EMDN J02: Implantable Neurostimulators

Complete hierarchy for EMDN group J02 in category J (Active-Implantable Devices): 35 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 J02 is structured

35
terminal codes, selectable in a device record
8
branch headings, not selectable
24
name a specific device type
31%
fallback entries: Other and Accessories

The Implantable Neurostimulators branch runs 3 levels deep. 8 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 35 codes marked terminal.

5 terminal codes are “- Other” entries and 6 are “- Accessories” entries, 31% 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 J0202 (Spinal Implantable Neurostimulators), holding 6 of the 35 terminal codes.

Frequently asked questions

Which J02 codes can be used in a EUDAMED device record?
35 of the 43 codes listed under J02 (Implantable Neurostimulators) are terminal and can be selected. The other 8 are branch headings that cannot.
How deep is the J02 hierarchy?
The J02 branch runs 3 levels below the group code. Its largest sub-branch is J0202 (Spinal Implantable Neurostimulators), which holds 6 of the 35 terminal codes.
How many J02 codes are catch-all entries?
5 terminal codes under J02 are "- Other" entries and 6 are "- Accessories" entries, 31% of the branch. The remaining 24 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.
