PHC Hub uses three tiers to gauge the usefulness of a value in making an exact patient match.
PHC Hub always first attempts to identify a patient using values sent in QRD-8.1. The values submitted in this field can be used to uniquely identify a patient independently of other submitted values. It is recommended to use these values to identify a patient if they are available.
Typical values used in QRD-8.1 are:
| SEQ | LEN | DT | OPT | RP/# | TBL# | ITEM# | Element Name |
| 8 | 60 | XCN | R | Y | 00032 | Who Subject Filter |
Source: Table 2.24.4: Original - Style Query Definition Segment, from the HL7 Version 2.3.1 Final Standard 05/1999, pp. 2-112.
| SEQ | LEN | DT | OPT | RP/# | TBL# | ITEM# | Element Name |
| 1 | ST | R | ID Number | ||||
| 13 | IS | R | Identifier Type Code |
Source: Table 2.8.49: XCN - Extended Composite ID Number and Name for Persons, from the HL7 Version 2.3.1 Final Standard 05/1999, pp. 2-112.
Example:
QRD||||||||123456789^^^^^^^^^^^^MR |
If the Tier 1 values are insufficient to determine a match, PHC Hub uses Tier 2 values to try to determine a match.

Should an exact match be made based on Tier 2 values alone, Tier 3 values are not considered. If Tier 2 results in the return of multiple patients, the following values are used to help filter the patients in the attempt to return a singular exact match:
| Location | Name | Comments |
| QRD-8.4 | Patient Middle | |
| QRF-5.1 | Patient SSN | |
| QRF-5.4 | Patient Birth File Number | |
| QRF-5.5 | Patient Medicaid Number | |
| QRF-5.7.1 | Mother's Maiden Name | This will search for the guardian last name, using the mother's maiden name. |
| QRF-5.11 | Patient Phone | |
| QRF-5.12.1 | Patient Address | |
| QRF-5.12.3 | Patient City | |
| QRF-5.12.4 | Patient State | |
| QRF-5.12.5 | Patient Zip |
