36%

fallback entries: Other and Accessories

The Oro-Oesophageal Tubes 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 14 codes marked terminal.

4 terminal codes are “- Other” entries and 1 is an “- Accessories” entry, 36% 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 G0103 (Oro-Oesophageal Diagnostic Tubes), holding 6 of the 14 terminal codes.
