21st Century Cures Act Interoperability & Information Blocking Deadlines [Infographic]

The 21st Century Cures Act outlines interoperability and information blocking regulations that are poised to revolutionize the healthcare industry. 

The goal of 21st Century Cures is to create a more connected healthcare system, ultimately leading to better, more informed care. 

The legislation aims to do this by putting the patient front and center. Interoperability and information blocking regulations enable patient ownership of their own EHI (electronic health information) and easier data sharing across different health systems. 

But the transformation to a more connected healthcare industry won’t happen overnight. 

Lawmakers have taken that into account, outlining key milestones as part of the 21st Century Cures Act: Final Rule

In our most recent webinar, KMS Senior Vice President of Healthcare, Patrick Gardner dove into each milestone and requirements for payers, providers, and healthcare software vendors.
