Does Community Health Plan of Washington (CHPW) Cover Addiction Treatment?

Community Health Plan of Washington (CHPW) is a not-for-profit health insurance provider based in the state of Washington. Established in 1992, CHPW offers comprehensive health coverage tailored primarily for Washington's Medicaid and Medicare beneficiaries. The provider prides itself on delivering cost-effective healthcare solutions while partnering with local communities to advance public health. CHPW operates independently, with no direct parent company but works closely under the umbrella of Washington's Health Care Authority. They focus extensively on providing personalized care through an extensive network of hospitals, doctors, and specialists ensuring the best possible outcomes for their members.

Two federal laws make coverage for substance use disorder treatment close to universal in the United States. The Affordable Care Act lists mental health and substance use disorder services among the ten essential health benefits that individual and small-group plans must include. The Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) goes further: when a plan covers behavioral health, it may not impose financial requirements or treatment limitations more restrictive than those applied to comparable medical and surgical care.

What differs from member to member is not usually whether treatment is covered but how much you pay and what approval is required — and both come down to your specific plan, network status and deductible. The fastest way to find out is a benefits check, which takes a few minutes and costs nothing.
