Understanding the D7670 Dental Code: A Comprehensive Guide for Patients and Practitioners

Dental billing codes can be complex, but understanding them is crucial for both dental professionals and patients. One such code, D7670, plays a significant role in periodontal treatments. Whether you’re a dentist looking to ensure accurate billing or a patient trying to decipher your treatment plan, this guide will provide an in-depth look at the D7670 dental code, its applications, and its importance in modern dentistry.

This article will explore:

• The definition and purpose of D7670

• When and why this code is used

• How it differs from other periodontal codes

• Insurance implications and reimbursement factors

• Best practices for dental professionals

By the end, you’ll have a clear understanding of D7670 and its role in dental care.

2. What is the D7670 Dental Code?

The D7670 code is classified under the American Dental Association (ADA) Current Dental Terminology (CDT) as:

“D7670 – Selective Polishing – This is the removal of plaque and/or stain from designated teeth only, performed at the same appointment as a prophylaxis.”

Unlike a full-mouth prophylaxis (D1110), D7670 is used when only specific teeth require stain or plaque removal, rather than the entire dentition.

Key Features of D7670:

• Limited to selected teeth (not a full-mouth treatment)

• Performed alongside a regular cleaning (prophylaxis)

• Focuses on aesthetic or localized stain removal

3. When is the D7670 Code Used?

Dentists use D7670 in specific scenarios, including:

✅ Localized Staining – When only a few teeth have stains (e.g., from smoking, coffee, or tartar buildup).
✅ Cosmetic Requests – If a patient wants selective polishing before an event (e.g., wedding photos).
✅ Post-Orthodontic Care – Removing stains around brackets after braces removal.
✅ Partial Denture or Crown Areas – Cleaning around prosthetic devices without a full-mouth polish.

When NOT to Use D7670:

❌ Full-mouth prophylaxis (Use D1110 instead)
❌ Scaling and root planing (Use D4341-D4342)
❌ Periodontal maintenance (Use D4910)

4. Key Components of the D7670 Procedure

The D7670 procedure involves:

1. Assessment – Identifying which teeth need polishing.

2. Prophylaxis (Cleaning) – A standard cleaning (D1110) is performed first.

3. Selective Polishing – Only the stained or plaque-heavy teeth are polished.

4. Documentation – Accurate records must be kept to justify billing.

Tools Used in D7670:

• Prophy cup & paste (for polishing)

• Air-polishing devices (for tougher stains)

• Ultrasonic scalers (if light debridement is needed)

5. Differences Between D7670 and Similar Codes

6. Insurance and Reimbursement Considerations

• Coverage Varies – Some insurers consider D7670 a cosmetic add-on and may not cover it.

• Bundling Rules – Often, D7670 is bundled with D1110, meaning separate reimbursement may not apply.

• Documentation is Key – Dentists must note why selective polishing was necessary.

Tips for Maximizing Reimbursement:

✔ Pre-authorization – Check with the insurer before performing D7670.
✔ Detailed Notes – Explain why selective polishing was needed (e.g., “heavy staining on teeth #8-9”).
✔ Patient Communication – Inform patients if the procedure may not be covered.

7. Best Practices for Dentists Using D7670

• Educate Patients – Explain why selective polishing is being recommended.

• Avoid Overuse – Only use D7670 when truly necessary.

• Stay Updated on CDT Changes – ADA updates codes annually.

8. Patient FAQs

Q: Is D7670 covered by insurance?

A: It depends on your plan. Some insurers see it as cosmetic, while others cover it if medically necessary.

Q: Does selective polishing hurt?

A: No, it’s a painless procedure similar to a regular cleaning.

Q: How often can D7670 be performed?

A: Only when needed—typically during routine cleanings.

9. Conclusion

The D7670 dental code is a valuable tool for targeted stain and plaque removal, offering flexibility in periodontal care. Dentists must use it appropriately, document thoroughly, and communicate clearly with patients. Understanding this code ensures accurate billing and optimal patient outcomes.
