VSAB: CPT2016

Summary of Changes

"CPT DTK" is now referred to as "CPT Link." No changes were made to the basic data format, however there are several changes and additions, including:

  • Many new property types
  • The UMLS received permission to release concepts treed under "Guidelines," as well as relationships between CPT and SNOMEDCT_US.
  • The UMLS now processes the "Relationship Groups" file. The RG field in MRREL.RRF will now be populated for CPT, indicating a set of relationships should be looked at in conjunction. In addition, the CPT data file includes "Or groups," indicating disjunctive expressions.
  • The AMA now releases Code Edits, which have been derived from explicit instructions within the guidelines, parentheticals, and specific code designations. These are represented in the UMLS as attributes or relationships, as appropriate.

Source Provided Files:

Documentation:
Extensive documentation is provided, including:

File Name Description
2017 Consumer Friendly Descriptors README.docx User guide for Consumer Descriptor data
2017 Clinician Descriptors README.docx User guide for Clinician Descriptor data
2017_CPT_Link_ReadMe_20160901.pdf User guide for main data files
2017_CPT_Sourced_Code_Edits.docx User guide for Code Edits file

Data:

CPT Link files are available in both "tab" and "pipe" delmited formats. The UMLS uses the following data files:
File Name Description
ClinicianDescriptor_DTK_pipe.txt Clinician Descriptors
ConsumerDescriptor_DTK_pipe.txt 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 CPT Link, and some were drawn from SNOMED CT. 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 the 2014 CPT DTK
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"
