fallback entries: Other and Accessories

The Special Dressings branch runs 3 levels deep. 19 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 67 codes marked terminal.

9 terminal codes are “- Other” entries, 13% 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 M0404 (Dressings for Wounds, Sores and Ulcerations), holding 28 of the 67 terminal codes.
