Simplify your dental coding with CDT companion
When is D6930 used?
The D6930 dental code applies to the re-cementation or re-bonding of fixed partial dentures (bridges). This CDT code is appropriate when an existing bridge becomes loose or detached but remains in good condition and doesn't need replacement. D6930 should not be used if the prosthesis is broken, severely damaged, or when creating a new bridge. Using this code correctly helps dental practices receive proper reimbursement for services while following insurance requirements.
D6930 Charting and Clinical Use
Proper documentation is crucial for successful D6930 billing. Clinical records must clearly explain why re-cementation or re-bonding was necessary, including details like debonding from trauma, normal wear, or loss of retention. Document the condition of supporting teeth, prosthesis integrity, and confirm no underlying decay or issues requiring extra treatment. Photos, X-rays, and clinical narratives explaining medical necessity help support claims and prevent denials. Typical cases include patients with loose bridges after consuming sticky foods or experiencing minor injuries, where both the bridge and supporting teeth remain undamaged.
Billing and Insurance Considerations
Before billing D6930, check patient insurance benefits to confirm coverage for re-cementation procedures. Some plans have frequency limits, waiting periods, or exclude coverage for prostheses placed by other providers. Submit comprehensive claims with supporting materials, including clinical notes and diagnostic images. For denied claims, review the Explanation of Benefits and consider appealing with additional documentation. Recommended practices include:
Verifying eligibility and benefits prior to treatment
Including narratives and images with initial claims
Monitoring claims in your AR system for prompt follow-up
Appealing denials with supplementary documentation
When bridges need extensive repair or replacement, evaluate whether other CDT codes like D6980 (fixed partial denture repair) would be more suitable.
How dental practices use D6930
A patient visits your practice six months after bridge placement, complaining the bridge feels loose but hasn't come out. Examination reveals healthy abutment teeth and an undamaged bridge. You carefully remove the bridge, clean both the abutments and prosthesis, then re-cement using proper dental adhesive. Clinical documentation includes patient symptoms, confirmation of no decay or damage, and re-cementation procedures performed. You submit D6930 with a brief narrative and intraoral photograph to the patient's dental insurance. The claim processes and pays promptly due to complete documentation and accurate code usage.
Common Questions
Is there a specific dental code for re-cementing an individual crown rather than a bridge?
Yes, a different code applies when re-cementing a single crown. The correct code for re-cementing an individual crown is D2920. Code D6930 is designated specifically for the re-cementation or re-bonding of fixed partial dentures (bridges), not for single crowns.
Can code D6930 be used when a bridge needs minor repairs along with re-cementation?
No, D6930 is not appropriate when the bridge requires repairs beyond basic re-cementation or re-bonding procedures. When minor repairs are necessary, such as addressing a fractured pontic or abutment, the appropriate code would be D6980 (fixed partial denture repair). Code D6930 applies only when the bridge remains intact and serviceable, requiring only re-attachment.
What are the typical patient costs for D6930, and how can these expenses be estimated?
Patient costs for D6930 vary based on individual dental insurance plans, including coverage percentages, deductible amounts, and frequency limitations. To provide accurate cost estimates, verify patient benefits prior to treatment, review applicable deductibles or co-payment requirements, and explain any frequency restrictions that might impact coverage. Offering a pre-treatment estimate helps prevent unexpected expenses for patients.
