D4910 Dental Code
D4910 Dental Code is the dental procedure for Periodontal Maintenance – Limited To 1 Treatment Each 6 Month Period.
The D4910 Dental Code refers specifically to Periodontal Maintenance, a critical post-therapy service used in the management and long-term care of patients with periodontal disease. This CDT code is designated for routine periodontal cleanings and evaluations, and it is typically limited to one treatment every six-month period, as determined by most dental insurance plans and clinical guidelines.
The D4910 procedure is performed following active periodontal therapy, such as scaling and root planing (SRP), and includes the removal of bacterial plaque and calculus from above and below the gumline. It also includes site-specific scaling and root planing when indicated, as well as polishing the teeth and an oral evaluation. The purpose of the D4910 code is to maintain gum health and prevent the recurrence of periodontal infections or disease progression.
When using the D4910 CDT Code for your dental procedure billing, it is essential to ensure that it accurately reflects the services provided to the patient. Dental professionals must verify the patient’s treatment history and clinical necessity before selecting this code. It is also highly recommended to review alternative CDT codes that may better match the nature of the service delivered. For example, standard prophylaxis (D1110), full mouth debridement (D4355), or periodontal scaling and root planing codes (D4341, D4342) may be more appropriate depending on the patient’s condition and treatment status.
Accurate CDT coding for dental billing is crucial for proper claim processing, insurance coverage, and patient care continuity. Misusing D4910 in situations where other codes are more applicable could lead to denied claims or compliance issues. Always consult updated CDT code books or official ADA guidelines to ensure the correct use of D4910 or any other CDT dental codes.
D4910 Dental Code Definition
What is D4910 Dental Code?
The D4910 Dental Code is officially designated for Periodontal Maintenance, a critical dental procedure that plays a key role in ongoing oral health care. This procedure is specifically performed after a patient has received comprehensive periodontal treatment and is entering the maintenance phase of care to help prevent further progression of gum disease.
So, what does the D4910 code mean? The D4910 code refers to a professional dental service provided to maintain periodontal health. This service typically includes a detailed cleaning that involves the removal of plaque, calculus (tartar), and stains from the surfaces of the teeth above and below the gumline. In addition, it often includes thorough gum evaluations and monitoring of periodontal pocket depths to help detect signs of recurring disease. This procedure is considered essential for patients with a history of periodontal disease and is limited to one treatment every six-month period, unless medically necessary for more frequent visits and appropriately documented.
This maintenance visit is not just a standard cleaning—it is a targeted periodontal treatment focused on keeping the gums and bone supporting the teeth in optimal condition. It aims to stop the return of harmful bacteria and inflammation that could otherwise lead to further complications such as tooth loss or infection. For patients who have undergone periodontal therapy, maintaining a strict schedule of maintenance appointments coded under D4910 is vital to long-term dental health and stability.
Using the D4910 code correctly in dental procedure billing ensures that the treatment is categorized accurately and that the patient receives the periodontal support they require. Since this code is tied directly to continued periodontal care, it is important for both dental professionals and billing personnel to fully understand its purpose, frequency limits, and procedural scope.

What are CDT Codes (Current Dental Terminology)?
CDT Codes, short for Current Dental Terminology, are a standardized set of dental procedure codes used across the dental industry for documentation, billing, and insurance claim processing. These codes are maintained and published by the American Dental Association (ADA) and are updated annually to reflect changes in clinical practices, technological advancements, and billing requirements.
The D4910 Dental Code is one of many CDT codes used to represent specific dental procedures—in this case, Periodontal Maintenance. Each code within the CDT system is a five-character alphanumeric identifier (e.g., D4910) that corresponds to a detailed description of a dental service. These codes are universally recognized by dental professionals, insurance carriers, public health programs, and third-party administrators, making them an essential part of modern dental practice management.
CDT codes are designed to:
- Provide accurate documentation of dental services performed
- Streamline communication between dental offices and insurance companies
- Facilitate efficient claim processing and payment
- Ensure compliance with federal and state regulations in dental billing
Understanding how to properly use CDT codes like D4910 is crucial for avoiding claim denials, billing errors, and compliance issues. Dentists and office staff must stay updated on annual code revisions, ADA updates, and any procedural edits that may impact how certain treatments should be reported.

Knowing how this code fits into the broader CDT framework empowers dental professionals to provide accurate treatment records and secure appropriate reimbursement for the care they deliver.
