As “Health 2.0” tools – such as healthcare apps on smartphones – become more common, it’s increasingly important for both developers and patients using these tools to learn how HIPAA protects patient medical data. Yet it is not entirely clear how HIPAA intersects with many emerging services that use digital health data. CDT launched a project to get information on what areas of HIPAA are unclear to the Health 2.0 community. If you’re a healthcare provider, Health 2.0 developer, or e-patient, and you have questions about how HIPAA affects your rights and services, please submit them to CDT. We will use these questions to urge the Office of Civil Rights (which enforces HIPAA) to provide more clarity.
