Component definitions for: CV : Code_value

code_system :: OID

An object identifier referring to the code system that defines the code value. The OID allows to unambiguously refer to standard HL7 codes, other standard code systems, as well as local codes. HL7 assigns OIDs to its code tables as well as to external standard code systems that are being used with HL7. Local sites can use their OID to construct a local code system identifier that is globally unique.

code_system_version :: ST

A version descriptor defined specifically for the given code system.

print_name :: ST

A sensible name for the code as a curtesy to an interpreter of the message. THE PRINTNAME HAS NO MEANING, it can never be sent alone and it can never modify the meaning of the code value

replacement :: ST

A name for the concept to be used in case that the concept is not codeable in the specified coding system. If the value attribute is set, the replacement attribute MUST NOT be set. In no way can a replacement string modify the meaning of the code value

CONDITIONAL: iff value not set.

value :: ST

This is the plain symbol, like "784.0"
