EDI 278N: Hospital Admission Notification

Use the Hospital Admission Notification (278N) transaction to exchange admission notification data between an inpatient facility and UnitedHealthcare in a standard format.

Similar to the HIPAA 278 transaction that you may already use to submit authorizations or referrals, the EDI 278N is the easiest, most efficient way to communicate facility admissions. It can be transmitted directly to UnitedHealthcare or through a clearinghouse in either batch or real-time format.


Hospitals that have implemented EDI 278N experience an improvement in notification submissions within 24 hours.

With EDI 278N transactions, you can:

  • Streamline administrative tasks and increase productivity
  • Reduce administrative costs through automation
  • Increase data accuracy by reducing manual errors
  • Confirm a notification of admission is on file in the form of a service reference number that is generated upon registration
  • Submit notification of discharge

Getting Started

You can contact your vendor or clearinghouse. Most clearinghouses already send 278N transactions to UnitedHealthcare and can work with you to submit notifications in the appropriate format.
