EMDN M01: Cotton and Synthetic Wadding

Complete hierarchy for EMDN group M01 in category M (Devices for General and Specialist Dressings): 10 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 M01 is structured

10
terminal codes, selectable in a device record
3
branch headings, not selectable
7
name a specific device type
30%
fallback entries: Other and Accessories

The Cotton and Synthetic Wadding branch runs 3 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 10 codes marked terminal.

3 terminal codes are “- Other” entries, 30% 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 M0102 (Orthopaedic Wadding), holding 5 of the 10 terminal codes.

Frequently asked questions

Which M01 codes can be used in a EUDAMED device record?
10 of the 13 codes listed under M01 (Cotton and Synthetic Wadding) are terminal and can be selected. The other 3 are branch headings that cannot.
How deep is the M01 hierarchy?
The M01 branch runs 3 levels below the group code. Its largest sub-branch is M0102 (Orthopaedic Wadding), which holds 5 of the 10 terminal codes.
How many M01 codes are catch-all entries?
3 terminal codes under M01 are "- Other" entries, 30% of the branch. The remaining 7 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.
