Notes: The current license agreement for including CPT in the Metathesaurus includes the above files.

The standard CPT data files distributed by the AMA do not include a hierarchy. The NLM uses the printed book and other resources to generate a hierarchy during Metathesaurus source processing. This hierarchy has not been reviewed by the AMA. In addition, the NLM generates relationships between CPT codes based on string parsing. The hierarchy and relalationships are attributed to SAB = "MTHCH".

Not included: All information from the CPT data files is included in the UMLS representation.  In a small number of cases, the 2012 included redundant or erroneous data, which was fixed or ignored as appropriate during Metathesaurus source processing, based on information found in cpt-2011-corrections.pdf and/or in the CPT printed book.

* Certain fields and files may not be directly processed because they contain redundant data.
