This page lists specific source data elements and provides information on their representation in the UMLS Metathesaurus.
The complete English language CPT distribution includes the following:
File Name | Description |

2023 CPT Link ReadMe 20220909.docx | User guide for main data files |
File Name | Description |
---|---|
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 CPT Link, and some were drawn from SNOMED CT. |
RelationshipGroup_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 CPT Link |
Days.txt | Edits sourced from CPT instructions such as "Report 93228 only once per 30 days" |
Exclude.txt | Edits sourced from CPT instructions such as "Do not report 00326 in conjunction with 99100" |
ReportWith.txt | Edits sourced from CPT instructions such as "Use 44139 in conjunction with 44140-44147" |
Details on format of input files and representation of source data. Consult the CPT documentation for additional details.
