How U04 is structured

12
terminal codes, selectable in a device record
3
branch headings, not selectable
7
name a specific device type
42%
fallback entries: Other and Accessories

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.
