All substances that may need to be represented in the context of health care related
activities. This value set is quite broad in coverage and includes concepts that may
never be needed in a health care activity event, particularly the included SNOMED
CT concepts. The code system-specific value sets in this grouping value set are intended
to provide broad coverage of all kinds of agents, but the expectation for use is that
the chosen concept identifier for a substance should be appropriately specific and
drawn from the appropriate code system as noted:
prescribable medications should use RXNORM concepts, more specific drugs and chemicals
should be represented using UNII concepts, and any substances not found in either
of those two code systems, should use the appropriate SNOMED CT concept. This overarching
grouping value set is intended to support identification of prescribable medications,
foods, general substances and environmental entities.
Value set intensionally defined as a GROUPING made up of: Value Set: Medication Clinical
Drug (2.16.840.1.113762.1.4.1010.4) (RxNorm generic and brand codes); Value Set: Unique
Ingredient Identifier - Complete Set (2.16.840.1.113883.3.88.12.80.20) (UNII codes);
Value Set: Substance Other Than Clinical Drug (2.16.840.1.113762.1.4.1010.9) (SNOMED
CT codes).
