In accordance with NLM’s mapping assumptions, the Map can be used by users that are licensed to use both SNOMED CT and ICD-10-CM. SNOMED CT is owned by the International Health Terminology Standards Development Organisation (IHTSDO). The NLM is the U.S. Member of the IHTSDO and, as such, distributes SNOMED CT at no cost in accordance with the Member rights and responsibilities outlined in the IHTSDO's Articles. The license terms are incorporated into the License for Use of the UMLS Metathesaurus. Use of SNOMED CT is subject to the IHTSDO Affiliate license provisions and is free in IHTSDO Member territories including the United States, in low income countries, and for Qualifying Research Projects in any country.
