Terminology considerations

Terminology – Code Systems

Laboratory test code systems are essential for configuring electronic reporting.
Within the working group, several independent code systems were defined, representing subsets of items from the national code system NČLP.

Defined code systems:

• Material codes (sample origin)
• Basic examination method codes
• Agent codes (detected microorganisms)
• Specific method target codes

Material Code System

This code system is a subset of items from the NČLP microbiology system list
NCMPSYST.

The list of items is provided in Annex 1.

Basic Method Code System

This code system is a subset of items from the NČLP procedure list
NCLPPROC.

The list of items is provided in Annex 1.

Agent Code System

This code system reflects the infectious agents monitored under disease surveillance.
It is a subset of items from the NČLP microbiology agent list
NCMPAG.

The code system is mapped to SNOMED CT and may be extended as needed.
The list of items is provided in Annex 1.

For the pilot project under SCOPE-IS, the following infectious agents were selected:

ICD-10 Code	Diagnosis
A02.0	Salmonella enteritis
A04.5	Enteritis, agent: Campylobacter
A37.0	Whooping cough, agent: Bordetella pertussis
B05	Measles
B15	Acute hepatitis A
B16	Acute hepatitis B
B17.1	Acute hepatitis C
B17.2	Acute hepatitis E

Antibiotic Susceptibility Code System

This code system is a subset of items from the NČLP code list for antibiotic susceptibility assessment
LMHCN.

For early warning reporting purposes, the key values are:

Code	Meaning
C	susceptible
I	susceptible, increased exposure
R	resistant
