How U04 is structured
The Devices for Percutaneous Urinary Drainage and Nephrostomy Catheters branch runs 2 levels deep. 3 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 12 codes marked terminal.
4 terminal codes are “- Other” entries and 1 is an “- Accessories” entry, 42% 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 U0402 (Devices for Percutaneous Nephrostomy), holding 4 of the 12 terminal codes.
Frequently asked questions
- Which U04 codes can be used in a EUDAMED device record?
- 12 of the 15 codes listed under U04 (Devices for Percutaneous Urinary Drainage and Nephrostomy Catheters) are terminal and can be selected. The other 3 are branch headings that cannot.
