EMDN Q03: ENT Devices
Complete hierarchy for EMDN group Q03 in category Q (Dental, Ophthalmologic and ENT Devices): 32 terminal codes, EMDN v2026. Terminal codes are the ones accepted in a EUDAMED device record.
Registered classes, as of 8 Sep 2026. For each code with at least 20 registrations under a legislation, the chip shows how devices registered in EUDAMED under that code are classed, counted once per primary UDI-DI and kept separate for each legislation. It is not a determination. The class of a device comes from the MDR and IVDR classification rules for its intended purpose. MDD and IVDD classes are the directive classification and can differ from the class the same device would have under MDR or IVDR.

How Q03 is structured
The ENT Devices branch runs 3 levels deep. 8 entries below are branch headings that group other codes rather than naming a device, so a classification has to resolve all the way down to one of the 32 codes marked terminal.
9 terminal codes are “- Other” entries, 28% of the branch. An “- Other” code is the residual slot for devices its siblings do not name, so it is worth ruling out every specific sibling before settling on one.
The largest sub-branch is Q0303 (ENT Surgery Instruments, Single-Use), holding 17 of the 32 terminal codes.
Frequently asked questions
- Which Q03 codes can be used in a EUDAMED device record?
- 32 of the 40 codes listed under Q03 (ENT Devices) are terminal and can be selected. The other 8 are branch headings that cannot.
- How deep is the Q03 hierarchy?
- The Q03 branch runs 3 levels below the group code. Its largest sub-branch is Q0303 (ENT Surgery Instruments, Single-Use), which holds 17 of the 32 terminal codes.
- How many Q03 codes are catch-all entries?
- 9 terminal codes under Q03 are "- Other" entries, 28% of the branch. The remaining 23 name a specific device type.
Not sure which level to stop at, or which of two plausible codes to submit? The guide to choosing an EMDN code walks the decision level by level, with a worked example and the mistakes that get a EUDAMED registration rejected.
