description: Prefixes mentioned on the _external_ list on the FHIR [Code Systems](https://hl7.org/fhir/terminologies-systems.html) page. This list is mostly complete. Notably, some entries that have not been curated: - HGVS (see discussion at [#460](https://github.com/biopragmatics/bioregistry/issues/460)) - [NUBC](http://www.nubc.org) (National Uniform Billing Committee) - could not find information about the terminology or its entries - [ICPC](http://www.ph3c.org/) (International Classification of Primary Care) _same_ - [GTIN](https://www.gs1.org/standards/id-keys/gtin) (Global Trade Item Number) _same_ - [MDC](https://www.iso.org/standard/37890.html) (Medical Device Codes) since that appears to be part of a larger ISO standard vocabulary that needs further investigation
