What D4910 means

D4910 covers periodontal maintenance, the recurring cleaning provided after a patient has had active periodontal therapy such as scaling and root planing or gum surgery. "D" is dental, "49" is the periodontal maintenance group, and "10" is this code. It includes removing plaque and tartar above and below the gumline, site-specific scaling and root planing where needed, and polishing.

The purpose is to keep periodontal disease from coming back. Once someone has been treated for gum disease, their maintenance schedule is set by the dentist based on how their gums respond, and it continues indefinitely rather than ending after a set number of visits.

The important distinction is D4910 versus a routine cleaning (D1110). A routine prophylaxis is for healthy mouths; periodontal maintenance is for patients with a history of treated gum disease and is therapeutic in nature. Mixing the two up, or alternating them incorrectly, is a frequent billing problem.

When it's typically used

D4910 is reported for patients who have completed active periodontal treatment and now need ongoing maintenance cleanings to keep the disease stable. Intervals (often every three to four months) are set by the dentist based on the patient's condition.

How much does D4910 cost?

Periodontal maintenance typically costs more than a routine cleaning, often roughly 100 to 300 USD per visit depending on region and office, reflecting the deeper, more involved care.

Is D4910 covered by insurance?

Coverage varies; some plans cover D4910 at a similar level to cleanings but limit the total number of perio-maintenance and routine cleanings per year combined. It generally can't be billed on the same day as SRP or a routine prophylaxis, and a history of periodontal treatment supports the claim.

Frequently asked questions

What is the D4910 dental code?

It's periodontal maintenance — the ongoing cleaning after active gum disease treatment, more involved than a routine cleaning and continued at regular intervals long-term.

What's the difference between D4910 and a regular cleaning?

A routine cleaning (D1110) is preventive for healthy mouths. D4910 is therapeutic maintenance for patients with a history of treated gum disease, including below-the-gumline care.

How often is periodontal maintenance done?

Often every three to four months, but the interval is set by the dentist based on how the patient's gums respond. It continues for the life of the teeth.

How much does D4910 cost?

Often around 100 to 300 USD per visit depending on location and office, typically more than a routine cleaning.

Does insurance cover D4910?

Often yes, but plans may cap the combined number of maintenance and routine cleanings per year. It usually can't be billed the same day as SRP or a routine cleaning.

Can I switch back to regular cleanings after perio maintenance?

That's a clinical decision for your dentist based on your gum health. Many periodontal patients stay on maintenance long-term to keep the disease stable.
