AllergyIntolerance - voc_ExternalSystems

I am looking for urn:oid (Coding System) to capture allergies using Concept Ids made available by First DataBank.

Examples for FDB allergies with different concept types:

(CONCEPT TYPE CODE=006)
FDB HIC SEQN 118
FDB HIC DESC CHOLERA VACCINE,WHOLE CELL,RECOMB.B SUBUNIT-KILLED
CHOLERA VACCINE,WHOLE CELL,RECOMB.B SUBUNIT-KILLED

(CONCEPT TYPE CODE=001)
FDB HIC SEQN 118
FDB HIC DESC Yellow Dye

(CONCEPT TYPE CODE=002)
FDB HIC SEQN 118
FDB HIC DESC Pampers Premium Unisex Poly

I found the following URL on HL7 org, but not sure if the following coding system is appropriate to be used as part of CodeableConcept (coding.system)

https://www.hl7.org/documentcenter/public/standards/vocabulary/vocabulary_tables/infrastructure/vocabulary/voc_ExternalSystems.html

  1. “system”: “urn:oid:2.16.840.1.113883.6.63”

Code System: First DataBank Diagnostic Codes [2.16.840.1.113883.6.63] (FDDX)
Description:
First DataBank Diagnostic Codes (this seems more inline with ICD codes)

  1. “system”: “urn:oid:2.16.840.1.113883.6.64”

Code System: First DataBank Drug Codes [2.16.840.1.113883.6.64] (FDDC)
Description:
First DataBank Drug Codes (not sure if this is appropriate for mapping to allergies)

  1. “system”: “2.16.840.1.113883.3.84”

Code System: FDB HIC Code [2.16.840.1.113883.3.84] (FDBHICCode) - this seems more appropriate

Your guidance is much appreciated!

Thank you!

It is best to use URIs not based on OIDs. See http://build.fhir.org/terminologies-systems.html for existing code systems and a pointer to registering code systems.
The ones you have found look plausible to me. But I am not an expert here.
