How C03 is structured

terminal codes, selectable in a device record

branch headings, not selectable

name a specific device type

32%

fallback entries: Other and Accessories

The Cardiac Surgery and Heart Transplant Devices branch runs 4 levels deep. 10 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 28 codes marked terminal.

7 terminal codes are “- Other” entries and 2 are “- Accessories” entries, 32% 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 C0301 (Extracorporeal Assisted Circulation Devices), holding 20 of the 28 terminal codes.
