Dental code D4341 is used for scaling and root planing (SRP), a non-surgical periodontal treatment designed to remove plaque, calculus, and bacteria from below the gumline. Proper use of this code ensures accurate reimbursement and helps patients receive the periodontal care they need.

What is D4341?

D4341 refers to scaling and root planing (SRP) for four or more teeth per quadrant. This procedure is performed when there is evidence of periodontal disease, including bone loss, deep pocketing, and inflammation.

When Should D4341 Be Used?

Use D4341 when:

• Four or more teeth in a given quadrant require SRP due to periodontal disease.

• The patient presents with clinical signs of periodontal disease, such as:

  • Pocket depths of 4mm or greater

  • Radiographic evidence of bone loss

  • Bleeding on probing (BOP)

• The procedure is necessary to remove calculus, plaque, and toxins from root surfaces to improve periodontal health.

When NOT to Use D4341

• For healthy patients – This code should not be used for routine prophylaxis (D1110 for adults, D1120 for children).

• If fewer than four teeth in the quadrant need SRP – Use D4342 instead, which covers SRP for one to three teeth per quadrant.

• For debridement only – If only supragingival calculus removal is performed, use D4355 for full-mouth debridement instead.

Billing and Insurance Considerations

• Insurance carriers often require documentation – Include periodontal charting, radiographs, and clinical notes.

• Frequency limitations apply – Many plans only cover SRP once every 24-36 months per quadrant.

• D4341 and prophylaxis (D1110) cannot be billed on the same day – SRP is a therapeutic procedure, while prophylaxis is preventive.

• Post-operative care may not be included – Some plans do not cover follow-up visits under D4341 and may require separate billing for periodontal maintenance (D4910).

Best Practices for Documentation

To ensure smooth claims processing and avoid denials:

• Record periodontal charting, including probing depths and attachment loss.

• Include intraoral photos and radiographs to support the diagnosis.

• Describe clinical findings in the patient’s notes, such as bleeding, inflammation, and calculus deposits.

• Clearly define treatment necessity to justify the procedure to insurance carriers.

Conclusion

Using D4341 correctly is essential for accurate insurance reimbursement and proper periodontal care. By understanding the criteria, documenting thoroughly, and following insurance guidelines, dental providers can ensure successful claim approval while delivering essential treatment to patients in need of periodontal therapy.
