Periodontal Maintenance - CDT Code Guide

Periodontics/Other Periodontal Services

Overview

CDT code D4910 refers to periodontal maintenance, a critical procedure for patients who have undergone periodontal therapy. This maintenance is essential for managing periodontal health and is performed at intervals determined by the dentist based on clinical evaluations. The procedure involves the removal of bacterial plaque and calculus from both above and below the gum line, as well as site-specific scaling and root planing when necessary. Additionally, teeth polishing is included to maintain oral health. If new or recurring periodontal disease is detected, further diagnostic and treatment measures may be required. This procedure is vital for preserving the health of the dentition or any implant replacements over the patient's lifetime.

When to Use This Code

After completion of active periodontal therapy to maintain periodontal health.
For patients with a history of periodontal disease requiring ongoing maintenance.
When clinical evaluation indicates the need for removal of plaque and calculus.
In cases where site-specific scaling and root planing are necessary.
To prevent the recurrence of periodontal disease in patients with implants.

Documentation Requirements

Detailed clinical notes on the patient's periodontal status.
Documentation of previous periodontal therapy and maintenance schedule.
Records of plaque and calculus removal, including specific sites treated.
Evidence of clinical evaluation determining the need for maintenance.
Notes on any additional diagnostic or treatment procedures if new disease is detected.

Billing Considerations

Periodontal maintenance under code D4910 is typically covered at regular intervals, often every three to four months, depending on the patient's insurance plan. It's important to verify the frequency limitations with the patient's insurance provider. Common modifiers may include those indicating the presence of implants or specific site treatments. Ensure accurate documentation to support the necessity of the procedure for insurance claims.
