Washington is proactive in regulating regenerative treatments. Since 2018, RCW 18.130.420 has required clinics offering non-FDA approved stem cell therapies to provide clear warning signage and obtain patient consent. The state has also taken strong action against deceptive clinics⎼highlighting both promise and risk.
✅ What’s Legal in Washington?

Written Warning & Consent Requirement
Providers offering FDA-unapproved stem cell treatments must display a formal notice (11″×8.5″, 40pt type) in-office and in advertising, and obtain signed consent detailing FDA status, risks, alternatives, and benefits⎼per RCW 18.130.420. -
Autologous Stem Cell & PRP Therapies
Same-day procedures using your own cells (e.g. bone marrow, fat) and PRP treatments are permitted as part of standard medical practice under FDA minimal manipulation policies. -
