Substance Reactant for Intolerance

Built for C-CDA 2.x\nThe intention is that instance content will be determined from the concepts in this grouping value set but values will be determined by searching through the grouped value sets in priority order, and when a concept matching the intension (by preferred name or any synonym), only that particular concept identifer will be included, and not any additional similar or matching identifiers. In this way overlaps in concept representation will be resolved. The drug class value set aligns with work based on informative analysis of common reactants associated with intolerances. This will not be a full list of all drug classes. Does not include vaccines
