Which R02 codes can be used in a EUDAMED device record?

22 of the 28 codes listed under R02 (Breathing Circuits and Catheter Mounts) are terminal and can be selected. The other 6 are branch headings that cannot.

How deep is the R02 hierarchy?

The R02 branch runs 3 levels below the group code. Its largest sub-branch is R0201 (Respiratory Circuits and Kits), which holds 12 of the 22 terminal codes.

How many R02 codes are catch-all entries?

5 terminal codes under R02 are "- Other" entries, 23% of the branch. The remaining 17 name a specific device type.

EMDN R02: Breathing Circuits and Catheter Mounts

Complete hierarchy for EMDN group R02 in category R (Respiratory and Anaesthesia Devices): 22 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 R02 is structured

terminal codes, selectable in a device record

branch headings, not selectable

name a specific device type

23%

fallback entries: Other and Accessories

The Breathing Circuits and Catheter Mounts branch runs 3 levels deep. 6 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 22 codes marked terminal.

5 terminal codes are “- Other” entries, 23% 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 R0201 (Respiratory Circuits and Kits), holding 12 of the 22 terminal codes.
