D6093 is the CDT code for re-cementing or re-bonding an implant- or abutment-supported fixed partial denture (bridge) that has come loose but is otherwise intact and does not need to be repaired or replaced.
Informational only — confirm the official CDT descriptor and your payers' rules independently. This is general guidance, not billing, coding, or clinical advice.
When to Use the D6093 Code
Report D6093 when a previously placed implant- or abutment-supported fixed bridge loosens or dislodges and is cleaned and re-cemented or re-bonded onto its implants or abutments, with the prosthesis undamaged. It is the bridge counterpart to the single-crown re-cement code.
Keep it distinct. If a single crown (not a bridge) is re-cemented, use D6092. If the bridge or framework is damaged and repaired, use D6090. If a worn attachment part is replaced, use D6091. And note this is the implant bridge re-cement code — re-cementing a bridge on natural teeth is D6930, not D6093.
Documentation & Clinical Scenarios
Re-cement claims should confirm the bridge was simply re-attached:
- Implant/abutment sites and tooth numbers spanned by the fixed bridge.
- That the bridge was intact and re-cemented or re-bonded, not repaired or remade.
- The original seat date if known, since some plans bundle early re-cements.
- A brief note explaining why it loosened (e.g., cement washout) and that retention was restored.
If any component also needed repair or a part replacement beyond simple re-cementation, document it; those carry their own codes (D6090, D6091).
Insurance & Billing Tips
- Verify the re-cement benefit for fixed bridges — coverage and frequency vary by plan.
- Check time-since-placement rules; early re-cements may be bundled into the original bridge service.
- Use the implant code, not D6930 — D6930 is for natural-tooth fixed bridges.
- Distinguish from repair/replacement so you don't bill D6093 when D6090 or a new bridge applies.
- Document the intact bridge to support a clean re-cement claim.
Example Case
A 63-year-old patient's implant-supported three-unit bridge comes loose. The dentist confirms the bridge and implants are intact, cleans the surfaces, and re-cements the bridge — no repair or replacement needed. Because the bridge was seated years earlier and is undamaged, the office files the visit as D6093 (not the single-crown D6092 and not the natural-tooth D6930), with a note documenting the re-cement and the original seat date. The plan pays the re-cement at the expected level.
Patients call because "my implant bridge came loose" or "my implant teeth feel wobbly" — not D6093.

Frequently Asked Questions
What's the difference between D6093 and D6092?
The prosthesis. D6093 re-cements an implant/abutment-supported fixed bridge, while D6092 re-cements an implant/abutment-supported single crown. Both re-attach an intact, loosened restoration; the code depends on whether you're re-cementing a multi-unit bridge or a single crown, so confirm the prosthesis type before coding.
What's the difference between D6093 and D6930?
The supporting structure. D6093 re-cements a bridge on implants or abutments, while D6930 re-cements a bridge on natural teeth. The procedure is similar, but the code depends on whether the bridge is implant-supported or tooth-supported, so verify what the retainers attach to before billing.
Will insurance cover an implant bridge re-cement?
Often, but it varies. Some plans benefit re-cements with a frequency limit, and a re-cement shortly after the bridge was first seated may be bundled into the original service. Verify the re-cement benefit and any time-since-placement rule before billing so the claim is reimbursed correctly.
Do I need a pre-authorization for D6093?
Usually not, since a re-cement is a small, often same-day service, but it helps to know the plan's re-cement benefit and any early-re-cement bundling. Document that the bridge was intact and re-cemented, with the original seat date, so the claim is clean and the patient estimate is accurate.
