What's New
open@epic Conference 2026
Date: 10/21/26
Open@Epic is underway. Topics include connecting external agents to Epic, medication price transparency, FHIR notifications, and more. See the conference overview page for additional takeaways and session slides.
New Data Sharing Playbooks and App Templates
Date: 10/21/26
We've published 5 new playbooks to help developers get started with recommended practices. The new playbooks are Diagnostic Image Exchange, Staff Duress, Hospital Utilization Review Creation, Payer Medical Necessity Guideline Creation, and Histocompatibility Laboratory Information Systems. We've also published a developer tutorial for context and content sharing with FHIRcast, a standard for real-time exchange that fits a wide variety of use cases.
We now have over 50 playbooks, and more than 30 include app templates. A template lets developers create a client ID in one click with the recommended APIs already selected for their use case. Developers can review and edit the selected APIs to customize the app, which streamlines app creation while still allowing for differences between apps.
USCDI v5 and More FHIR Enhancements
Date: 10/21/26
Epic now supports USCDI v5 and US Core 8 in the August 2026 release.
With these enhancements, apps can:
- retrieve Advance Directives with new DocumentReference (Search, Read), Binary (Search, Read), and Observation (Search, Read) resources.
- read Patient Care Experience Preference data with new Observation (Search, Read) resources
- search DiagnosticReport (Results) and Observation (Labs) with _lastUpdated by the date a record was last changed, so apps can pull only new or updated result data since the app's last sync instead of re-fetching everything.
- use over 30 other new data elements, including a patient's medication adherence information in the MedicationRequest resource (Search, Read).
In addition to USCDI v5, we've enhanced FHIR support in August 2026 in other ways, such as extending MedicationAdministration (Search, Read) support to all regions.
