Section 10.29.1

10.29.1 Unique Device Identifier

The UDI is a combination of the Device Identifier and the Production Identifier.

The format of the string is defined by a corresponding Issuing Agency, such as:

Details for encoding a valid device identifier are managed by the Issuing Agency. For full documentation, refer to issuer materials.

The United States FDA requires the Issuing Agency to use only characters and numbers from the invariant character set of ISO/IEC 646 (ISO 7-bit coded character set also known as ISO IR 6). DICOM puts no constraints on the length of the string or the character sets beyond the UT Value Representation. Implementations should be prepared to handle very large strings and unusual characters.
