Washington’s new data privacy statute, “My Health, My Data Act” (“MHMD” or the “Act”), officially became fully effective on March 31, 2024, for regulated entities under the Act, while small businesses have until June 30, 2024, to comply. The purpose of MHMD is to protect consumers’ personal health data not otherwise protected by federal regulation, such as HIPAA. Businesses should be familiar with Washington’s preexisting biometric privacy law, RCW 19.375, and recognize MHMD’s coverage is far more expansive. MHMD regulates the collection, sharing, selling, and processing of “consumer health data.” It applies to entities that conduct business in Washington as well as those that provide services or products to Washington.
