Association of a
with a Data Control Used for Entering a Numeric or Other ValueWhen a value is entered in this control it is labeled with the appropriate Concept
Identifier and added to the record.

When selections are made using this control the appropriate Concept identifier is
added to the record.
Association of Concepts with a Particular Combination of Values or the Result of a Computation Involving Several Items of Previously Entered Data:
Figure 39 Two examples of how data entry of specific values can be foundation for
automatic addition of appropriate SNOMED CT clinical findings.
When specific values are entered the appropriate (defined) Concept identifier is added
to the record. The above examples show how specific numeric values can lead to specific
clinical findings, based on pre-defined rules.
The example at the bottom of Figure 39, illustrate that the BMI can be automatically
calculated by the entered values for body weight and height. Moreover, it is possible
to develop rule-based coding (i.e. algorithms that assign BMI values between 20 and
24 to the SNOMED CT Concept 35425004 | normal body mass index |, or to a more specific Concept 412768003 | body mass index 20-24 - normal |.
