What documentation is required for D6930?
A defensible D6930 chart note proves three things: (1) the bridge had loosened from at least one abutment in a way that warranted recementation, (2) the abutments and bridge were assessed and judged still suitable for recement (no caries, no fracture, no perio compromise driving the failure), and (3) the recement was performed and the bridge was redelivered in serviceable condition. Include:
- Medical history review and update — meds, conditions, allergies, anti-resorptive therapy, diabetes, parafunction / bruxism. Bruxism in particular is high-yield because it predicts recurrence.
- Chief complaint — in the patient's own words ("my bridge came out while I was eating," "the front bridge feels wiggly when I floss"). Patient narrative often pinpoints the loosening event and is the carrier's first signal that this is a real recement, not a billable extension of a recent cementation.
- Reason for service — short clinical statement: bridge loose on abutment(s), debonded, or removed and reseated for [reason].
- Bridge identification — abutment tooth numbers, pontic tooth number(s), span, retainer material (PFM, full-cast, monolithic zirconia, lithium disilicate, etc.), and original delivery date if known. Original delivery date is the highest-yield audit field on a recement note — it answers the carrier's first question (is this inside the global / warranty period?) before they have to ask.
- Original provider — same practice or different practice. A recement by the original practice within the carrier's global window (typically 6 months, sometimes 12) is generally not billable; a recement by a different practice or after the global window is. Document this explicitly.
- Loosening event / cause — drop, sticky-food dislodgement, gradual loosening over weeks, found loose on hygiene exam, intentional removal for access. Cause matters because it drives the recurrence-pattern decision.
- Pre-recement assessment — before reseating, confirm and document: abutment teeth are caries-free (visually and radiographically), prep margins intact, no abutment fracture or mobility, bridge intaglio clean and intact, no porcelain fracture or framework distortion, soft tissue around abutments healthy, occlusion will re-establish on reseating. The "no caries under the retainer" line is the single most important defensive item in this note. Recementing a bridge over recurrent decay is the headline malpractice-and-recoupment scenario for D6930.
- Radiographs / photos — a current periapical of each abutment to rule out recurrent caries, abutment fracture, periapical pathology, or bone loss is the standard of care on a bridge recement and is independently billable (D0220 / D0230). Many carrier reviewers will pay D6930 on PA evidence alone; absent imaging, the same claim pends for records.
- Bridge integrity assessment — look for: pontic / connector fracture (would push to D6980 repair or new bridge), perforation through the metal substructure or zirconia, porcelain chip on a functional cusp, distortion of the framework. A bridge that fails any of these is not a recement candidate.
- Cement choice and rationale — resin cement (RelyX Unicem, Panavia, Multilink), resin-modified glass ionomer (RelyX Luting Plus, FujiCEM), zinc phosphate, or temporary cement (TempBond, TempoCem) for a planned-failure or evaluation visit. Document the brand and the rationale, particularly if you're using a temporary cement on a permanent bridge as a diagnostic step before recommitting to definitive recement.
- Procedure — bridge removed (if not already off) with appropriate technique (KaVo CoroNaFlex, Richwil, manual coronaflex, ultrasonic loosening), old cement cleaned from intaglio and from abutment preps, abutments cleaned and dried, bridge tried in dry to confirm complete seat, isolation, cement applied per manufacturer instructions, bridge seated under finger pressure or bite-stick, excess cement removed (interproximal floss-through is critical to avoid retained cement causing perio inflammation), occlusion checked with articulating paper and adjusted as needed, contacts verified.
- Post-recement findings — does the bridge seat fully, retain on all abutments, occlude evenly, no patient-reported high-spot. Patient-specific findings, not autotext.
- Patient instructions — soft diet for 24 hours (cement set time varies by product), avoid sticky foods (caramel, taffy, gum), do not floss aggressively under the pontic for 24 hours, return immediately if the bridge loosens again. Document explicitly that the patient was informed a recemented bridge may not retain as long as the original cementation, and that recurrent loosening is a sign of underlying failure that may require a new bridge. This is industry-standard counseling and protects the practice if the bridge re-loosens within weeks.
- Recurrence-pattern documentation — if this is the second or later recement on the same bridge, explicitly document that fact, the prior recement date(s), the cause assessment, the discussion with the patient about replacement vs. another recement, and the patient's choice. The single most important field for defending a claim that the carrier may want to deny as "consider new prosthesis."
- Complications — explicitly noted, even if "none." Common items: residual cement under pontic, occlusal high spot, transient sensitivity on an abutment, partial seat requiring re-removal and re-cement.
- Patient tolerance / response — comfort, occlusion check, ability to chew at dismissal.
- Next visit — typical recall is 1-2 weeks for a post-recement check on questionable cases (recurrence, pre-existing perio inflammation, occlusal concerns), otherwise return to normal recall. If a new bridge is being planned, document the timing.
The "amnesia test" applies: a third party reading the note must be able to reconstruct (1) which bridge was recemented (abutment numbers, span, material), (2) why a recement was the appropriate response and not a new bridge, (3) what cement was used and why, and (4) what the patient was told about future loosening risk. Default-normal autotext (every recement reads "bridge off, cleaned, recemented, occlusion verified") is a known recoupment pattern.
Why does D6930 get denied?
The most common reasons D6930 is denied, downgraded, or recouped:
- Wrong code submitted (D6930 instead of D6092 / D6093) for an implant prosthesis. The most frequent coding error on this code. D6930 is for tooth-borne fixed partial dentures only. An implant-supported single crown is D6092; an implant-supported bridge is D6093. Submitting D6930 on an implant prosthesis is denied as the wrong code or, worse, paid and then recouped on audit when records are pulled.
- Wrong code submitted (D6930 instead of D2920) for a single crown. D6930 is multi-unit only. Re-cementing a single crown on a natural tooth is D2920. A common templating error when an office uses one "recement" macro for both.
- Same-provider global-period exclusion. The original bridge was cemented by your practice within the carrier's global window (usually 6 months, sometimes 12). Carrier denies as "included in the original procedure." Most preventable denial on this code — verify the original delivery date before billing.
- No narrative on a same-bridge recurrence claim — the carrier sees a prior D6930 in their history within their lookback and the current claim has no explanation. Pends for records or is denied outright.
- Insufficient documentation of cause — chart note doesn't describe how the bridge came loose, doesn't state whether the abutments are sound, or reads identically to every other recement note in the practice. Auditors interpret silence as "this looks like a fee-add-on at delivery" and downgrade or recoup.
- No periapical radiograph documenting abutment health — many carriers require imaging on a recement claim, particularly on a recurrence; absent imaging the claim pends or the reviewer denies on the conservative inference that the abutments may be carious.
- Recurrence pattern (third or later recement on the same bridge) — carrier denies with "consider replacement prosthesis." A documented patient-choice-to-recement narrative may overturn on appeal but rarely on first submission.
- Recement on a bridge that the carrier's history shows was just recemented elsewhere — patient transferred between offices and didn't disclose the prior recement. Front-desk eligibility-check practice can prevent this.
- D6930 billed same DOS as the original D62xx / D67xx bridge code — bundled. The cementation at delivery is included in the bridge fee.
- D6930 billed same DOS as D6980 (FPD repair) — most carriers consider the recement bundled into the repair when both are performed at the same visit on the same prosthesis.
- D6930 billed for a temporary / provisional bridge — provisional recements during a global crown-and-bridge phase are bundled into the prosthesis fee. Submitting D6930 for a provisional is denied.
- Default-normal templating — every recement chart note in the practice reads "bridge off, cleaned, recemented, occlusion verified" with no patient-specific findings. State Medicaid OIG audits cite this pattern.
- No documentation that abutments were caries-free — auditors specifically look for this line on a recement note. Its absence is treated as evidence the recement may have been performed over recurrent decay, which is both a denial trigger and a malpractice exposure.
- Bridge was actually a new bridge, miscoded as a recement — coding fraud allegation. Rare but headline-grade when it occurs; charts must clearly distinguish a recement from a replacement.
What do practices ask about D6930?
Is D6930 for an implant crown or for a bridge?+
D6930 is for a bridge — specifically, re-cement or re-bond of a tooth-supported fixed partial denture. The current ADA descriptor is unambiguous on this. Re-cementing an implant-supported single crown is D6092; re-cementing an implant-supported fixed partial denture is D6093. Some chart-note template libraries and PMS macros mislabel D6930 as "recement implant crown" out of legacy habit — that label is incorrect under current CDT and submitting D6930 on an implant prosthesis is a wrong-code denial.
Can I bill D6930 if I cemented the bridge originally?+
Usually no, if the recement is within the carrier's global period for the original prosthesis. ADA bundling guidance and most carrier policies treat a recement performed by the same practitioner / practice within 6 months of the original FPD cementation (some carriers extend to 12 months) as included in the original delivery fee. A D6930 claim filed inside that window will deny as bundled. After the global window, or if the recement is a clearly distinct event well after delivery, D6930 is billable. Recements by a different practice are generally billable from day one.
How often will insurance pay for D6930 on the same bridge?+
Most PPO carriers pay D6930 once per bridge per 12 months; some are stricter (24 months) and some allow more on a case-by-case basis with narrative. A second recement on the same bridge within 12 months is frequently alternate-benefited or denied with "consider replacement prosthesis." A third recement on the same bridge is denied on most PPO plans regardless of timing — the carrier expects a new FPD or replacement of the failing abutment at that point. Always verify the patient's specific plan; HDS, MetLife Federal, and Aetna FEDVIP each define this slightly differently.
Do I need a radiograph to bill D6930?+
Yes in practice, even though the descriptor doesn't strictly require one. A current periapical of each abutment is the standard of care on a bridge recement — it's how you rule out the recurrent caries, abutment fracture, and periapical pathology that would change the procedure from a recement to a new bridge. Many carriers require imaging on the claim, particularly on a recurrence; absent imaging the claim pends or the reviewer denies on the conservative inference that the abutments may be compromised. Radiographs are independently billable under D0220 / D0230 and are not bundled into D6930.
What if the bridge is loose on only one of two abutments?+
This is a clinical red flag, not a routine recement. A "swinging bridge" — fully retentive on one end, debonded on the other — is almost always failing for a structural reason on the loose side: recurrent caries under that retainer, abutment fracture, failed endodontics, or perio compromise with mobility. Cementing a bridge over recurrent decay is the headline malpractice scenario for D6930. The correct workflow is to remove the bridge entirely, evaluate both abutments under microscope and PA, and decide between recement (if both abutments check out), single-unit replacement on the failing abutment, or a new bridge. Document the cause assessment explicitly.
Can I bill D6930 and D6980 on the same day?+
Sometimes, but most carriers will bundle them. D6980 is the FPD repair code (porcelain fracture, connector repair, etc.); D6930 is recement. When both are performed on the same bridge at the same visit (the bridge had to be removed to repair a fracture and was then recemented), most carriers consider the recement included in the repair allowance. To bill both you need to document independent clinical necessity — typically a separate failure mode requiring its own work, not just "removed for access and reseated." Better practice is usually to bill D6980 alone when the recement is incidental to the repair.
What if the bridge has come loose multiple times — should I keep recementing?+
Probably not. A bridge on its second recement within 12 months, or any third lifetime recement, is failing — the prosthesis is past serviceable life or there's an underlying problem (recurrent caries, abutment fracture, perio compromise, occlusal overload from bruxism) that another recement won't solve. The clinical and economic answer is usually a new FPD, a single-unit replacement on the failing abutment, or — if abutment prognosis is poor — extraction and an implant. Carriers will deny a third D6930 on most plans regardless of timing. Document the recurrence pattern, the cause assessment, and the patient's choice; this is the single most important defense if the patient declines replacement and you elect to recement anyway.
