EMDN J04: Implantable Pumps
Complete hierarchy for EMDN group J04 in category J (Active-Implantable Devices): 9 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 J04 is structured
The Implantable Pumps branch runs 2 levels deep. One entry below is a branch heading that groups other codes rather than naming a device, so a classification has to resolve all the way down to one of the 9 codes marked terminal.
1 terminal code is an “- Other” entry and 2 are “- Accessories” entries, 33% 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.
Frequently asked questions
- Which J04 codes can be used in a EUDAMED device record?
- 9 of the 10 codes listed under J04 (Implantable Pumps) are terminal and can be selected. The other 1 is a branch heading that cannot.
- How deep is the J04 hierarchy?
- The J04 branch runs 2 levels below the group code.
- How many J04 codes are catch-all entries?
- 1 terminal code under J04 is an "- Other" entry and 2 are "- Accessories" entries, 33% of the branch. The remaining 6 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.
