My Health My Data- Washington’s Health Data Privacy Revolution

| 17 min

On April 27, 2023, Washington Governor Jay Inslee signed into law the My Health My Data Act (MHMD). The law has an effective date of July 23, 2023, but the deadline to comply with most of its requirements is March 31, 2024.* While the 2023 state legislative season may see the addition of four comprehensive privacy laws (Iowa, Indiana, Montana, and Tennessee), My Health My Data (HB 1155) could have the most far-reaching impact on businesses.
