The <code> element represents the kind of allergy observation made, to a drug, food
or environmental agent, and whether it is an allergy, non-allergy intolerance, or
unknown class of intolerance (not known to be allergy or intolerance). The <code>
element of an allergy entry shall be provided, and a code and codeSystem attribute
shall be present.

Choice |
|
|
The coded form of the observation value can be used:
- to contain a description of the allergy or adverse reaction.
- to indicate known absent conditions or the nonavailability of information.
Elements to choose from:
- hl7:value[1]
- hl7:value[2]
|
hl7:value
|
CD |
0 … 1 |
C |
A description of the allergy or adverse reaction. The preferred approach would be
to include the agent in the participant structure. If distinct agent data cannot be
provided, a 'diagnosis' can be included in the value.

The substance that causes the allergy or intolerance should be specified in the <participant>
structure. This is the preferred way an allergy is supposed to be expressed. However it is recognized that in some contexts a controlled vocabulary is used for
describing the allergy to a substance; or for asserting known absence or unavailability
of information. In this case the <participant> structure shall be omitted. The agent responsible for an allergy or adverse reaction is not always a
manufactured material (for example, food allergies), nor is it necessarily consumed.
The following constraints reflect limitations in the base CDA R2 specification, and
should be used to represent any type of responsible agent, i.e., use playingEntity
classCode = "MMAT" for all agents, manufactured or not.

IF the observation/value element is present and valued with a code indicating the
known absence/no information on allergies THEN the observation/participant element
used to describe the agent SHALL be omitted.

An allergy entry can record the reactions that are manifestations of the allergy or
intolerance as shown below. It uses a related entry (<entryRelationship>) that indicates
the manifestations (typeCode='MFST') the reported allergy or intolerance. These are
events that may occur, or have occurred in the past as a reaction to the allergy or
intolerance<entryRelationship typeCode='MFST'>
