The UMLS uses files publicly available at www.loinc.org.
In addition, the UMLS receives a file of abbreviations with expansions called 'Loinc_<ver>_Abbreviations.csv'.
LOINC Identifiers in the UMLS are generally based on field 1 of Loinc.csv, or field 1 of Part.csv (PartNumber). For some termtypes, the atom may be associated with multiple LOINC entities. For example, a component may be a part of multiple fully-specified names. In these cases, the atom (e.g. a CN, or Official Component Name), is assigned an MTHU# during Metathesaurus source processing.
Expanded forms of certain atoms are created during Metathesaurus source processing by applying abbreviation expansions extracted from the LOINC Users Guide. In these cases, the expanded form is generally assigned the same identifier as its original form. Expansions may also include converting patterns such as "little e" or "super little b" to "e" or "^b" respectively.
