From the HHS Office for Civil Rights website: Ask your doctor. You have the right to see and get copies of your health information - PDF. In most cases, you can get a copy the way you want it, such as by e-mail. While your doctor normally has up to 30 days to provide you a copy of your information, your doctor often can provide the information much sooner than that. If your doctor offers a web portal, you may be able to easily view and download your health information whenever you want.
This 2-page ONC published graphic novel (aka comic book) is a short guide that helps illustrate why protecting your health privacy is important and issues to consider when sharing sensitive health information.
