Notes

CPT data files are submitted by the American Medical Association (AMA). The files processed for the UMLS Metathesaurus are available for licensing at the AMA Bookstore.
The information provided here applies explicitly to the English version of CPT. The Spanish translation of CPT (CPTSP) was last updated in 2001, and much of the information on this page is not applicable.

The UMLS does not include Guidelines or SNOMEDCT mappings from the CPT DTK files due to licensing restrictions.

Summary of Changes:

New ATNs:
CODING_TIP
CITATION
PROPRIETARY_NAME
REPORTABLE - T/F indicates a reportable CODE. Previously, this information was embedded in the TTY. As of this release, the UMLS will include ADM codes, which will be TTY = PT, but REPORTABLE = F.

"ADM" is a new CPT_LEVEL value:
Multianalyte Assays with Algorithmic Analyses (MAAA), from Appendix 0; The codes for these end in "M", e.g. 0002M. T

The following new data was not inverted:
Level = POS (place of service)
HCPCS Level II Codes

Consumer-friendly Descriptors
Property_DTK_pipe.txt In the Property File, a concept is represented by a set of lines that all have the same CONCEPT ID. Some of the concepts in the Property File correspond to reportable CPT codes, some were constructed by the AMA for the 2014 CPT DTK, and some were drawn from SNOMED CT.
Relationship_DTK_pipe.txt In the Relationship File, relationships between two concepts are represented.
Type_DTK_pipe.txt
The Type File provides a succinct representation of the types of information contained in the Property File and the Relationship File. The PROPERTY TYPE ID column from the Property File and RELATIONSHIP TYPE ID column from the Relationship File both correspond to the TYPE ID number from the Type File. Thus, the Type File enables a user to see at a glance all of the categories of relationship types used in the 2014 CPT DTK
