fallback entries: Other and Accessories

The Devices for Urethral, Ureteral and Nephrostomic Dilation branch runs 3 levels deep. 4 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 8 codes marked terminal.

2 terminal codes are “- Other” entries and 1 is an “- Accessories” entry, 38% 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 U0301 (Devices for Rigid Dilation of the Urinary Tract), holding 4 of the 8 terminal codes.
