New Washington Law Has Broad Implications For Protecting Consumer Health Data

On April 27, 2023, Washington Governor Jay Inslee signed into law the My Health My Data Act (the "Act"), which will regulate the collection, use, and disclosure of "consumer health data" ("Consumer Health Data" or "CHD"). The Act is intended to provide stronger privacy and security protections for health-related information not protected under the Health Insurance Portability and Accountability Act of 1996 ("HIPAA"), but a significant gap remains. In spite of its title and purported focus on the health information of Washington residents, a careful reading of the Act shows that it will have a much broader reach – both geographically and substantively. Most provisions of the Act come into effect on March 31, 2024, with small businesses required to comply by June 30, 2024. Some sections (e.g., Section 10 prohibition against "geofencing") do not provide effective dates. It is unclear whether those sections become effective on July 22, 2023, which would be 90 days after the end of the legislative session, as provided under Washington law, or whether failure to include an effective date for all sections of the Act was an oversight.

Whom the Act Covers

The Act applies to entities that conduct business in Washington, or that "produce" or "provide" products or services that are targeted to consumers in Washington, and that determine the purpose and means of collecting or using CHD ("regulated entities"). This includes "small businesses," which are regulated entities that: (a) collect, process, sell, or share the consumer health data of fewer than 100,000 consumers in a calendar year; or (b) derive less than 50% of gross revenue from collecting, processing, selling, or sharing CHD, and control, process, sell, or share the CHD of fewer than 25,000 consumers. Unlike other state privacy laws, the Act does not exempt these smaller businesses but merely postpones by three months the date by which small businesses must come into compliance.

Also unlike other state privacy laws that protect that state's residents, the Act defines "consumers" broadly to include not just Washington residents but also any natural person whose CHD is "collected" in Washington. And because the Act defines "collect" to mean "buy, rent, access, retain, receive, acquire, infer, derive, or otherwise process consumer health data in any manner," any regulated entity located anywhere – including outside of the U.S. – that retains or processes CHD in Washington, or that contracts with a "processor" (as defined in the Act, and including a cloud or other service provider) that retains, processes (e.g., stores) or allows access to CHD in Washington, will be subject to the Act with respect to the CHD of any natural person, regardless of where that natural person resides.

What Data the Act Covers

"Consumer health data" is broadly defined as personal information[1] that is linked or reasonably linkable to a consumer and that identifies the consumer's past, present, or future physical or mental health status. The Act includes a long, non-exhaustive list of data elements that comprise CHD (CHD "includes, but is not limited to" the elements listed) and covers some information that is not typically thought of as health-related. The list of CHD includes the following:

While some of these data elements describe information that typically is associated with health-related conditions or treatment, some go far beyond that. For instance, the definition of CHD could capture grocery items purchased that might indicate someone is diabetic. Or it could be broadly interpreted to encompass a consumer's online browsing history showing a search for information about yoga studios or other wellness activities. An open question is when precise location information would reasonably indicate that a consumer has attempted to acquire – or has acquired – health care services or supplies. For example, it is not clear whether precise location information showing that someone went to a hospital is CHD because someone could visit a hospital for treatment or to visit a friend or family.

Most important, because "consumers" include any natural person whose CHD is "collected" (e.g., "retained" or "processed") in Washington, this could include the CHD of, for example, a New York resident whose search request is initially collected and analyzed by a company in California but later stored on or accessed from a server in Washington—including by a cloud services provider that hosts some of its customers' data in Washington.

The Act does not apply to such data in an employment (e.g., HR-related records) or commercial (i.e., B2B) context. De-identified data and publicly available data are excluded from the definition of "personal information" and therefore are not CHD. The Act includes a long list of other exemptions:
