CUSTODIAL PACKAGE AUTOMATED LAB INSTRUMENTS
USAGE Private
TYPE Routine
DBIC APPROVAL STATUS APPROVED
ROUTINE LA7VHLU6
NAME LAB CODE MAPPING
GENERAL DESCRIPTION 
The routine LA7VHLU6 is used to resolve standardized
codes such as LOINC, SNOMED CT and other code sets when processing HL7
messages to internal data structures within the LAB DATA file (#63) for data
related to Microbiology, Surgical Pathology, Cytology, and Electron
Microscopsy.
STATUS Active
KEYWORDS
  • SNOMED CT
  • LOINC
  • CODE MAPPING
  • LAB HL7
DURATION Till Otherwise Agreed
ID LA7VHLU6
COMPONENT/ENTRY POINT
COMPONENT/ENTRY POINT COMPONENT DESCRIPTION VARIABLES
HL2LAH 
The entry point HL2LAH^LA7VHLU6 takes a LOINC code as
input and returns a pointer into the Organism subfile (63.3) of the Lab Data
file (63).  This pointer identifies where the antibiotic sensitivity record is
to be stored in VistA.
VARIABLES TYPE VARIABLES DESCRIPTION
CODE Input 
Represent the code identifier from the code system to
be resolved.
TEXT Input 
Code text related to the code being resolved.
NCS Input 
Name of code system referenced in the CODE variable.
VERSION Input 
The version of the code system being resolved.
LA76248 Input 
Related Lab Messaging configuration entry in LA7
MESSAGE PARAMETER File (#62.48) for non-standard code lookup when code is only
for a specific interface (optional). Usually used when code/code system is a
local code and only applicable to a specific interface.
LA7SS Input 
Specific lab subscript to screen standard codes -
used when same code used in multiple areas (optional). Subscripts supported
are "CH", "MI", "SP", "CY" and "EM".
LA7Y Output 
CONCEPT^SUBSCRIPT^FILE/SUBFILE^FIELD NUMBER^SCT
HIERARCHY ^OVERRIDE CONCEPT(optional)^OVERRIDE FILE/SUBFILE (optional)

Where:
CONCEPT = pointer to related concept in LAB MAPPING FILE (#62.47)
SUBSCRIPT = subscript of LAB DATA file (#63) "CH", "MI", "SP", "CY", "EM"
FILE/SUBFILE = file or subfile number of related entry
FIELD NUMBER = field number of related file/subfile to store value.
SCT HIERARCHY = SNOMED CT hierarchy of related concept

<optional return values>
OVERRDIE CONCEPT = pointer to related concept in LAB MAPPING FILE (#62.47)
that can be used when the regular related concept is
unable to accommodate the value.
OVERRIDE FILE/SUBFILE = file or subfile number of related entry of
override concept
SUBSCRIBING PACKAGE
SUBSCRIBING PACKAGE SUBSCRIBING DETAILS
JAL FEDERAL HEALTH CARE CENTER 
In its Lab Order Portability feature, the Federal
Health Care Center provides a capability to receive Lab orders, accessions and
clinical data from DoD and enter the information into the legacy VistA
database.  For antibiotic susceptibility information in Lab Micro results, we
need to determine the mapping of a LOINC code encoded in an HL7 message to the
local VistA Lab antiobiotic storage field in the LAB DATA file (#63).  The
entry point HL2LAH will resolve the LOINC code to the internal storage
location.
