Unique Device Identification - Three Steps to Compliance

09 June 2014

Medical Design Technology features an article written by TEKLYNX Enterprise Product Manager, Nick Recht, discussing three steps to comply to Unique Device Identification (UDI). 


In the medical device industry, accurate identification has never been more important. Failure to adhere to rules and regulations can be the difference between life and death for patients. Growing concerns about product recalls, counterfeit devices and patient safety are leading to changing trends and increased regulations.

Differing descriptions of medical/surgical products and conflicting data has created problems within the U.S. healthcare industry supply chain. Unverifiable product data is being spread from organization to organization, which has led to challenges around product recalls, storing expired inventory, shipping incorrect products and more serious problems – all of which are preventable.

In effort to increase patient safety, reduce costs and improve efficiencies, the Food and Drug Administration (FDA) released a final rule on September 24, 2013, requiring that medical devices distributed in the United States be documented and tracked by a Unique Device Identifier, or UDI.


With the first compliance date rapidly approaching, now is the time to move from learning about the regulation to taking action and implementing key components to meet the requirements.

In order to comply with the UDI legislation, manufacturers must assign a UDI-compliant code to their product, use labeling software to label the products with the UDI and publish the data to the Global Unique Device Identification Database (GUDID), which will include a standard set of basic identifying elements for each device with a UDI.

Here are three steps to take to ensure compliance: 

  1. Create and Assign the UDI

    What, exactly, is a UDI? A Unique Device Identifier (UDI) is a system used to mark and identify medical devices within the healthcare supply chain, comprising a unique numeric or alphanumeric code with two parts:
    • A Device Identifier (DI), which identifies the labeler and the specific version or model of a device; and
    • A Production Identifier (PI), which identifies the lot/batch number, serial number, manufacture date, expiration date and/or a distinct identification code. 

  2. Choose the Right Labeling Software to Label the Products with the UDI

    Each medical device must now include a UDI, except where the rule provides for an exception or alternative placement. The UDI should be on the label of the device, provided in a human readable format and in a form that uses automatic identification and data capture (AIDC) technology.

    When choosing label design software, be sure that the application provides 21 CFR Part 11 compliant technologies, as medical device manufacturers are required to implement controls, including system validations, electronic signatures and documentation for software and systems involved in processing electronic data that are required to be maintained by the predicate rules or submitted to the FDA. A predicate rule is an underlying requirement, other than part 11, that was set forth in the Act, PHS Act and FDA regulations.

    It is also important to choose a label design software that is capable of printing the GS1 and Health Industry Bar Code (HIBC) and generate the AIDC technology for placing a UDI on labels for medical devices. “Ease of use and efficiency in generating labels that can meet GS1 barcode standards – like the requirements of UDI – are a vital consideration when choosing a label design software,” said David Kane, Label Design Product Manager of TEKLYNX Americas. “When choosing a labeling software, closely review the features to ensure that you can easily and efficiently meet UDI requirements.”

    Label stock is also an important component of compliance. Thermal transfer labels are a great way to mark the UDI on the device. They are cost effective and feature high resolution printing capabilities for barcodes, graphics and text. The finished label is high contrast for easy scanning, and the labels themselves are made of durable materials.

    Above is a fictitious example of  UDI on a medical device label made with TEKLYNX’ CODESOFT software. The label contains information about the product name, its expiration date, reference and lot numbers, manufacturer information, bar code and other product details.

  3. Submit and Store the UDI in the GUDID

    Manufacturers will be responsible for submitting and maintaining their own data in the GUDID. Labelers can access the Global Unique Device Identification Database (GUDID) - Draft Guidance for Industry to help prepare to submit information to the GUDID by describing key GUDID concepts such as accounts, user roles, the device identifier record life cycle, package configurations and the GUDID data attributes and descriptions. 

    The labeler must submit specific information about the device, including the UDI number, for review and approval to the GUDID and maintain accessibility of their UDI in the UDI database, unless subject to an exception or alternative. 
The first compliance date is effective on September 24, 2014, one year after publication of the final rule, when all labels and packages of Class III medical devices, which usually sustain or support life and/or are implanted, such as a pacemaker, and devices licensed under the Public Health Service Act (PHS) Act (for example, donor screening assays) must bear a UDI. Noncompliant companies can be banned from cross-state selling. By September of 2020, Class I devices, such as elastic bandages, must bear UDI on the device itself if it is intended to be used more than once and reprocessed before each use. 

Implementing this legislation will increase patient safety by:

  • Helping the FDA quickly isolate and correct product problems.
  • Optimizing patient care by requiring that devices are identifiable and secure throughout a secure global distribution chain to help address counterfeiting and diversion and prepare for medical emergencies.
  • Ensuring that product data is captured to populate electronic health records.
  • Creating more accurate reports of adverse events.
  • Leading to the development of a medical device ID system recognized worldwide.7
  • Enhancing analysis with a clear, standard way to document devices’ use in electronic health records, clinical information systems, claims databases, and registries.7
  • Enhancing analysis of devices on the market.
  • Utilizing a standardized product identifier for more effective management of device recalls.
  • Reducing medical errors due to improved device identification information. 
As rules and regulations are finalized and compliance dates approach, it is important to become familiar with the details of the UDI legislation and how to achieve compliance. "Medical device labeling will be vital for success of the legislation, and in improving patient safety," said Kane. "By changing the way you label products, you can minimize costs and increase efficiencies throughout your organization and the industry supply chain." It is best to get started now to implement a plan to reach UDI compliance by the mandated deadline, and realize long-term benefits from being able to do business with your customers in a different, better way.
