cost annually and prioritize federal discount purchasing. Licensed health carriers, third‑party administrators, state and local governments, and school districts are subject to assessments based on attributed vaccine usage for covered lives under age 19, with an attribution mechanism that must record date of service, patient name, vaccine received, and plan eligibility and comply with health information privacy laws. The act includes timeline provisions (some referencing historical implementation dates), a mandate for a JLARC postenactment review to be informed by data submitted by the Department of Health and the Office of the Insurance Commissioner (data due September 30, 2031; review due November 15, 2032), and a severability provision. The extracted material omits or cuts off several specifics: a portion of a key definition beginning “Total nonfederal pr...,” the full text of the amendment to RCW 70.290.040, the full new section added to chapter 44.28 RCW, the detailed emergency and expiration language, and any other sections of the bill not included in the provided excerpts. No criminal penalties or new crimes are described in the extracted facts; the changes are regulatory, funding, and coverage procedure changes.

If enacted, health insurers and third‑party administrators will face a new, ongoing funding obligation to help the state buy vaccines for people under 19 who are not covered by federal vaccine programs or state‑purchased children’s plans. An appointed association board will set how much each carrier or TPA pays using an attribution method that relies on providers’ vaccine administration records (including date of service, patient name, vaccine, and plan eligibility), so carriers must provide and manage that data under existing privacy laws. The association can require prepayments, cover shortfalls and then bill members, and annual cost estimates and assessments are set by the Department of Health on a recurring schedule, which likely raises carriers’ administrative work and costs and could be passed on to employers or enrollees. The Department of Health will also publish immunization recommendations that nongrandfathered plans issued on or after April 1, 2026 must cover without in‑network cost‑sharing (and without cost‑sharing from an out‑of‑network provider when no in‑network provider is available), with a narrow exception for HSA‑qualified plans. The Insurance Commissioner can write implementing rules, and a legislative audit of the program is scheduled for 2032 with agency data due in 2031. Key details are missing from the provided text — for example the full definition of the state’s nonfederal program cost, the specific vaccines covered under the new DOH recommendations, the exact expiration date and some amendments referenced elsewhere — so the precise size of assessments and the full fiscal impact on carriers, governments, and enrollees is uncertain.
