Information blocking
and sharing

Patient with nurse

The rules are changing

We all want to avoid Information blocking—the act of unreasonably interfering with or preventing the interoperability of Electronic Health Information (EHI) through actions, inaction, cumbersome processes, or excessive fees.

On October 6, 2022, the scope of EHI under federal rules increased substantially. The expanded definition includes any electronic Protected Health Information (ePHI) under HIPAA that could be contained in a patient medical or billing record, or could be used to make a decision about a patient.

What should you do?

Be sure to understand:

  • What EHI you have
  • Where is your EHI located in your various healthcare IT products
  • If and how you can make that EHI available if requested

There are no specific electronic formats or methods of sharing explicitly required, but you should continue to prioritize work to ensure interoperability and information sharing. To do so, you should also adopt new releases and enhancements, and align to Model Experience workflows when possible.

What help do we offer?

To help you better identify gaps, reduce risks, and motivate change, we’ve created the Information Blocking Assessment where we help attendees:

  • Develop a plan to meet information blocking requirements
  • Create processes for organizational compliance
  • Assess EHR configuration recommendations to mitigate risk
