Documentation requirements

D6190 is "by report." That means the chart note and the claim narrative are the procedure's documentation — there is no canonical descriptor element list to fall back on. Per 's implants chapter (pp. 117-122), AAID and ICOI guided-surgery position statements, and modern digital-workflow practice, a defensible D6190 note must contain:

• Tooth number(s) for planned implant site(s) — universal numbering for each planned implant. Single-tooth, multi-tooth, and full-arch cases all need explicit site mapping.
• Type of index / guide — radiographic guide, surgical guide, or combined (dual-purpose) guide. Be specific. "Implant guide" alone is too vague for a by-report code.
• Support type — tooth-supported (the most stable and most predictable), mucosa-supported (fully edentulous arches; requires anchor pins or fixation screws), bone-supported (flapped surgery, rare in modern workflow), or pin-stabilized hybrid. Document support because it drives accuracy expectations and surgical sequence.
• Workflow — analog or digital — analog (alginate or PVS impression, stone cast, diagnostic wax-up, vacuum-formed or acrylic guide with metal sleeves) vs digital (intraoral scan + CBCT, planning software, printed or milled guide). When digital, name the planning software (3Shape Implant Studio, Nobel DTX Studio / NobelClinician, coDiagnostiX, Blue Sky Plan, R2GATE, X-Guide, SMOP, Romexis, BioHorizons IPS, etc.). Software identification supports the narrative and documents the digital-design cost basis.
• Imaging used in planning — CBCT date, field of view (limited / medium / large), and billing code if separately reported (D0364 small FOV, D0365 mandible only, D0366 maxilla / sinus, D0367 large FOV / both jaws, D0368 TMJ). PA(s) and panoramic (D0330) when used in addition. Note diagnostic interpretation of bone volume, ridge contour, sinus floor / mandibular canal proximity, and adjacent root angulation.
• Diagnostic wax-up or virtual setup — when performed, document the prosthetic-driven plan (single crown vs splinted vs fixed bridge vs full-arch fixed / removable), planned occlusal scheme, and how the guide enforces it. The prosthetically-driven language is the single strongest piece of by-report justification.
• Radiopaque markers / scan flags / fiducials — when a radiographic guide is used, document the marker type (gutta-percha / barium sulfate / metal balls / scan-flag composite) and placement. When a digital workflow uses a scan body or fiducial reference, document the reference and the merge / superimposition method (DICOM-to-STL alignment).
• Guide try-in and fit verification — fit confirmed in the mouth (tooth-supported), or seated and stabilized with anchor pins (mucosa-supported); resistance to rotation and rocking checked; bite registration captured if required by the guide system. Some workflows include a try-in radiograph (PA or BW) with the guide seated to confirm marker / sleeve position relative to bone.
• Drill key / sleeve system identification — when surgical use is planned, name the manufacturer's keyed-sleeve system (e.g., Nobel Guided Surgery, BioHorizons IPS, 3Shape / SureGuide, Straumann Guided Surgery, custom-printed sleeves with vendor system specs). The guide is meaningless without compatible drill keys at surgery.
• Implant system selected — when known at the time of guide fabrication, document the planned implant manufacturer, line, diameter, and length per site. The guide and the implant system must be matched.
• Lab / digital design cost basis — in-house vs outsourced; lab name and invoice or in-house design fee. Several carrier clinical-policy bulletins have requested cost documentation on D6190 review; offices that print guides in-house should document chair time and materials in the chart.
• Prosthetic plan the guide is driving toward — single implant crown (D6065/D6066/D6067), implant-supported bridge (D6075-D6077 retainer crowns + D6080 implant maintenance), All-on-X / full-arch fixed (D6114/D6115/D6116/D6117 implant fixed dentures), full-arch removable overdenture (D6118-D6119 / D5863-D5866). The prosthetic endpoint is the why for the guide.
• Indication / clinical necessity language — proximity to mandibular canal or maxillary sinus, narrow ridge requiring precise angulation, prosthetic-driven emergence in an esthetic zone, multi-implant parallelism, immediate placement into a fresh socket, full-arch immediate loading. Reviewers want to see why a guide was clinically necessary, not just that one was made.
• Medical and dental history — reviewed today; flag bisphosphonates / anti-resorptives (MRONJ risk for any implant placement), anticoagulants, immunosuppression, uncontrolled diabetes (HbA1c), smoking, history of head/neck radiation. The history is shared with the upcoming D6010 placement note but should be present here too.
• Vitals — pre-op BP and pulse on the appointment when the guide try-in occurs; required by many state boards on operative visits.
• Informed consent / PARQ — this is typically captured at the implant placement visit, but the guide-fabrication appointment should note that the patient has been informed the guide is part of a planned implant workflow and is not a final restoration.
• Complications / patient tolerance — explicit "None" when accurate, or describe (guide didn't seat fully, required relief; intraoral scan had to be repeated; CBCT fiducial alignment failed and was redone, etc.).
• Next visit — implant placement appointment scheduled with the guide; or, if guide was fabricated for an outside surgeon, transfer of the guide and supporting records (CBCT DICOM, planning report PDF, drill protocol).
• Provider signature and assistant initials.

Two phrases that defuse the most common audit questions: an explicit prosthetically-driven statement ("guide fabricated from CBCT-merged intraoral scan in coDiagnostiX to drive #19 implant trajectory toward planned screw-retained crown emergence") and a clinical necessity sentence ("guide indicated due to 1.8 mm distance from planned osteotomy to mandibular canal on CBCT and need for precise mesiodistal angulation between #18 and #20"). Both track ADA descriptor language and modern guided-surgery standards directly.

Common denial reasons

D6190 is one of the most commonly bundled and denied implant codes. The most frequent reasons it is denied, downgraded, or recouped:

• Bundled into D6010 as "inclusive of implant placement" — by far the most common D6190 denial reason. The carrier's clinical-policy bulletin treats the surgical guide as part of the placement fee. The narrative is the only defense; pre-D is the only reliable way to learn the carrier's stance in advance.
• No narrative on a "by report" code — D6190 without a narrative is auto-rejected on most carrier edits. The narrative must name the guide type, support, workflow, software (when digital), CBCT date, prosthetic plan, and clinical necessity.
• Narrative too generic — "implant guide fabricated" is not a narrative. Reviewers want tooth numbers, guide type, support, workflow, software, CBCT date, prosthetic plan, and clinical necessity language tied to anatomy (canal proximity, sinus, esthetic-zone emergence, parallelism).
• Same-DOS D6190 + D6010 bundled — when both are billed on the same date by the same office, several carriers automatically bundle D6190 into D6010. Staged fabrication at a prior DOS (2-4 weeks ahead) is the documented workaround.
• D6190 billed as a stent/splint code substitute — auditors look for chart language conflating "stent" / "splint" with "guide." the ADA descriptor are explicit that D6190 is not a stent or splint; chart language matters on review.
• D6190 billed for a free-hand placement with no fabricated appliance — flagged on review when the chart describes a free-hand osteotomy with no guide try-in, no marker / sleeve documentation, and no lab or design cost basis. There is no guide to bill.
• D6190 billed for an abutment / restorative jig — abutment try-in jigs, verification jigs, and impression coping indices used during the restorative phase are typically considered part of the abutment / restoration fee, not D6190. Auto-rejected when the DOS is the abutment or crown delivery visit, not the surgical placement workflow.
• D6190 billed for a denture conversion / immediate healing prosthesis — different code family (D5xxx provisional / immediate denture). Auto-rejected on cross-check.
• Missing CBCT in the documentation — most modern carriers expect CBCT to underpin a guided-surgery case. A D6190 narrative without a CBCT date and FOV is weak; many carriers will request the CBCT report on review.
• Missing prosthetic plan — the guide is meant to drive an emergence toward a planned restoration. Silence on the planned restoration (single crown, bridge, full-arch fixed / removable) reads as unprosthetically-driven and weakens the narrative.
• No clinical necessity language — "guide used because we always use a guide" is not clinical necessity. Reviewers look for canal / sinus proximity, narrow ridge angulation, esthetic-zone emergence, parallelism, immediate placement, or full-arch immediate loading rationale.
• Risk-factor patient without narrative — smokers, uncontrolled diabetics, and bisphosphonate / anti-resorptive patients flagged on review without a risk-factor narrative addressing implant prognosis can trigger broader denial of the case beyond just D6190.
• Default-template chart notes — identical guide types, software names, and CBCT findings across multiple patients flagged as templating. Medicaid MCO and several commercial carriers run template-fingerprint review.
• Plan exclusion — some plans simply do not cover D6190 as a non-covered service. The denial is not appealable; the patient is responsible for the fee, and the office should have informed the patient before fabrication.
