How J04 is structured

terminal codes, selectable in a device record

branch heading, not selectable

name a specific device type

33%

fallback entries: Other and Accessories

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.
