This bill amends existing law (RCW 74.09.520) and changes what "medical assistance" includes, adds new coverage requirements, and imposes various procedural and payment rules. It specifies a list of services that medical assistance may include, expressly prohibits terminating prescription medications, oxygen, respiratory services, or other life‑sustaining medical services or supplies, and excludes routine foot care and non‑Title XIX mandated dental services unless specifically appropriated. It also adds definitions for "durable medical equipment" and "seizure detection device." The amendment requires the department to adopt rules so Title XIX personal care services conform to federal rules, including financial eligibility, assessment of functional disability, nurse review of plans of care, and prioritization based on assessed need and available funds. It authorizes contracting for case management and reassessment with area agencies on aging or federally recognized tribes, allows competitive bidding or direct provision if contractors are unavailable, and permits, subject to appropriation, Medicare Part D copayment coverage for full benefit dual eligibles. The bill mandates specific coverage and payment changes with deadlines: universal autism/developmental delay screening (effective Jan. 1, 2016, subject to funds), youth and maternal depression screening payments (effective Jan. 1, 2018, subject to appropriation), coverage for USPSTF A/B rated noninvasive colorectal cancer screening and follow‑up colonoscopies (effective Jan. 1, 2024), payment rules for hospitals when discharge placement is unavailable, and, effective Jan. 1, 2026, full coverage of FDA‑approved seizure detection devices and related services/subscriptions as durable medical equipment with subscription reimbursement set at 100% of the authority's telemonitoring monthly rate and a biennial review requirement of covered devices. The text references other statutes and programs but does not identify the specific agency names for "authority" or "department," does not state the numeric telemonitoring rate, and omits detailed rulemaking, funding, and implementation procedures.

If enacted, Medicaid enrollees with seizure disorders would likely gain access to fully covered seizure detection devices and the required ongoing subscriptions, which would increase Medicaid spending on durable medical equipment and monitoring services and shift costs that families or caregivers might otherwise bear to the state program. Hospitals would be more likely to receive payment for patients who are medically ready for discharge but have no available long‑term placement, reducing hospital uncompensated days and creating a clearer revenue path when nursing home or other placements are unavailable; managed care plans will face new administrative and review responsibilities tied to those payments. Area agencies on aging and federally recognized tribes would have clearer opportunities and responsibilities to provide case management and reassessments for in‑home personal care services, while the state authority and department must adopt rules and assessment systems to align personal care services with federal requirements and prioritize those with greatest need; however, many costs and timing depend on future appropriations, the exact agencies referenced are not named here, and the specific reimbursement rate for remote monitoring subscriptions is not provided, leaving some implementation details and budget impacts uncertain.
