VSAB: CPT2014

Summary of Changes

The UMLS is now using the Developers Toolkit Version of CPT (DTK), which is a set of relational-format files that include a hierarchy.

The resulting changes include:

Deprecated SAB/TTY: MTHCH/HT

New TTY: CPT/HT

New REL/RELA:  RT/has_panel_element

Deprecated REL/RELA:  BT/NT and RT with no RELA have been deprecated; previously, these were created during Metathesaurus source processing, based on substring matching.

Deprecated ATN:  CPT_CLINICIAN_DESC_ID - this data is no longer present in the Clinician files.

New ATNs:

ADDITIONAL_GUIDELINE
ADDON_CODE
CPT_LEVEL
DATE_CREATED
DATE_LAST_MODIFIED
DESCRIPTOR_EXTENSION
EXEMPT_MOD
FDA_APPROVAL_PENDING
MEASURE_DEVELOPER
MODERATE_CONSCIOUS_SEDATION

Source Provided Files:

Documentation:
    Extensive documentation is provided, including:
    2014 CONSUMER DESCRIPTORS ReadMe_FINAL.doc
    2014_CLINICIAN DESCRIPTORS_ReadMe_FINAL.doc
    2014_CPT_DTK_ReadMe_with_OWL_FINAL.doc

Data: 
   
DTK files are available in both "tab" and "pipe" delmited formats.  The UMLS uses the following data files:
    Relationship_DTK_pipe.txt
    Property_DTK_pipe.txt
    Type_DTK_pipe.txt
    ConsumerDescriptor_DTK_pipe.txt
    ClinicianDescriptor_DTK_pipe.txt

Identifiers:

Identifiers are assigned as follows:
  • CODE: 
    • TTY = PT, SY, AB, ETCF, ETCLIN:  Value of CPT_Code Property (Type Id = 104)
    • TTY = HT:  Concept Id value
    • TTY = MP:  Value of Modifier_Code Property (Type Id = 129)
  • SAUI: Not Applicable
  • SCUI: Same as CODE
  • SDUI: Not Applicable

STR = Value of Short_Descriptor (Type Id = 111) in Property_DTK_pipe.txt
SCUI = Same as CODE
SUPPRESS = "Y"
ETCF
CODE = Value of CPT_Code (Type Id = 104) in Property_DTK_pipe.txt
STR = Value of Consumer_Friendly_Descriptor (Type Id = 123) in ConsumerDescriptor_DTK_pipe.txt
SCUI = Same as CODE

Note:  TTY = HT is assigned when the Level Property (Type Id = 109) indicates that the concept is a Heading.
Values are:  H1, H2, H3, H4, H5, H5, HS, root. 
Concepts treed under the "H1-Guidelines" heading are not included in Metathesaurus source processing.
MP CODE = Value of Modifier_Code (Type Id = 129)
STR = Value of Descriptor (Type Id = 106) in Property_DTK_pipe.txt
SCUI = Same as CODE
SUPPRESS = "N"
PT CODE = Value of CPT_Code (Type Id = 104) in Property_DTK_pipe.txt
STR = Value of Descriptor (Type Id = 106) in Property_DTK_pipe.txt
SCUI =  Same as CODE
SUPPRESS = "N"
SY CODE = Value of CPT_Code (Type Id = 104) in Property_DTK_pipe.txt

CPF
The complete value of the modifier string from MODUL.txt. Note: Although the file MODUL.txt is not delivered in a set format, in general the modifier code can be found in character positions 1-2, and the "MP" string is found after the tab and before the ":" on a given line. Data appearing after the ":" is included in the "CPF" attribute.
