Effective July 1, Florida Will Prohibit Offshore Storage of Health Records and Require Additional Ownership Disclosures
June 20, 2023 | Blog | By Kate Stewart, Cassandra Paolillo
A new Florida law will require certain Florida-licensed providers to ensure that patient information is physically maintained only in the continental United States and its territories or in Canada. Florida SB 264, which goes into effect July 1, 2023, amends the Florida Electronic Health Records Exchange Act, adding a ban on offshoring health information that goes beyond the requirements under HIPAA and most other generally applicable health privacy and security laws. Florida licensees to which the new requirements apply will need to attest upon initial licensure and any renewals that they are in compliance with the new requirements. Applicable licensees will also be required to ensure that no individual or entity with a controlling interest in the licensee has an interest in an entity that has a business relationship with certain foreign countries.
OCR Proposes HIPAA Amendments to Protect Reproductive Health Care Information
April 13, 2023 | Blog | By Dianne Bourque, Kate Stewart, Pat Ouellette
In response to concerns about the confidentiality of protected health information (PHI) related to reproductive health care less than one year after Dobbs v. Jackson Women’s Health Organization decision, and the prospect of such PHI being weaponized by states and used against patients, the U.S. Department of Health & Human Services Office for Civil Rights (OCR) has proposed amendments to the HIPAA Privacy Rule to protect that information.
Is Your Website Collecting PHI Under OCR's New Tracking Technologies Bulletin?
December 7, 2022 | Blog | By Dianne Bourque, Lara Compton, Kathryn Edgerton, Cassandra Paolillo, Kate Stewart
Covered Entities and Business Associates should promptly and carefully review their use of online tracking technologies on their websites and mobile apps following a bulletin (Bulletin) published by the U.S. Department of Health and Human Services’ Office for Civil Rights (OCR) last week. The Bulletin addresses multiple facets of compliance with HIPAA when using online third-party tracking technologies (Tracking Technologies). In doing so, OCR significantly expands its interpretation of the definition of Protected Health Information (PHI) to include, in some instances, identifiable information gathered by Tracking Technologies where a user visits a website and does not interact with the entity in any other way. In its Bulletin, OCR interprets the act of an individual visiting a website as evidence of a relationship or anticipated future relationship between the visitor and the entity.
What Would the American Data Privacy and Protection Act Mean for the Health Industry?
June 23, 2022 | Blog | By Kate Stewart, Pat Ouellette
All players in the health and wellness ecosystem should be following developments around the American Data Privacy and Protection Act (ADPPA). If enacted, the ADPPA would be a watershed in the regulation of the privacy and security of personal information, including health information. The ADPPA would have a particularly large impact on entities that currently collect, process, and transmit health information but are not subject to HIPAA.
