Map Sets
A map set does not simply merge two terminologies. Instead, it is a unidirectional mapping from a source to a target terminology using a specified relationship type – and it can be complex. Different requirements could produce different map sets even between the same two terminologies. Some use cases are particularly difficult, such as requiring an equivalent map for all codes in the source terminology.
Standard terminologies have provided some starter sets, such as SNOMED CT to ICD-10-CM from the NLM. The 3M HDD contains these starter map sets but also extends them according to your needs, and new, specific map sets can be developed and maintained for your organization. Our versioning ability allows the seamless management of different terminology releases – as well as multiple versions of the map sets – to support interoperability between organizations and applications.
