Is a gingivitis cleaning covered by insurance?
It depends on the plan, more than almost any other cleaning code. Some plans pay it as a basic service at 70 to 80%, some pay it at the regular cleaning rate, and some do not cover it at all. Code D4346 is the full-mouth therapeutic cleaning for swollen, bleeding gums when there is no bone loss: more than a routine cleaning, less than a deep cleaning.
Varies
Basic, prophy rate, or not covered
3 ways plans pay
As basic at 70 to 80%, at the 100% cleaning rate, or not at all. The same visit costs a patient nothing or most of the fee, plan by plan.
Uses a cleaning
On most plans D4346 counts against the two cleanings a year. Bill it in March and the patient's September prophy (D1110) can deny for frequency.
No bone loss
That is the line. Bleeding and swelling with healthy bone is D4346; bone loss on the X-ray moves it to a deep cleaning (D4341 or D4342).
Whole mouth
D4346 is one code for the full mouth, not per quadrant, so it cannot be split across visits. Check the plan first so the desk quotes one real number.
What would a real check show for this patient's D4346?
Pick a sample plan and type your fee. This is the visibility a real-time check gives the desk for every actual patient, in under a second.

When D4346 is the right code
- Swollen, bleeding gums across most of the mouth, not one spot
- No bone loss on current X-rays
- No deep pockets that would call for a deep cleaning
- More buildup and inflammation than a routine cleaning handles
Documentation payers expect
Periodontal charting showing the bleeding sites with no bone loss, current X-rays, and a note explaining why a routine cleaning was not enough. Photos help on plans that review this code.
Why gingivitis cleanings get denied
What happens after the gingivitis cleaning
The follow-up is usually a routine cleaning (D1110) once the gums calm down, and that is where the frequency trap bites: on most plans D4346 used one of the year's two cleanings, so the next prophy may be out of pocket. If the inflammation does not settle, the next step is often a perio exam (D0180) and possibly deep cleaning (D4341), which moves recall to D4910. Each of those has a different number on the plan; knowing them before the first visit is what saves the patient three surprise bills.
D4346, quick answers
Does insurance cover a gingivitis cleaning?
It depends on the plan. Some pay D4346 as a basic service at 70 to 80%, some pay it like a regular cleaning at 100%, and some do not cover it at all.
Why is D4346 covered so differently from plan to plan?
It is a newer code that sits between a routine cleaning and a deep cleaning, and plans map it to their benefit tables in different ways. Only a check of that specific plan tells you which.
Does D4346 use up one of my two cleanings?
On most plans, yes. It usually counts against the cleaning frequency, so a routine cleaning later in the year may not be covered.
Can the desk bill D4346 with a regular cleaning on the same day?
No. D4346 replaces the routine cleaning for that visit. Plans deny the pair.
What makes it D4346 instead of a deep cleaning?
Bone loss. Inflamed, bleeding gums with healthy bone on the X-ray is D4346; bone loss and deep pockets move it to D4341 or D4342.
