Is a perio maintenance cleaning covered by insurance?
Usually yes, but not the way a regular cleaning is. Most plans pay periodontal maintenance (code D4910) as a basic service at 70 to 80%, so the patient owes a share at every recall where a routine cleaning was free. D4910 is the ongoing recall visit for anyone who has had deep cleaning or gum surgery, and plans only pay it when that history is on file.
70 to 80%
Basic, not the free cleaning
Not 100%
Most plans pay D4910 as basic. The patient who used to pay nothing now owes 20 to 30% at every recall, and the desk hears about it first.
Perio history
D4910 pays only after documented deep cleaning (D4341 or D4342) or gum surgery. No history on the plan's record means an automatic denial.
2 to 4 a year
The typical allowance, but it usually shares the plan's cleaning frequency. Two cleanings a year means two D4910 visits, not two plus two.
D1110 swap?
Alternating perio maintenance with a regular cleaning is allowed on some plans and denied on many. One check per patient tells the desk which, before the visit.

When D4910 is the right code
- Patient has deep cleaning or gum surgery on record
- The visit maintains that result, not new active disease
- Cleaning above and below the gumline with pocket checks
- Provider has set a perio recall interval for the patient
Documentation payers expect
The dates and codes of the prior periodontal treatment, updated periodontal charting at each visit, and the recall interval in the notes. If the treatment was done elsewhere, get that history into the record before billing.
Why perio maintenance gets denied
What happens after perio maintenance starts
Perio maintenance is not a one-time bill. It repeats two to four times a year, and on most plans each visit carries a 20 to 30% share where the old cleaning cost nothing. Add the exam (D0120) and bitewings (D0274) on their own schedules and the total changes every visit. When pockets come back, it is deep cleaning (D4341) and the cycle restarts. The desk that quotes each visit from the plan's real percentages, checked before the patient arrives, never has the 'this used to be free' talk.
D4910, quick answers
Does insurance cover periodontal maintenance?
Most plans cover D4910 as a basic service at 70 to 80%, which means the patient pays a share at each visit instead of getting a free cleaning.
Why is my cleaning not free anymore?
After a deep cleaning, recall is billed as periodontal maintenance (D4910), not a routine cleaning (D1110). Plans put D4910 in the basic class, so coinsurance applies.
How many perio maintenance visits will a plan pay for?
Typically two to four a year, but it usually shares the plan's overall cleaning frequency. Two cleanings a year often means two D4910 visits total.
Can we alternate D4910 with a regular cleaning?
It depends on the plan. Some allow it, many do not. Check the specific plan before the desk offers it as a way to save the patient money.
Does D4910 pay if the deep cleaning was done at another office?
Only if the payer has the history. Send the prior treatment dates and codes with the claim, or expect a denial for no periodontal history.
