How J01 is structured

55
terminal codes, selectable in a device record
21
branch headings, not selectable
38
name a specific device type
31%
fallback entries: Other and Accessories

The Cardiac Functionality Implantable Devices branch runs 5 levels deep. 21 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 55 codes marked terminal.

9 terminal codes are “- Other” entries and 8 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 J0190 (Implantable Cardiac Devices - Various), holding 21 of the 55 terminal codes.

Frequently asked questions

Which J01 codes can be used in a EUDAMED device record?
55 of the 76 codes listed under J01 (Cardiac Functionality Implantable Devices) are terminal and can be selected. The other 21 are branch headings that cannot.
How deep is the J01 hierarchy?
The J01 branch runs 5 levels below the group code. Its largest sub-branch is J0190 (Implantable Cardiac Devices - Various), which holds 21 of the 55 terminal codes.
How many J01 codes are catch-all entries?
9 terminal codes under J01 are "- Other" entries and 8 are "- Accessories" entries, 31% of the branch. The remaining 38 name a specific device type.
