| Name | Code | URI | Type | Description |
| Specializes | Specializes | | Coding | The child code is a more narrow version of the concept represented by the parent code. I.e. Every child concept is also a valid parent concept. Used to allow determination of subsumption. Must be transitive, irreflexive, antisymmetric. |
| Generalizes | Generalizes | | Coding | Inverse of Specializes. Only included as a derived relationship. |
| internalId | internalId | http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-id | code | The internal identifier for the concept in the HL7 Access database repository. |
| Status | status | http://hl7.org/fhir/concept-properties#status | code | Designation of a concept's state. Normally is not populated unless the state is retired. |

| 1 | A | ASAP | As soon as possible, next highest priority after stat. | 16868, 16868 | active, active | 16868, 16868 | active, active |
| 1 | CR | callback results | Filler should contact the placer as soon as results are available, even for preliminary results. (Was "C" in HL7 version 2.3's reporting priority.) | 16876, 16876 | active, active | 16876, 16876 | active, active |
| 1 | CS | callback for scheduling | Filler should contact the placer (or target) to schedule the service. (Was "C" in HL7 version 2.3's TQ-priority component.) | 16871, 16871 | active, active | 16871, 16871 | active, active |
| 2 | CSP | callback placer for scheduling | Filler should contact the placer to schedule the service. (Was "C" in HL7 version 2.3's TQ-priority component.) | 16872 | active | 16872 | active |
| 2 | CSR | contact recipient for scheduling | Filler should contact the service recipient (target) to schedule the service. (Was "C" in HL7 version 2.3's TQ-priority component.) | 16873 | active | 16873 | active |

| 1 | EL | elective | Beneficial to the patient but not essential for survival. | 12239, 12239 | active, active | 12239, 12239 | active, active |
| 1 | EM | emergency | An unforeseen combination of circumstances or the resulting state that calls for immediate action. | 12241, 12241 | active, active | 12241, 12241 | active, active |
| 1 | P | preop | Used to indicate that a service is to be performed prior to a scheduled surgery. When ordering a service and using the pre-op priority, a check is done to see the amount of time that must be allowed for performance of the service. When the order is placed, a message can be generated indicating the time needed for the service so that it is not ordered in conflict with a scheduled operation. | 16870, 16870 | active, active | 16870, 16870 | active, active |
| 1 | PRN | as needed | An "as needed" order should be accompanied by a description of what constitutes a need. This description is represented by an observation service predicate as a precondition. | 16875, 16875 | active, active | 16875, 16875 | active, active |
| 1 | R | routine | Routine service, do at usual work hours. | 16869, 16869 | active, active | 16869, 16869 | active, active |
