Table source: Online definitions.

Table purpose: High-level definitions for current procedural terminology (CPT) codes.

Number of rows: 134

Links to:

  • CPTEVENTS on CPT_CD between MINCODEINSUBSECTION and MAXCODEINSUBSECTION

Brief summary

This table gives some high level information regarding current procedural terminology (CPT) codes. Unfortunately, detailed information for individual codes is unavailable.

Important considerations

  • Unlike all other definition tables, D_CPT does not have a one to one mapping with the corresponding CPT_CD in CPTEVENTS, rather each row of D_CPT maps to a range of CPT_CD.

Detailed Description

D_CPT provides information about CPT codes, specifically it provides the overall purpose of the procedure and in some cases the body system related to the procedure.

CATEGORY

CATEGORY is a integer which identifies the category of the CPT code.

SECTIONRANGE, SECTIONHEADER

SECTIONRANGE defines the range of codes for the given section, and SECTIONHEADER provides the description of the given section. There are 8 possible sections:

  • Evaluation and management
  • Surgery
  • Radiology
  • Anesthesia
  • Emerging technology
  • Pathology and laboratory
  • Performance measurement
  • Medicine

Note that the evaluation and management tends to represent administrative or generic costs.

SUBSECTIONRANGE, SUBSECTIONHEADER

Similarly as for the sections, SUBSECTIONRANGE defines the range of codes for the given subsection, and SUBSECTIONHEADER provides the description of the given subsection. The subsection provides extra detail which can be useful, for example, when the section header is 'Anesthesia' the subsection provides information on the general anatomical region for the anesthesia.

MINCODEINSUBSECTION, MAXCODEINSUBSECTION

These columns provide numeric representations of minimum and maximum value in the SUBSECTIONRANGE column. This facilitates joining the CPTEVENTS table to the D_CPT table on CPT_CD.
