D1120 — Child cleaning (prophylaxis)
D1120 is the routine cleaning for a child, priced lower because there are fewer and smaller teeth to clean.
two codes describe prophylaxis (cleaning), and this is one of them. What separates it from the other one is the subject of this page; the prophylaxis (cleaning) guide covers the treatment itself.
What follows is the detail behind the number: the conditions the code sets, its typical fee, its usual benefit treatment, and a code-by-code comparison with its closest neighbours.
D1120 against the codes beside it
D1110 — Adult cleaning (prophylaxis): It is the same procedure with one word changed: adult rather than child.
That code and D1120 are the whole group — nothing else in the code set describes this procedure. These distinctions exist because they change what was actually done. A claim for D1120 when the record describes one of the others is not a technicality — it is the difference between a paid claim and a returned one.
Every code in this group
These codes describe the same broad procedure and differ in one respect each. Each has its own page with its own fee range and coverage notes.
