How N01 is structured
The Encephalic and Peripheral Nervous System Devices branch runs 4 levels deep. 10 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 36 codes marked terminal.
11 terminal codes are “- Other” entries and 2 are “- Accessories” entries, 36% 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 N0101 (Neurophysiology Devices), holding 10 of the 36 terminal codes.
Frequently asked questions
- Which N01 codes can be used in a EUDAMED device record?
- 36 of the 46 codes listed under N01 (Encephalic and Peripheral Nervous System Devices) are terminal and can be selected. The other 10 are branch headings that cannot.
- How deep is the N01 hierarchy?
- The N01 branch runs 4 levels below the group code. Its largest sub-branch is N0101 (Neurophysiology Devices), which holds 10 of the 36 terminal codes.
- How many N01 codes are catch-all entries?
- 11 terminal codes under N01 are "- Other" entries and 2 are "- Accessories" entries, 36% of the branch. The remaining 23 name a specific device type.
