This file contains classification codes from multiple classification systems (i.e., ICD, CPT, DSM, SNOMED, Title 38, NANDA, NIC, COSTAR, COSTART, CRISP, etc.).

Global: ^LEX(757.02,

Domain: Non-Clinical

Properties

Label/Field Name Field # Description Datatype Attributes Range
Expression
  expression
.01 Pointer to the expression in the Expression file #757.01 to which a
classification code (i.e., ICD, CPT, DSM code) has been assigned. This
pointer links the code to an expression. This expression can be a Major
Concept, a Synonym or a Lexical Variant of either the Major Concept or the
Synonym.
POINTER INDEXED

Expressions-757_01
Code
  code
1 Classification Code as described by a controlled vocabulary (i.e., ICD,
CPT, etc).
STRING REQUIRED  
Classification Source
  classification_source
2 Pointer to the classification system (ICD/CPT/DSM etc) described in the
Coding Systems file (#757.03) from which the code (field 1) is derived.
POINTER REQUIRED Coding_Systems-757_03
Major Concept
  major_concept
3 Pointer the the Major Concept in the Major Concept Map file #757 to which a
classification code (i.e., ICD, CPT, DSM code) has been assigned. This pointer
links the code to the Major Concept of the expression defined in the .01 field
(Expression).
POINTER INDEXED
REQUIRED
Major_Concept_Map-757
Preference Flag
  preference_flag
4 Some codes within a coding system are linked to multiple terms. This flag
indicates the preferred term of a code (within a classification system),
providing a one-to-one relationship between codes and terms. This field is
only populated when a code is linked to multiple terms.
ENUMERATION   PREFERRED TERM: 1
OTHER THAN PREFERRED TERM: 0
Deactivation Flag
  deactivation_flag
5 This field indicates that a code formerly in use by the Lexicon has
been deactivated and should not be used in lookups or displays.
ENUMERATION   DEACTIVATED CODE: 1
Primary Flag
  primary_flag
6 If an expression has multiple codes from the same classification system
(i.e., ICD, CPT, etc) then one will be flagged as the primary code and the
others will be flagged as supplemental. If there is only one code of a
specific classification system then it will be flagged as the primary code.
ENUMERATION REQUIRED PRIMARY CODE: 1
SUPPLEMENTAL CODE: 0
Activation Status
  activation_status
8 This is a listing of the activation history
for a code.
OBJECT   Activation_Status-757_28
Legacy Code
  legacy_code
13 This field stores a code that under a different version of the coding
system represents the same concept as the code in the current coding
system. E.g. SNOMED CT (the current SNOMED code system) code 123456789
might have a SNOMED 2 (legacy code system) legacy code of F-12345.
