8.1 Code Value
Code Value (0008,0100) is an identifier that is unambiguous within the Coding Scheme denoted by Coding Scheme Designator (0008,0102) and Coding Scheme Version (0008,0103).
The Long Code Value (0008,0119) or URN Code Value (0008,0120) is only used for codes that exceed the 16 character size limit of Code Value (0008,0100). If the code value length exceeds 16, the Code Value (0008,0100) shall not be present. If the code value length is 16 characters or less, the Code Value (0008,0100) shall contain the code and neither Long Code Value (0008,0119) nor URN Code Value (0008,0120) shall be present. The URN Code Value (0008,0120) shall be used for codes that are represented using URN or URL notation. The Long Code Value (0008,0119) shall be used for codes that are represented using other notations and that exceed 16 characters in length.
Note
The Code Value is typically not a natural language string, e.g., "76752008".
