EMDN A01: Needles

Complete hierarchy for EMDN group A01 in category A (Devices for Administration, Withdrawal and Collection): 82 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 A01 is structured

terminal codes, selectable in a device record

branch headings, not selectable

name a specific device type

20%

fallback entries: Other and Accessories

The Needles branch runs 4 levels deep. 23 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 82 codes marked terminal.

15 terminal codes are “- Other” entries and 1 is an “- Accessories” entry, 20% 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 A0102 (Biopsy Needles and Kits), holding 21 of the 82 terminal codes.

Frequently asked questions

Which A01 codes can be used in a EUDAMED device record?: 82 of the 105 codes listed under A01 (Needles) are terminal and can be selected. The other 23 are branch headings that cannot.
How deep is the A01 hierarchy?: The A01 branch runs 4 levels below the group code. Its largest sub-branch is A0102 (Biopsy Needles and Kits), which holds 21 of the 82 terminal codes.
How many A01 codes are catch-all entries?: 15 terminal codes under A01 are "- Other" entries and 1 is an "- Accessories" entry, 20% of the branch. The remaining 66 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.
