Understanding Dental Code D6098

When to Use D6098 dental code

The D6098 dental code is designated for an "implant supported retainer for a porcelain/ceramic FPD (fixed partial denture)." This CDT code should be used when billing for the retainer component that supports a bridge (FPD) anchored by a dental implant, rather than a natural tooth. It is not used for the implant itself or the prosthetic crown, but specifically for the retainer portion that attaches to the implant and supports the bridgework. Use D6098 only when the clinical scenario involves a porcelain or ceramic fixed partial denture, and the retainer is supported by an implant abutment.

Documentation and Clinical Scenarios

Accurate documentation is essential for successful reimbursement. When using D6098, ensure that the clinical notes clearly describe:

• The presence of a dental implant at the site
• The use of a porcelain/ceramic fixed partial denture
• The specific retainer being placed and its connection to the implant abutment
• Supporting radiographs and intraoral photos, if available

Common clinical scenarios include replacing a missing tooth with a bridge that is anchored by implants rather than natural teeth. For example, if a patient is missing a molar and both adjacent teeth are also missing or unsuitable as abutments, implants are placed, and a porcelain FPD is fabricated with implant-supported retainers at each end. In this case, D6098 is used for each retainer attached to an implant abutment.

Insurance Billing Tips

To maximize claim acceptance and minimize delays, follow these best practices when billing D6098:

• Verify coverage: Before treatment, confirm with the patient’s dental insurance whether implant-supported prosthetics and retainers are covered. Many plans have specific exclusions or limitations for implant-related services.
• Submit detailed documentation: Include clinical notes, radiographs, and a narrative explaining the necessity for an implant-supported retainer. Highlight why a traditional tooth-supported bridge is not feasible.
• Use correct CDT codes: Pair D6098 with related codes as appropriate, such as the code for the implant placement (implant placement code) or the abutment (custom abutment code), to provide a complete picture.
• Review EOBs carefully: If the claim is denied, check the Explanation of Benefits for the reason and be prepared to submit a claim appeal with additional documentation or clarification.

Example Case for D6098

Consider a patient missing teeth #19 and #20. Two implants are placed, and a porcelain FPD is fabricated to replace both teeth. Each end of the bridge is supported by an implant abutment. In this scenario, D6098 is billed for each implant-supported retainer. The claim submission should include:

• Pre- and post-op radiographs
• Detailed clinical notes describing the edentulous span and treatment plan
• A narrative explaining why implant-supported retainers were necessary
• Corresponding codes for implant placement and abutments

By following these steps, dental practices can ensure accurate billing, reduce claim denials, and support optimal patient care through proper documentation and code usage.
