How to Choose a Rehab Center in Washington

• Verify BHSIA Licensure — Confirm active state license before enrollment at dshs.wa.gov/bhsia; unlicensed programs cannot legally bill insurance and may not meet minimum clinical standards
• Check TJC or CARF Accreditation — Joint Commission or CARF accreditation signals compliance with national quality benchmarks beyond minimum state licensing requirements
• Require a Formal ASAM Assessment — All admissions should include a six-dimensional ASAM evaluation to determine appropriate level of care; facilities that skip this step are a red flag
• Confirm MAT Availability — If opioid or alcohol use disorder is involved, verify the facility prescribes buprenorphine, naltrexone (Vivitrol), or methadone per SAMHSA guidelines
• Request a Verification of Benefits (VOB) — Ask admissions to run a VOB against your insurance before you commit; in-network facilities significantly reduce out-of-pocket cost
