Patient ID
2007-05-08
Definition: This field has been retained for backward compatibility only. The arbitrary term of “external ID” has been removed from the name of this field. The repetition, assigning authority, healthcare facility, and identifier type code attributes of PID-3 - Patient Identifier List allow for distinctive identifier representation. This field remains for systems with a negotiated understanding of “external.” It is recommended to use PID-3 - Patient Identifier List for all patient identifiers.
When used for backward compatibility, this field is valued when the patient is from another institution, outside office, etc., and the identifier used by that institution can be shown in this field. This may be a number that multiple disparate corporations or facilities share. Refer to HL7 Table 0061 - Check Digit Scheme.
