As of April 23, 2024 all documentation of the ZAP can be found at https://clinicalguide.zushealth.com/docs/allergies


The Allergies component allows providers to understand patient allergies and their reactions. The Allergies component leverages summarized allergy histories, including allergies recorded by other providers.

Users can:

  • See a deduplicated* list of allergies reported by your organization and other providers
  • See a chronological history of allergies recorded by your organization and other providers
  • View source documents that mentioned each allergy

*Note: Some allergies information does not come with codes from standard terminologies (e.g., RxNorm), which may reduce the impact of deduplication. We will consider improving our deduplication over time.

Allergies List

The Allergies list shows allergies from your organization and outside provider records, summarized by RxNorm code (where available) so users have a simple, deduplicated allergies list to review.

  • Note: the Allergies component will be blank if Zus did not find allergies in a patient's medical history or if your organization has never requested medical history for a patient through Zus.

The red dot to the left of the "Allergies" title indicates the presence of new data. New allergies are displayed in bold font.

You can mark a new allergy as read by clicking "Mark As Viewed" above or by clicking on the allergy to view its details, which automatically marks the allergy as viewed.

If you believe an allergy is no longer active for a patient or was entered in error, you can click "Dismiss" to remove it from the Allergy list. Select "+ Add Filters" and click "Show Dismissed Records" to show dismissed allergies, which will appear in gray font.

Allergies History

Allergies History is available for all allergies from your organization and from outside providers.


The summary is a quick view of the most recent available information for an allergy.


History shows all individual records in the ZAP associated with a given allergy. Expanding a record provides additional available detail such as the reporting organization, onset date, and reaction. Clicking on the "Source Document" link will show the clinical document the allergy was extracted from.
