Defined as in the CK data type (see Section 2.8.5, "CK - composite ID with check digit") except that an ST data type is allowed instead of an NM data type.
Defined as in the CK data type (see Section 2.8.5, "CK - composite ID with check digit" except that an ST data type is allowed instead of an NM data type. The check digit in this data type is not an add-on produced by the message processor. It is the check digit that is part of the identifying number used in the sending application. If the sending application does not include a self-generated check digit in the identifying number, this component should be valued null.
Defined as in the CK data type (see Section 2.8.5, "CK - composite ID with check digit". Refer to HL7 table 0061- Check digit scheme for valid values.
Note: The check digit and code identifying check digit scheme are null if ID is alphanumeric. |
The assigning authority is a unique name of the system that creates the data. It is an HD data type. It is equivalent to the application ID of the placer or filler order number (see Chapter 4). Assigning authorities are unique across a given HL7 implementation.
A code corresponds to the type of identifier. In some cases, this code may be used as a qualifier to the "Assigning authority" component. Refer to user-defined table 0203 - Identifier type for suggested values.

Definition: the place or location identifier where the identifier was first assigned to the patient. This component is not an inherent part of the identifier but rather part of the history of the identifier: as part of this data type, its existence is a convenience for certain intercommunicating systems.
