VSAB: CPT2012, MTHCH2012

Summary of Changes

No changes have been made to the format of original data files or to Metathesaurus source processing.     

Source Provided Files:


The UMLS uses tab-delimited CPT files submitted by the AMA. The files used for 2012 are:
  • LONGULT.txt
  • MEDU.txt
  • MODUL.txt
  • SHORTU.txt
  • cpt-2011-corrections.pdf

Identifiers:


Identifiers are assigned as follows:
  • CODE: For CPT atoms: The CPT Code in the appropriate file (e.g. in LONGULT.txt for a PT).
    For MTHCH atoms: An MTHU# is generated during Metathesaurus source processing
  • SAUI: Not Applicable
  • SCUI: Same as CODE
  • SDUI: Not Applicable

Atoms (MRCONSO):

  (return to top)
SAB Term Type Origin
CPT AB CODE = value of CPT Code in SHORTU.txt
STR = value of CPT Short Description in SHORTU.txt
SCUI = value of CPT Code in SHORTU.txt
SUPPRESS = "Y"
CPT MP CODE = value of the Code indicated in MODUL.txt
STR = value of the CPT Modifier in MODUL.txt
SCUI = value of the CODE indicated in 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 first ":" on a given line. Data appearing after the ":" is included in the "CPF" attribute.
CPT PT CODE = value of CPT Code (positions 1-5) in LONGULT.txt
STR = value of CPT Long Description (positions 7 through length of long descriptor) in LONGULT.txt
SCUI = value of CPT Code (positions 1-5) in LONGULT.txt
CPT SY CODE = value of CPT Code (positions 1 through 5) in MEDU.txt
STR = value of CPT Medium Description (positions 7 through 55) in MEDU.txt, with non-ascii characters converted to ascii using the lvg tool
SCUI = value of CPT Code (positions 1 through 5) in MEDU.txt
MTHCH HT CODE = MTHU#, assigned during Metathesaurus source processing
STR = value of Metathesaurus Hierarchical Term
SCUI = MTHU#, assigned during Metathesaurus source processing
Note: The standard CPT data files distributed by the AMA do not include a hierarchy. The National Library of Medicine uses the printed book and other resources to generate a hierarchy during Metathesaurus source processing. This hierarchy has not been reviewed by the AMA and is attributed to SAB = "MTHCH".

Attributes (MRSAT):

  (return to top)
Attribute Name Origin
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.

Definitions (MRDEF):

  (return to top)

No definitions are included with the standard format CPT release.


Relationships (MRREL):

  (return to top)
REL RELA
Inverse RELA
ORIGIN
CHD
PAR
(no rela) Hierarchy created by the NLM during Metathesaurus source processing. This hierarchy has not been reviewed by the AMA, and is attributed to SAB = "MTHCH."
RN
RB
  Relationships are created during Metathesaurus source processing to connect related codes, based on string parsing. For example, "Anesthesia for procedures on arteries of forearm, wrist, and hand; embolectomy" (code 01842) is narrower than "Anesthesia for procedures on arteries of forearm, wrist, and hand; not otherwise specified" (code 01840). There may be inconsistencies in these relationships due to issues such as inconsistent punctuation. These relationships are not submitted or reviewed by the AMA and are attributed to SAB= "MTHCH" .
RO   Relationships are created during Metathesaurus source processing to connect related codes, based on string parsing. For example, "Anesthesia for closed chest procedures; needle biopsy of pleura" (code 00522) is given an RO relationships to "Anesthesia for closed chest procedures; pneumocentesis" (code 00524). There may be inconsistencies in these relationships due to issues such as inconsistent punctuation. These relationships are not submitted or reviewed by the American Medical Association (AMA), and are attributed to SAB = "MTHCH".
SY expanded_form_of
has_expanded_form
Connects a "PT" with its "SY" and "AB"

Mappings (MRMAP):

  (return to top)

No mappings are supplied by the AMA, however mappings from LNC215 to CPT2005 are included in the Metathesaurus.
