EMDN G01: Oro-Oesophageal Tubes

Complete hierarchy for EMDN group G01 in category G (Gastrointestinal Devices): 14 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 G01 is structured

14
terminal codes, selectable in a device record
3
branch headings, not selectable
9
name a specific device type
36%
fallback entries: Other and Accessories

The Oro-Oesophageal Tubes branch runs 2 levels deep. 3 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 14 codes marked terminal.

4 terminal codes are “- Other” entries and 1 is an “- Accessories” entry, 36% 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 G0103 (Oro-Oesophageal Diagnostic Tubes), holding 6 of the 14 terminal codes.

Frequently asked questions

Which G01 codes can be used in a EUDAMED device record?
14 of the 17 codes listed under G01 (Oro-Oesophageal Tubes) are terminal and can be selected. The other 3 are branch headings that cannot.
How deep is the G01 hierarchy?
The G01 branch runs 2 levels below the group code. Its largest sub-branch is G0103 (Oro-Oesophageal Diagnostic Tubes), which holds 6 of the 14 terminal codes.
How many G01 codes are catch-all entries?
4 terminal codes under G01 are "- Other" entries and 1 is an "- Accessories" entry, 36% of the branch. The remaining 9 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.
