Manifest MedEx is California’s nonprofit health data network impacting the lives of 23 million patients through partnerships with more than 600 health care organizations. Manifest MedEx is proud to help California hospitals meet the new CMS ADT event notification regulations.


These notifications give primary care and post-acute providers the ability to proactively monitor and support their patients through the entire continuum of care.

The new CMS Rule requires hospitals, including psychiatric hospitals and critical access hospitals to send electronic event notifications to a patient’s care team when a patient is admitted, discharged or transferred (ADT) to another health care facility.


Hospitals must be in compliance with the CMS Interoperability and Patient Access Final Rule (CMS-9115-F)
by May 1, 2021 in order to meet the Medicare and Medicaid Conditions of Participation (CoP).
