| Data Element Information | |
| Rationale for Separate Consideration | The UDI is a string of characters with no meaning. The UDI is composed of separate meaningful parts that should be parsed from the UDI and stored separately in a patient’s health record because each contribute to the identify of a regulated medical device. The UDI may be stored as a string to verify the human readable interpretation of the machine readable format of UDI on a device label. However, the UDI-DI and each part of the UDI-PI should also be stored in separate fields. The UDI-DI is the main (primary) lookup for a medical device and meets the requirements to uniquely identify a device through its distribution and use. |
| Use Case Description(s) | |
| Use Case Description | Referring to the UDI in USCDI without specifying the separate parts of the UDI has introduced unnecessary confusion for device users that are scanning the UDI. The use of UDI as a full string for documenting UDI is only necessary for data validation, not to add meaning for tracking a device and associating that device with a patient. The UDI-DI and each part of the UDI-PI (lot, serial, expiration date, manufacturing date, and donation identification number) are the values that should be stored and exchanged separately in Health IT systems. The UDI-DI is used as a field in adverse event reporting, recalls, claims, materials management and inventory control to track the device at the model version level. These use cases are currently being documented in the HL7 UDI Implementation Guidance Requirements document. The document was first balloted in September 2020 and is expected to be published by the end of the year. |
| Estimated number of stakeholders capturing, accessing using or exchanging | Every stakeholder that would capture access, use or exchange the UDI would more appropriately capture, access, use or exchange the UDI-DI and parts of the UDI-PI. |

| Estimated number of stakeholders capturing, accessing using or exchanging | It is estimated that approximately 200 million people would use, be exposed to or derive better data to make decisions about implantable devices after the UDI were separated into discrete fields. This estimate is based upon the following approximations and assumptions that would also be be more accurate if the UDI were split into UDI-DI and UDI-PI and all of this data were available in health records. Approximately 12 million implant procedures performed in the US per year. An average implant life of 10 years 100 million people in the US with at least one implant – 20% estimated to have multiple implants – this is equivalent to 1/3 of US population over 50 years old Average US household of 2-3 people with estimate that at least one other person besides the person with the implant cares about the implant Approximation - 200 million people would benefit from having UDI or know someone they care about with an implanted device and would benefit from the information. |

| Potential Challenges | |
| Restrictions on Standardization (e.g. proprietary code) | The UDI-DI and UDI-PI currently exist in human and machine readable format on the label of devices. The UDI-DI are publicly available in AccessGUDID. There are no restriction on the use of this data. |
| Restrictions on Use (e.g. licensing, user fees) | No restrictions |
| Privacy and Security Concerns | The UDI-DI can be part of a limited or de-identified data set. See https://www.hhs.gov/hipaa/for-professionals/faq/2071/can-device-identifier-di-portion-unique-device-identifier-udi-be-part-limited-or-de-identified/index.html The fact that UDI-DI must be separate from the remainder of the UDI to qualify as a limited data set provides more rationale for UDI-DI to be stored separately in HIT. |
| Estimate of Overall Burden | To effectively implement UDI in healthcare a system should be storing each of the UDI parts separately. If the system is not, it is adding unecessary burden to the UDI adoption process. |

Information from the submission form |

| UDI-Device Identifier or UDI-DI |
Description
The DI portion of the UDI placed on the lowest package level of a device that is required to meet UDI label requirements. If the device is not packaged, the UDI may be on the device itself, thereby satisfying both the UDI label and the direct mark (DM) requirement if the UDI is intended to be permanent. The primary DI is the main (primary) lookup for a medical device and meets the requirements to uniquely identify a device through its distribution and use.
