Which M02 codes can be used in a EUDAMED device record?

40 of the 65 codes listed under M02 (Gauzes) are terminal and can be selected. The other 25 are branch headings that cannot.

How deep is the M02 hierarchy?

The M02 branch runs 4 levels below the group code. Its largest sub-branch is M0201 (Cotton Gauzes), which holds 20 of the 40 terminal codes.

How many M02 codes are catch-all entries?

4 terminal codes under M02 are "- Other" entries, 10% of the branch. The remaining 36 name a specific device type.

EMDN M02: Gauzes

Complete hierarchy for EMDN group M02 in category M (Devices for General and Specialist Dressings): 40 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.

  Registered in EUDAMED under MDD with this code, the 33 devices are split across classes (as of 8 Sep 2026).

  Counted once per primary UDI-DI, using the class on the registration. The class of a device comes from the MDR and IVDR classification rules for its intended purpose, so a code is evidence of how others registered, not a determination. MDD and IVDD classes are the directive classification and can differ under MDR or IVDR.

10%

fallback entries: Other and Accessories

The Gauzes branch runs 4 levels deep. 25 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 40 codes marked terminal.

4 terminal codes are “- Other” entries, 10% 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 M0201 (Cotton Gauzes), holding 20 of the 40 terminal codes.

Frequently asked questions

Which M02 codes can be used in a EUDAMED device record?: 40 of the 65 codes listed under M02 (Gauzes) are terminal and can be selected. The other 25 are branch headings that cannot.
How deep is the M02 hierarchy?: The M02 branch runs 4 levels below the group code. Its largest sub-branch is M0201 (Cotton Gauzes), which holds 20 of the 40 terminal codes.
How many M02 codes are catch-all entries?: 4 terminal codes under M02 are "- Other" entries, 10% of the branch. The remaining 36 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.
