This value set has an inline code system http://hl7.org/fhir/allergy-intolerance-criticality, which defines the following codes:

Code	Display	Definition
CRITL	Low Risk	The potential clinical impact of a future reaction is estimated as low risk: exposure to substance is unlikely to result in a life threatening or organ system threatening outcome. Future exposure to the Substance is considered a relative contra-indication.
CRITH	High Risk	The potential clinical impact of a future reaction is estimated as high risk: exposure to substance may result in a life threatening or organ system threatening outcome. Future exposure to the Substance may be considered an absolute contra-indication.
CRITU	Unable to determine	Unable to assess the potential clinical impact with the information available.

Level

A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies

Source

The source of the definition of the code (when the value set draws in codes defined elsewhere)

Code

The code (used as the code in the resource instance)

Display

The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
