This code system http://hl7.org/fhir/comparison/CodeSystem/5dc6e6ac-f2b5-4b67-9051-62dc8933b91a-60 defines codes, but no codes are represented here
| Code | Display | Definition |
| certain | Certain Match | This record meets the matching criteria to be automatically considered as a full match. |
| probable | Probable Match | This record is a close match, but not a certain match. Additional review (e.g. by a human) may be required before using this as a match. |
| possible | Possible Match | This record may be a matching one. Additional review (e.g. by a human) SHOULD be performed before using this as a match. |
| certainly-not | Certainly Not a Match | This record is known not to be a match. Note that usually non-matching records are not returned, but in some cases records previously or likely considered as a match may specifically be negated by the matching engine. |
