When is D3347 used?
The D3347 dental code is applied when retreating a previously performed root canal procedure on a molar tooth. This CDT code comes into play when an existing endodontic treatment requires additional intervention due to ongoing infection, emerging complications, or unsuccessful initial therapy. D3347 should only be applied to molar teeth where the original endodontic treatment was fully completed and properly recorded. For retreatment of other tooth types, different codes apply (D3346 for front teeth and D3348 for bicuspids).
D3347 Charting and Clinical Use
Proper record-keeping is vital for effective billing and insurance coverage for D3347. Clinical documentation must contain:
Comprehensive patient background and symptoms showing the original root canal treatment failed
X-ray documentation (before and after images) demonstrating complications or inadequate healing
Notes about the original procedure and rationale for additional treatment
Detailed records of the retreatment process, including any difficulties or unexpected discoveries
Typical situations include ongoing infection around the tooth root, recurring discomfort or inflammation, or finding previously untreated root canals. Always confirm the original endodontic work was done on a molar tooth and that retreatment necessity is well-documented in patient records.
Billing and Insurance Considerations
To improve payment success and reduce claim rejections for D3347, implement these strategies:
Check coverage details: Review endodontic retreatment benefits and timing restrictions prior to treatment scheduling.
Provide complete records: Include treatment notes, diagnostic radiographs, and detailed explanation of why the original treatment failed.
Apply proper coding: Confirm D3347 applies only to molars and tooth identification aligns with clinical records.
Challenge rejected claims: When claims are denied, examine the explanation of benefits, add supporting materials, and file a detailed appeal explaining treatment necessity.
Active insurance communication and careful accounts receivable management help prevent payment processing delays.
How dental practices use D3347
A 45-year-old individual reports discomfort and inflammation in a lower right back tooth that received root canal treatment two years earlier. X-rays show continued infection at the tooth root. The dentist records patient complaints, examines previous treatment records, and takes new diagnostic images. Following treatment discussion, the dentist completes the retreatment while documenting each procedure step and result. The administrative team confirms insurance coverage, files the D3347 claim with supporting materials, and monitors claim progress. The insurance approves payment, which gets applied to the patient account, showing successful D3347 claim processing.
Common Questions
How does D3347 differ from other endodontic retreatment procedure codes?
D3347 is designated specifically for retreatment of root canal therapy on molar teeth. In contrast, D3346 covers retreatment procedures for bicuspid (premolar) teeth, while D3348 is used for anterior teeth. Proper code selection based on the specific tooth type undergoing retreatment is crucial for accurate billing and appropriate reimbursement.
What are typical reasons for insurance denial of D3347 claims?
Insurance providers commonly deny D3347 claims due to inadequate documentation, absence of supporting radiographic evidence, missing narrative reports that justify medical necessity, or policy restrictions regarding retreatment procedure frequency. Maintaining comprehensive documentation and thoroughly reviewing patient benefit details can significantly reduce claim denials.
Is it possible to bill D3347 alongside other dental procedures for the same tooth?
D3347 may be billed concurrently with additional procedures like core buildup or crown placement when these services are medically necessary and completed within the same treatment session. However, certain insurance plans may bundle specific procedures together or impose coverage limitations, making it essential to verify patient benefits and provide detailed documentation supporting each billed service.
