My Health My Data Act Overview (WA)

Summary

This practice note explains the fundamentals of Washington State's recently enacted My Health My Data Act, Wash. Rev. Code Ann. §§ 19.373.005–19.373.900 (MHMD or Act), which aims to protect ''consumer health data.'' The Act, which takes full effect on March 31, 2024, for most regulated entities, applies to companies that collect and process consumer health data and conduct business in Washington or provide products or services that are targeted to consumers in Washington. It also applies to processors that collect and handle consumer health data on behalf of regulated entities. Because of its potentially broad scope and private right of action, MHMD is expected to have national implications and may be one of the most significant U.S. privacy laws enacted in recent years.
