The master allergy list contains the allergies that can be added to a patient's allergy list (Patient Allergies).

To add to the allergy list or edit an existing allergy:

1. In the Main Menu, click Lists, Allergies or Setup, Chart, EHR (EHR Setup Window), Allergies.
   

   Allergies are listed alphabetically. To show allergies marked hidden, check the Show Hidden box.

2. Click Add, or double click an allergy to edit.
   
3. Description: Enter the allergy name.
4. Only used in EHR for CCDS: Most non-EHR offices can ignore these.

   Allergy Type: A value is required in order for the allergy to list on a EHR Continuity of Care Document (CCD)(e.g. Summary of Care).

   Allergen: Only one value (UNII or Medication) can be entered, not both.

   • UNII: Used for ingredient allergies (e.g. latex, peanuts). Enter a UNII to show this allergy on the CCD. Must be manually entered as a 10 character, uppercase, alphanumeric code. To search for UNII codes see http://fdasis.nlm.nih.gov/srs/srs.jsp.
   • Medication: Click [...] to select from the Medications List. To show on an a CCD, medication allergies must be associated with medications that have an RxNorm. Click None to clear the box.
5. Click OK to save.

Is Hidden: Check the box to hide the allergy so it can't be selected for other patients. It will continue to show for patients already using it.

Delete: Remove an allergy. Allergies in a patient's allergy list cannot be deleted.
