The 3 groups in this category are not evenly sized. N01 (Encephalic and Peripheral Nervous System Devices) alone holds 36 terminal codes, 55% of the category, while 1 group is a single terminal code with no hierarchy at all. Hierarchies here run up to 4 levels below a group code, and 37% of the category’s terminal codes are “- Other” or “- Accessories” fallbacks rather than named device types.
Frequently asked questions
- How many codes are in EMDN category N?
- Category N (Nervous and Medullary Systems Devices) holds 65 terminal codes spread across 3 groups. Terminal codes are the ones a EUDAMED device record accepts. EMDN v2026.
- Which N group has the most codes?
- N01 (Encephalic and Peripheral Nervous System Devices), with 36 terminal codes, or 55% of everything in category N. At the other end, 1 group is a single terminal code with no hierarchy below it.
- How much of category N is catch-all codes?
- 24 of the 65 terminal codes in category N are "- Other" or "- Accessories" entries, 37% of the category. Those are residual slots for devices the named codes do not cover, so it is worth ruling out the specific codes in a group before settling on one.
