4.3.14.21.2 AllergyIntoleranceCertainty

Statement about the degree of clinical certainty that a specific substance was the cause of the manifestation in a reaction event.

This code system http://terminology.hl7.org/CodeSystem/reaction-event-certainty defines the following codes:

Code	Display	Definition
unlikely	Unlikely	There is a low level of clinical certainty that the reaction was caused by the identified substance.
likely	Likely	There is a high level of clinical certainty that the reaction was caused by the identified substance.
confirmed	Confirmed	There is a very high level of clinical certainty that the reaction was due to the identified substance, which may include clinical evidence by testing or rechallenge.
unknown	Unknown	The clinical certainty that the reaction was caused by the identified substance is unknown. It is an explicit assertion that certainty is not known.
