On September 9, 2013, California Governor Jerry Brown signed Assembly Bill 658 into law. The bill amends California’s Confidentiality of Medical Information Act, which requires healthcare providers obtain consent before using, sharing or selling patient medical information. The bill expands the definition of “provider of health care” to include medical records providers and “[a]ny business that offers software or hardware to consumers, including a mobile application or other related device that is designed to maintain medical information.” The new law takes effect January 1, 2014.
