HL7 Table Identifier HL70301
Version
Status Active
Where Used HD.3, EI.4
Purpose and Use HL7-defined table of codes specifying the type of UID (Universal Identifier). Open Issue: Table 0301 has a mix of class and instance identifiers for namespaces, which is improper. The values for instances. such as CLIA, CLIP, CAP, and NPI. These were added for pragmatic issues related to older datatypes that were universally bound tand should not be here but are needed for implementation pragmatics. These should be annotated in Comment or Usage Notes that these are not universal ID types really.

Code Display Definition Deprecated
CAP College of American Pathologist Accreditation Number Allows for the ability to designate organization identifier as a "CAP" assigned number (for labs)
CLIA Clinical Laboratory Improvement Amendments Clinical Laboratory Improvement Amendments. Allows for the ability to designate organization identifier as a "CLIA" assigned number (for labs)
CLIP Clinical laboratory Improvement Program Clinical laboratory Improvement Program. Allows for the ability to designate organization identifier as a "CLIP" assigned number (for labs).  Used by US Department of Defense.
DNS Domain Name System An Internet host name, in accordance with RFC 1035; or an IP address. Either in ASCII or as integers, with periods between components ("dotted" notation).
EUI64 IEEE 64-bit Extended Unique Identifier IEEE 64-bit Extended Unique Identifier is comprised of a 24-bit company identifier and a 40-bit instance identifier. The value shall be formatted as 16 ASCII HEX digits, for example, “AABBCC1122334455”. The 24-bit company identifier, formally known as Organizationally Unique Identifier (OUI-24), is guaranteed to be globally unique. The 40-bit extensions are assigned by manufacturers. This identifier is often used in equipment interfaces (e.g., “MAC” address format for IPv4 & IPv6). [See http://standards.ieee.org/regauth/oui/tutorials/EUI64.html for a detailed explanation of the format.]
GUID globally unique identifier Same as UUID.
HCD CEN Healthcare Coding Identifier The CEN Healthcare Coding Scheme Designator
HL7 HL7 registration schemes HL7 registration schemes
ISO ISO Object Identifier An International Standards Organization Object Identifier (OID), in accordance with ISO/IEC 8824. Formatted as decimal digits separated by periods; recommended limit of 64 characters
L Local These are reserved for locally defined coding schemes.
L,M,N Local These are reserved for locally defined coding schemes.
M Local These are reserved for locally defined coding schemes.
N Local These are reserved for locally defined coding schemes.
NPI US National Provider Identifier Allows for the ability to designate organization identifier as a "NPI" assigned number (lab, any medical provider, can be a person or an organization)
Random Random Usually a base64 encoded string of random bits.

Note: Random IDs are typically used for instance identifiers, rather than an identifier of an Assigning Authority that issues instance identifiers

URI Uniform Resource Identifier Uniform Resource Identifier
UUID Universal Unique Identifier The DCE Universal Unique Identifier, in accordance with RFC 4122. Recommended format is 32 hexadecimal digits separated by hyphens, in the digit grouping 8-4-4-4-12
x400 X.400 MHS identifier An X.400 MHS identifier. Recommended format is in accordance with RFC 1649
x500 X500 directory Name An X.500 directory name
