Vocabulary Work Group

Maturity Level: 2

Standards Status: Trial Use

4.3.9.1 Summary

Source	CPT is made managed by the American Medical Association
System	The URI http://www.ama-assn.org/go/cpt identifies the CPT code system
Version	Where a version is appropriate, use the year of release e.g. 2014
Code	"Code" in the CPT tables (a 5-character code)
Display	The correct display for a CPT code is one of the descriptions associated with the code. There are multiple description options that vary by length and target audience, including: long descriptions, medium descriptions, short descriptions, consumer friendly descriptors and clinician descriptors.
Inactive	For CPT Link ontology licensees, inactive codes are listed in the History folder in the “Deleted_DTK_pipe” and “Deleted_DTK_tab” files. For CPT flat file licensees, codes that exist in the flat file are active and codes that are not present are inactive. Deletions/changes between the previous release year and current release year are displayed in the “Appendix B” PDF.
Subsumption	No Subsumption relationships are defined by CPT
Filter Properties	None defined

4.3.9.2 Version Issues

A new code-year of CPT is released by the end of August each year for use the subsequent calendar year. CPT versions are identified simply by the year of their release. For example, the CPT 2020 codes are released at the end of August 2019 and intended for use during the 2020 calendar year.
