Coded ID according to a user-defined table, defined by the 8^th component. If the first component is present, either the source table or the assigning authority must be valued.

Retained for backward compatibility only as of v 2.5. See Professional Suffix component.

Used to specify an educational degree (e.g., MD). Refer to User-defined Table 0360 – Degree for suggested values.

The assigning authority is a unique identifier of the system (or organization or agency of department) that creates the data. It is a HD data type. User-defined Table 0363 – Assigning authority is used as the HL7 identifier for the user-defined table of values for the first sub-component of the HD component, <namespace ID>.

Note: When the HD data type is used in a given segment as a component of a field of another data type, User-defined Table 0300 - Namespace ID (referenced by the first sub-component of the HD component) may be re-defined (given a different user-defined table number and name) by the technical committee responsible for that segment.

By site agreement, implementers may continue to use User-defined Table 0300 – Namespace ID for the first sub-component.

The reader is referred to the PPN.23 and the PPN.24 if there is a need to transmit values with semantic meaning for an assigning jurisdiction or assigning department or agency in addition to, or instead of, an assigning authority. However, all 3 components may be valued. If, in so doing, it is discovered that the values in PPN.23 and/or PPN.24 conflict with PPN.94, the user would look to the Message Profile or other implementation agreement for a statement as to which takes precedence.

Contains the code identifying the check digit scheme employed.

Refer to HL7 Table 0061 - Check digit scheme for valid values.

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.

Note: When the HD data type is used in a given segment as a component of a field of another data type, User-defined Table 0300 - Namespace ID (referenced by the first sub-component of the HD component) may be re-defined (given a different user-defined table number and name) by the technical committee responsible for that segment.

This component describes when the activity was performed.

Note: If this field is not null, both the performing person and the time stamp must be valued.

Different name/address types and representations of the same name/address should be described by repeating of this field, with different values of the Name/Address Type and/or Name/Address Representation component.

Note: This new component remains in "alphabetic" representation with each repetition of the field using these data types. I.e. even though the name may be represented in an ideographic character set, this component will remain represented in an alphabetic character set.

In general this component provides an indication of the representation provided by the data item. It does not necessarily specify the character sets used. Thus, even though the representation might provide an indication of what to expect, the sender is still free to encode the contents using whatever character set is desired. This component provides only hints for the receiver, so it can make choices regarding what it has been sent and what it is capable of displaying.

This component contains the start and end date/times, which define the period during which this name was valid. See section 2.A.20, "DR - date/time range" for description of subcomponents.

Retained for backward compatibility only as of v 2.5. Refer to PPN.20 Effective Date and PPN.21Expiration Date. This component cannot be fully expressed and was identified as v 2.4 erratum.

The geo-political body that assigned the identifier in component 1.

See section 2.A.14.9, "Assigning Jurisdiction (CWE)" for further detail.

The agency or department that assigned the identifier in component 1.

See section 2.A.14.10, "Assigning Agency or Department (CWE)" for further details.
